Historically speaking, few things were as influential in shaping the people’s image of their own country as pilgrimage trails. Guided by religious causes, these journeys were the first time many citizens, both poor and wealthy, got to know the extent of the land they called home. Japan, unsurprisingly, was no exception. Japanese pilgrimages, and their subsequent secularisation, were instrumental in shaping the nation into the one we know today. Japanese hot springs (onsen), for example, owe their success to the Buddhist pilgrims of ancient times. The developments themselves took centuries to be properly established, and we couldn’t in good faith attribute them to a single trail; however, if we had to choose one, our pick would undoubtedly be the Kumano Kodo Trail, the most important Japanese pilgrimage.
Today, as part of a collaboration with Jetpac eSIM, we want to tell you everything about this fascinating and life-changing experience. Let us be direct: we want you to take the Kumano Kodo Trail. We believe the Kumano Kodo Pilgrimage is the thing your adventurous mind never knew it needed to do. So take the following Kumano Kodo guide as a letter from Japanese culture lovers: an invitation to see things as we do, through a fascinating journey full of spiritual significance and natural beauty. If you want to embark on this quest, keep reading.
What is the Kumano Kodo?

If you’re reading this, it means you’re willing to take the first steps into this enthralling adventure, so, what are you signing up for? What is the Kumano Kodo Trail? To put it simply, the Kumano Kodo is a 1000-year-old Shintoist pilgrimage across the mountainous Kii peninsula. It is a network of routes with no single end point, and every one of them leads to three Grand Shrines. These are the Hongu, Shingu and Nachi Shrines, collectively known as the Kumano Sanzan. The Kumano Kodo pilgrimage can start as soon as one arrives at either Kyoto or Osaka, but the historically most famous route begins at Tanabe City.
This is all useful information you’ll need to know, however, it’s not why you’re here. Why does the Kumano Kodo stand out? How has it remained relevant for over a thousand years? The answer to both of these questions is its spiritual significance. As early as the Heian Era, emperors of the then capital, Kyoto, found themselves drawn by the spiritual ambience of the Kumano Kodo, travelling to write poetry, perform ritual dances and bathe in the purifying rivers. One such pilgrim, the retired emperor Go-Shirakawa, made the journey more than 30 times during the turbulent late twelfth century, and did so to ask the kami for peace. As history became myth and myth became legend, Japanese pilgrims sought to follow in Go-Shirakawa’s footsteps.
Eventually, the Kumano Kodo became famous across Japan, and seekers of truth, either religious or not, took the trail. Time, in fact, only made it more relevant. UNESCO, for example, recognised it as a World Heritage Site in 2004, a feat it shares with only one other pilgrimage trail (The St James Way).
So, now that you know what the Kumano Kodo is, how do you start?
The Kumano Kodo Pilgrimage Routes

As previously stated, the Kumano Kodo Pilgrimage doesn’t have a clear destination. As such, it doesn’t have a clear beginning either. There exist six different routes that are considered part of Kumano Kodo, all of which vary in scenery, length and difficulty. Choosing a route is, therefore, the most important decision when embarking on this journey.
As you might have guessed, finding the perfect route is a personal decision. Are you more of an avid hiker or a curious historian? Are you guided by the promise of natural beauty or religious significance? In either case, our goal here is to encourage that adventurous part of you. Whatever route best suits your preference, you will find it in the following segments. For the sake of convenience, we’ll include the estimated lengths in kilometres and time durations.
Nakahechi Route
The Nakahechi route, also known as the Imperial Route, is the most famous and important route of the Kumano Kodo. Beginning at Tanabe City, the Nakahechi route was built over 1000 years ago to provide direct passage to Kumano Sanzan. Therefore, the Nakahechi is the most accessible and versatile route of the Kumano Kodo. As a matter of fact, many of the other routes end up connecting to it.
As the name “Imperial Route” suggests, this was the route the emperors took when embarking on their pilgrimages. For this reason, Nakahechi has a unique historical and cultural atmosphere, one that will, on occasions, transport you to the Heian Era. This being said, the route is somewhat touristic, with English signs, maps and luggage shuttle services across the way. These features aim to make the Nakahechi route more comfortable, and I would argue they do so without sacrificing immersion, but that’s up to you to decide.
The route itself would be best defined as moderately difficult. It’s by no means the easiest route, with a mountainous environment that will test your abilities and endurance; but it has enough villages, one could easily find places to rest. In any case, it’s best to go prepared.
🏃 70 Kilometres
🕗 4 to 5 days (some itineraries go up to 7 days)
Iseji Route

