There’s a certain magic to stepping into a Japanese ryokan, a world where the bustle of modern life falls away and tradition, nature, and heartfelt hospitality embrace you at every turn. In Nagato, Yamaguchi, that magic is elevated to an art form at Bettei- OTOZURE, one of Japan’s most serene and refined retreats.
Part of The Ryokan Collection, Bettei- OTOZURE has just 18 rooms, each with its own open-air bath fed by a natural hot spring, set beside the Otozure River in the old spa town of Nagato Yumoto Onsen. The Michelin Guide selected it as a Michelin Key hotel in 2024 and again in 2025.
Yamaguchi, the Old Chōshū Domain Behind the Meiji Restoration
Tucked into the westernmost tip of Honshu, Yamaguchi Prefecture is a hidden gem of coastal beauty, ancient pottery, and rich history. It played a crucial role in the Meiji Restoration, the movement that transformed Japan into a modern nation.
In the 19th century, Yamaguchi, then called the Chōshū Domain, became a hub of reform. Local samurai, alongside allies from Satsuma (modern Kagoshima), led the fight to end Japan’s feudal era and restore imperial rule. Visionaries like Yoshida Shōin from Hagi inspired future leaders, including Japan’s first prime ministers, shaping the country’s new path.

Dassai Sake and the Spirit of Yamaguchi
The region also boasts some of Japan’s purest and most celebrated sake. Chief among them is Dassai, made by the Asahi Shuzo brewery in Iwakuni and revered for pushing the boundaries of traditional sake-making.
Using meticulous techniques and the highest-grade Yamada Nishiki rice, Dassai crafts sakes of extraordinary elegance, delicate, aromatic, and refined, with a smoothness that captures the very essence of Yamaguchi’s understated beauty.
In every sip, you taste the pristine waters, the careful stewardship of generations, and the spirit of innovation that helped shape modern Japan.
Here, the Sea of Japan laps gently against sandy beaches, pine-clad islands dot the Seto Inland Sea, and mountains cradle quiet villages, all waiting to be explored.

Three Days Around Nagato, Hagi and Akiyoshidai
3 Days, 2 Nights at Bettei- OTOZURE Ryokan
Day 1: Arrival and Scenic Encounters
Upon arriving at Ube Airport or Shin-Yamaguchi Station, your journey into Japan’s hidden heartland begins. Before checking in at Bettei- OTOZURE, treat yourself to kawarasoba, “roof-tile noodles”, where tea-flavoured soba, beef, egg, and nori are served sizzling atop a traditional heated tile.
The afternoon is an invitation to explore the area further:
- Tsunoshima Bridge: A ribbon of road arching over vivid blue waters, leading to a tranquil island.
- Higashi-Ushirobata Tanada: Terraced rice paddies cascade gracefully toward the Japan Sea.
- Motonosumi Shrine: Walk through 123 vibrant red torii gates rising from the ocean’s edge, a site believed to bring good fortune.

- To finish your day on a relaxing note, enjoy the public onsen bath in Nagato Yumoto Onsen called “Ontō,” where you can immerse yourself into the symbol of Nagato Yumoto. The owner of the ryokan Bettei- OTOZURE has been involved in renovating this public onsen and it is one of the town’s proudest features. The Ontō bathhouse features wonderfully calming natural hot spring waters.
As evening falls, you finally arrive at Bettei- OTOZURE Ryokan, nestled beside the Otozure River in the historic hot spring town of Nagato Yumoto Onsen which is symbolised by the historic “Ontō” public bathhouse. The town’s hot spring tradition goes back some 600 years, the longest of any spa in Yamaguchi Prefecture, and the Fukagawa kilns nearby have been firing Hagi ware for around 360.
After changing into a yukata, indulge in an exceptional dining experience, choosing from refined kaiseki or theatrical teppanyaki, served on Hagi-yaki pottery. We particularly recommend the outstanding Japanese kaiseki course dinner for your first night at Bettei- OTOZURE and the teppanyaki course dinner for the second night.

Post-dinner, stroll under the crystal-clear rural skies or visit the astronomical observatory at Otani Sanso to admire the constellations.
Day 2: Cultural Immersion and Hands-On Craft
Following a leisurely breakfast overlooking serene gardens, prepare for a truly intimate cultural encounter.
The morning features a VIP visit to a Hagi-yaki master potter’s studio. With deep connections to Bettei- OTOZURE’s owners, this master potter, from one of the Hagi ware families that have handed the craft down through the generations, offers guests a rare glimpse into a craft that began as the official kiln of the Mōri lords and became prized by tea masters. You may even try your hand at moulding a keepsake.

The afternoon invites you to wander Hagi City:
- Explore narrow streets lined with samurai residences and merchant houses. Hagi’s castle town and Shōka Sonjuku, the school where Yoshida Shōin taught, are part of the UNESCO-listed Sites of Japan’s Meiji Industrial Revolution.
- Visit museums rich with Meiji-era artefacts.
Optional seasonal activities include:
- Barbecuing on the grassy plains at Senjojiki.
- Scuba diving in the clear waters around Ōmijima island.
- Sea kayaking along the dramatic Yuya coast.
In the evening, return to Bettei- OTOZURE for another unforgettable meal (our personal favourite was the delicious teppanyaki course dinner). This unique dinner experience blends traditional hospitality with modern culinary artistry. Guests are seated around a polished iron grill, where a master chef prepares each course with precision and theatrical flair.
The menu often features the finest local ingredients, such as tender Yamaguchi Wagyu beef, fresh seasonal seafood, and vibrant organic vegetables, all cooked to perfection before your eyes. Each sizzling bite is paired thoughtfully with regional sake or fine wine, enhancing the flavours and the immersive atmosphere. The experience captures the essence of Japanese omotenashi, genuine, heartfelt service, and it was the highlight of our own stay.
After this culinary delight, unwind with a soak in your private open-air bath, watching river mists rise under the moonlight.

Day 3: Departure Through Natural Wonders
Having enjoyed one final sumptuous breakfast, it’s time to check out.
En route to the airport or station, explore the dramatic Akiyoshidai Plateau, a surreal landscape of limestone spires and rolling grasslands. Don’t miss the chance to venture into Akiyoshido Cave, one of Japan’s largest limestone caves. It runs for more than 10.7km, about 1km of which is open to visitors, and stays at 17°C all year. Adult admission is 1,600 yen, rising to 1,900 yen over Golden Week and in July and August and falling to 1,350 yen from December to February. It is open every day, 8.30am to 5.30pm from March to November and 8.30am to 4.30pm from December to February, and a visit takes about an hour.

If time allows, a stop at the Akiyoshidai International Art Village offers a last glimpse of Yamaguchi’s creative spirit before your departure.