Substantially longer than the Nakahechi Route, the Iseji Route is a gateway to ancient Japanese religious practices. The distinctive feature of this route is it begins at the Ise Grand Shrine, located at Ise in the Mie Prefecture. This shrine, dedicated to the solar goddess Amaterasu, is considered the most important shrine in Shintoism. Consequently, the Iseji route holds the biggest spiritual significance out of all the Kumano Kodo trails in Shintō, as it connects two religiously important places of this faith.
Besides this, the main draw of the Iseji Route is its natural beauty. The route traverses the east coast of the Kii peninsula, which means breathtaking scenery of rivers, beaches and mountains. For this reason, Iseji is often called the most beautiful way to get to Kumano Sanzan.
In terms of difficulty, the Iseji Route could be considered comparable with the Nakahechi Route, as the terrain is quite similar. However, at around 170 kilometres the Iseji route is more than twice as long, meaning it will test your endurance in a more arduous way. The northern stretch is mostly flat and on paved roads, while the central section crosses a series of cobblestone passes between small coastal fishing villages. Expect a journey across varied terrain, with both high and low moments of intensity, that will ultimately reward your perseverance.
🏃 170 Kilometres
🕗 10 to 14 days
Ohechi Route
Perhaps the most romantic route of the Kumano Kodo pilgrimage, the Ohechi Route thrives in its immersive capabilities. Developed in the 15th century and used for both worship and sightseeing, Ohechi begins at Tokei-jinja Shrine in Tanabe City and follows the southwest coast of the Kii peninsula to Fudarakusan-ji Temple in Nachi. The coastal scenery was especially important to its development, as Japanese poets and writers of the Edo Period were attracted by it.
As for the immersion part, the Ohechi Route is favoured among many Japanese citizens, as it’s arguably the least touristic. The journey across the southwest coast is full of small villages that feel like a journey into the past, aided by the fact the signage along the way has some segments where English is nowhere to be found. Don’t worry though, as if you travel with our partner Jetpac eSIM, you’ll have fantastic travel data that ensures you won’t get lost.
Finally, the Ohechi Route could be considered the least difficult route of Kumano Kodo. This is due to modern developments, as some sections have been transformed into paved roads, making them substantially easy to traverse. Keep in mind that, when we say this is the least difficult, we are saying it relative to the other routes, as this is still a days-long trek you’ll need to be prepared for.
🏃 65 Kilometres
🕗 3 to 4 days
Kohechi Route

The Kohechi Route, also known as the mountain trail, aims to bring spirituality to a more grounded level. Similarly to the Iseji Route, it connects another religiously important place to the Kumano Sanzan, beginning at Mount Kōya (Kōyasan). However, if you’re familiar with Kōyasan, you’ve already realised the particularity of this route, as it is a Buddhist worship place. The Kohechi Route, therefore, connects two different faiths’ sacred sites, finding common ground in their pursuit of spiritual truths.
Furthermore, the route’s existence serves as a reminder of Japanese history. Back when it was developed, around the 13th and 14th centuries, Buddhism and Shintoism were closely intertwined. There were purists on both sides, but blended Shinto and Buddhist teachings were practised across the nation. That only changed in 1868, 15 years after the opening of Japan’s borders, when the new Meiji government ordered the two faiths to be separated. So, in many ways, the Kohechi Route is a way back to that earlier period, when religious practice was guided as much by healing the soul as by doctrine.
If the name “mountain trail” is any hint, this is one of the most difficult routes in the Kumano Kodo trail, and the Tanabe City Kumano Tourism Bureau recommends it for experienced hikers only. The journey includes several passes over 1,000 metres in elevation, so your endurance will constantly be tested. Additionally, the weather can be quite a hassle, with rain, wind and fog being all possible outcomes. From mid-December to mid-March, the route is officially closed because snow can block the high passes, although the Hatenashi Pass section at its southern end stays open all year. This being said, the Kohechi Route does have some of the best hot spring villages, like the Totsukawa Onsen, so it has some of the most relaxing moments too.

Omine Okugakemichi

Representing a 1300-year-old tradition, the Omine Okugakemichi stands out in the Kumano Kodo trail as a true test of one’s capabilities. The route begins at Yoshino Kumano National Park, specifically at the town of Yoshino, and crosses the Ōmine Mountains to Kumano Sanzan. These mountains, which include both Mount Yoshino and Mount Ōmine, hold spiritual significance in the indigenous practice of Shugendō, a tradition of pre-feudal Japan. For Shugendō practitioners, these mountains are both places of worship and testing grounds for devotees, which makes the route a mental, physical and spiritual trial as well as a pilgrimage.
Here, we must address one of the most controversial aspects about the Omine Okugakemichi, and that is the gender restrictions in place. For religious reasons, women are not allowed to get to the top of Mount Ōmine, a tradition Shugendō practitioners proudly uphold. This is, however, not a legally enforced restriction, and many Japanese women over the years have climbed Mount Ōmine in protest without consequence. This being said, women can still be criticised for not being “respectful” of the traditions, which is why some deviations exist. As a side note, nearby Mount Inamura (Inamuragatake) has been open to women as a Shugendō training mountain since 1959, and is known as the Women’s Ōmine.
In terms of difficulty, the Omine Okugakemichi is widely considered one of, if not the most, difficult pilgrimages in Japan. Across this journey you’ll encounter rocky terrain, steep climbs and constant elevation changes, making it quite fitting for its status as a mental and physical test. Arduous preparation and several days of food and water are required.
🏃 Approximately 170 Kilometres
🕗 About 5 days
Kiiji Route

The precursor to the Nakahechi Route, the Kiiji Route follows the emperors of old as they travelled from Osaka to Tanabe City. Due to its unique location, this is the easiest way to start the Kumano Kodo trail, as Osaka is well-connected with all of Japan. For this very reason, most people hike sections of the Kiiji Route rather than the whole trail. This could be done as both preparation for the Kumano Kodo trail, or a quick hiking escape from Osaka.
Considering there exists direct transportation from Osaka to Tanabe, it’s normal to ask, are there any benefits from taking the Kiiji Route? As a matter of fact, there are some noteworthy locations you could only access by taking this approach. Fujishiro Shrine in Kainan, for example, was one of the five most prestigious Gotai-oji shrines on the route and a key stop for imperial pilgrims. Not far away are the remains of Haraedo-oji, where pilgrims purified themselves before entering Kumano, and where, records say, a torii gate stood as the first sacred entrance to Kumano.
In terms of difficulty, the Kiiji Route follows both old pilgrimage roads and modern paved ones. The older segments provide a challenge and the modern ones an easier terrain to traverse. This is to say, the Kiiji Route is comparable to the Ohechi Route in terms of difficulty, although it’s longer. This being said, it also features more places to rest, as it traverses some populated areas. In short, expect a moderate hike.

Kumano Kodo Accommodation: Hotels, Ryokan and Guesthouses
Image credit: Kumano Travel
Considering that, depending on the route, the Kumano Kodo trail can take up to two weeks to finish, it’s common to feel anxious about the question: where would I sleep? This question has haunted even the emperor of ancient Japan, as, at the end of the day, we all have human necessities. However, as hinted at the beginning of this article, the rise of religious pilgrimage also led to the rise of accommodations in Japan. The Kumano Kodo, being the most important pilgrimage trail, was among the first to generate these new businesses around it, especially in hot springs villas.
This is to say, you’ll have a varied amount of options for accommodation during the Kumano Kodo trail. These include western style Hotels, Ryokan Inns, Guesthouses and even rental homes. We won’t go over any specific examples, as there are more than 13 different areas where accommodations can be found, and covering them deserves its own article. For now, we recommend you visit the Kumano Travel Site, as it has a compiled segment on accommodation based on route.
Finally, we must mention once again our partner Jetpac eSIM, as the possibility of having travel data while looking for accommodation is invaluable. With their reliable services, you’ll be free to explore the Kumano Kodo trail without what if scenarios holding you back.
Kumano Sanzan: Hongu, Hayatama and Nachi Grand Shrines
By this point, it should be obvious that the Kumano Kodo Trail is above all about the journey. Even so, there are some absolutely breathtaking sites awaiting the adventurous souls that took the pilgrimage. We are, of course, referring to the three grand shrines that compose Kumano Sanzan.
Before we dive into the shrines, we must address a question that’s been underlying this entire article: why Kumano? Why not, let’s say, Kyoto, widely considered the spiritual capital of the nation? Although it’s tempting to say Kumano stands out because three Grand Shrines were built there; the reality is the other way around. Ever since prehistoric times, the Kumano region has been considered spiritually special. Its mountainous terrain has always awakened a sense of awe and wonder in people. As a matter of fact, in Shintoism it’s associated with the Yomi-no-Kuni, land of the dead; in Japanese Buddhism, it’s the celestial realm. Kumano was, in short, a place above this earth, where one could heal their soul, and, because of the hot springs, their body too.
So, without further ado, let’s dive into the three grand shrines that embody the essence of this sacred region.
Kumano Hongu Taisha Shrine

Mainly dedicated to the Kumano Gongen, a deity believed to be a manifestation of Buddha incarnated as a Kami, the Kumano Hongu Taisha Shrine captures the confluent spirituality of the Kumano region. Originally, it was built in Ōyunohara, a sandbank where the Kumano and Otonashi Rivers meet. However, after a flood in 1889 destroyed much of the structure, the salvaged remains were rebuilt at the present site. This ended up being beneficial, as the Kumano Hongu Taisha Shrine is now located in a much safer place; not to mention, now all the Kumano Kodo Pilgrimage routes lead to it.
That blend of Buddhist and Shinto belief was normal across Japan for most of its history, and Kumano was one of its great centres. It ended by law in 1868, when the new Meiji government ordered the separation of Shinto and Buddhism, known as shinbutsu bunri. The order banned the use of gongen as a title for kami, and Buddhist priests, images and buildings were removed from shrine grounds across the country, including at Kumano.
As for its original site, Ōyunohara, a Torii shrine gate was erected in the year 2000 to serve as a gateway to the sacred Kumano area. In fact, this gate, officially titled Otorii, is the largest Torii shrine gate in the world, coming to an astonishing 33.9 metres tall and 42 metres wide.
As for the architecture of the Kumano Hongu Taisha Shrine, the original site at Ōyunohara had five main pavilions enshrining 12 deities, as well as a stage to perform theatre, dance and other rituals. Over the years, many of these were destroyed and faithfully rebuilt, until the flood of 1889; only three of the five main pavilions were rebuilt at the present site. The buildings themselves were made using natural unfinished material of the area, which lets the shrine blend with the environment. The particular stand out, architecturally speaking, can be found in the roofs. These are entirely made of Hinoki, Japanese cypress bark, replaced every 40 to 50 years, and are decorated with ornaments in a style called Chigi, common on many Japanese shrines.
Kumano Hongu Taisha Spring Festival and Yata-no-Hi Fire Festival

There exist two festivals that are celebrated around the Kumano Hongu Taisha Shrine: the Kumano Hongu Taisha Spring Festival, and the Yata-no-Hi Matsuri Fire Festival. Additionally, it should be noted that Otorii is lit up during these events, to commemorate their spiritual importance.
The first one, the Spring Festival, is held between the 13th and 15th of April, and is intimately associated with the Kumano Kodo pilgrimage. The first day, fathers and sons wearing traditional costumes go to purify themselves in the waters of Yunomine Onsen, right before walking the Kumano Kodo route to Ōyunohara. It’s quite a sight to behold, as the young boys are not allowed to touch the ground, meaning their fathers carry them over their shoulders the entire time. The last day, Kumano deities are invoked to take temporary residence in a portable shrine (mikoshi), before being transported to Ōyunohara. Once there, various rituals and celebrations take place, such as fire rituals and mochi rice cake scramble.
The Yata-no-Hi Matsuri Fire Festival, on the other hand, is celebrated the last Saturday of August, once again in Ōyunohara. This festival honours Yatagarasu, the crow revered as the messenger of the Kumano deities. Yatagarasu, a three-legged crow, is closely related to the pilgrim history of the region, as it is said to guide travellers in their spiritual journeys. As for the festival, it includes fire mikoshi, a Taiko drum show, dancing, and fireworks, with the Otorii as a backdrop.
The crow’s reputation as a guide comes from one of Japan’s founding legends. The Kojiki and Nihon Shoki, Japan’s eighth century chronicles, tell how the legendary first emperor, Jimmu, landed at Kumano on his campaign east and found his way inland blocked by mountains, until the sun goddess Amaterasu sent Yatagarasu to lead him through to what is now Nara. Frank Brinkley pointed out in A History of the Japanese People (1915) that the three-legged sun crow itself comes from Chinese myth. Far from the Kii mountains, Yatagarasu also appears on the badge of the Japan Football Association.
Kumano Hayatama Taisha Shrine

The Kumano Hayatama Taisha Shrine is a place that, quite literally, blends its unique location with its purpose as a place to worship. Alongside the spiritual pull of the wider Kumano area, this shrine is considered a place to worship nature itself. It is located at the mouth of the Kumano-gawa River, next to the Pacific Ocean, surrounded by trees of the mountainous Kii peninsula. Additionally, it stands next to an 800-year-old Nagi-no-Ki tree, a sign of how old the bond is between the shrine and the nature around it. The Kumano Hayatama Taisha Shrine is, in short, one with nature, and praying there is, by extension, a way of appreciating nature’s beauty.
Shingu also keeps a tradition that reaches back to ancient China. Xu Fu, known in Japan as Jofuku, was a scholar sent by the Chinese emperor Qin Shi Huang in the third century BC to find the elixir of life. Local tradition says he landed on this coast, chose to stay, and taught the people farming, fishing and whaling. His grave stands in Jofuku Park, a minute’s walk from JR Shingu Station. Frank Brinkley described a tomb inscribed as the grave of Xu Fu near Shingu, with mounds said to belong to his companions, in A History of the Japanese People (1915), and treated the story as tradition rather than proven history.
Mifune Matsuri Boat Race and Oto Matsuri Fire Festival in Shingu

Similarly to the previously mentioned shrine, the Kumano Hayatama Taisha Shrine has two festivals around it, both of which hold special spiritual significance.
The first one is the Mifune Matsuri, which is not to be confused with the festival of the same name celebrated in Kyoto. Whereas the Kyoto festival is an elegant boat spectacle commemorating emperors of old, the Kumano festival is a fierce boat race. Celebrated on October 16th, nine boats of men compete to be the first to traverse the Kumano-gawa River to the Mifune-jima Island. Here, once again, a portable shrine is used, which transports a deity to the Mifune-jima Island, thought to be a sacred place of rest. Over the years, the popularity of this festival has grown, and in 2016 the Japanese government designated it, together with the Oto Matsuri, an Important Intangible Folk Cultural Property.
The second festival is the Oto Matsuri, a fire festival held at Kamikura Shrine, part of Kumano Hayatama Taisha. Held on February 6th, this festival sees men of all ages dressed in white to symbolise purity. Furthermore, participants, called noboriko, only eat white foods during this day. Once the daylight starts to fade, the noboriko are instructed to carry a torch lit from a sacred fire. As the torch burns and the sensation of fire becomes palpable, the shrine gates open up and participants race down the mountain. The result? A fiery path resembling a dragon emerges, the sky changes colour and the smoke blends with each participant’s best wishes, taking them beyond this world.
Kumano Nachi Taisha Shrine

The last of the grand shrines, and most likely the second one you’ll visit (independently of the route you choose), the Kumano Nachi Taisha Shrine is perhaps the most beautiful of the three. Located 350 metres above sea level, this shrine rests next to, and was built to worship, the legendary waterfall Nachi-no-Otaki. The striking colours of the structure next to the waterfall already makes for one breathtaking sight; but add to this the trees that surround the mountainous environment, and the Shrine stands out as something straight out of paradise.
Regarding the Nachi-no-Otaki, this is the tallest waterfall in Japan, standing at an impressive 133 metres. It’s so tall, in fact, that it can be seen from far out on the Pacific Ocean. Much like the Kumano area itself, this waterfall was considered a sacred site before Shintoism was properly established as a religion. As an example, Shugendo practitioners, which we’ve discussed in the Omine Okugakemichi route, revered the place for its spiritual importance.
Nachi-no-Hi Matsuri Fire Festival on 14 July
Image credit: Oh! Matsuri
The Kumano Nachi Taisha Shrine has one main festival: the Nachi-no-Hi Matsuri Fire Festival. Held annually on July 14th, this festival may feel quite similar to the Oto Matsuri, in that it’s a fire festival where men carry torches and dress in white. However, this is as far as similarities go. The torches here weigh as much as 50 kilograms each, requiring much more endurance and strength to carry, and they are carried at a walk. Their flames purify the twelve fan-shaped portable shrines (ogi mikoshi), one for each month of the year, which stand 6 metres tall and represent the waterfall, keeping the sacred waters pure.
Seiganto-ji and the legend of Mongaku at Nachi Falls
Right beside the shrine stands Seiganto-ji, a Buddhist temple that is the first stop on the Saigoku Kannon Pilgrimage, a circuit of 33 temples dedicated to Kannon, the bodhisattva of compassion. Its founding legend tells of Ragyo, an ascetic from India, who found a golden statue of Kannon in the pool beneath Nachi Falls. Until the end of the Edo period the shrine and the temple were run together as a single institution known as Nachisan. The 1868 separation order forced the temple’s priests out, and Seiganto-ji was only allowed to re-establish itself in 1874. Writing in Romances of Old Japan (1919), Yei Theodora Ozaki still called the waterfall itself the first of the thirty-three places sacred to Kannon, a sign of how closely the falls and the temple were tied together in people’s minds.
The falls are also the setting for one of the best known penance stories in Japanese literature. The Tale of the Heike tells how the monk Mongaku, a former palace guard, stood beneath the icy falls in the depths of winter to atone for his sins, and nearly died before, the story says, two attendants of the deity Fudo Myoo came down to save him. The legend later reached the stage as The Priest Mongaku at the Waterfall of Nachi, which Ozaki retold in the same book, and it became a favourite subject for woodblock print artists.
The Dual Pilgrim: Kumano Kodo and the Camino de Santiago
Finally, to conclude this article, we want to share a fact most people aren’t aware of regarding the Kumano Kodo: its relationship with The Way of St. James. A common name for the Kumano Kodo is the Japanese Camino, in reference to “El Camino de Santiago”, which is how the Way of St. James is known in Spain, and the two are the only pilgrimage routes registered as a UNESCO World Heritage Site. They are also officially sister trails. Wakayama Prefecture and the Spanish region of Galicia have had official relations since 1998, and on 1 February 2015 Tanabe City and Santiago de Compostela launched the Dual Pilgrim programme to recognise the adventurous souls who complete both trails.
Of course, there is no reward that could remotely encapsulate such a monumental achievement as completing both pilgrimages. Nevertheless, Dual Pilgrims receive a limited edition pin badge and a certificate of completion made from local washi paper, and can choose to be listed on the spiritual pilgrim website.
Having made it this far into the article, we’re sure your dauntless spirit is ready to embark on this fantastic journey. So, as one last piece of advice, whether you’re ready to take on the Kumano Kodo trail, or are looking for that Dual Pilgrim recognition, make sure to do so with Jetpac eSIM. With their fantastic travel data, you’ll have fast internet access in Japan, Spain and anywhere in the world. We’re sure you won’t miss out on this great adventure, and, as our esteemed reader, we want you to have the best experience possible.
