A Luxurious Hot Spring Escape in the Heart of Oku-Boso's Natural Beauty
Enjoy a serene getaway at Shinra Yoro Valley, a luxury hot spring resort nestled in the Yoro Valley of Chiba Prefecture, where guests can immerse themselves in seasonal landscapes and rejuvenating black hot springs.

Escape the urban rush for a tranquil retreat in one of Boso Peninsula's most scenic destinations, where pristine nature meets refined hospitality.
Freshly opened in the spring of 2025, the Shinra Yoro Valley resort sits harmoniously along the Yoro River in Oku-Boso, Chiba Prefecture. This luxurious resort invites you to experience the valley's dramatic beauty, carved over millions of years by the river flowing from the Kiyosumi Mountains. The property seamlessly blends into the mystical landscape, offering an intimate connection with nature's elements—flowing water, untouched forests.

The resort's signature feature is its renowned kuroyu, or "black hot spring," celebrated throughout the region. Guests can soak in these therapeutic waters while gazing at the Yoro River and the spectacular Kengai-kyo cliffs. Accommodations include guest rooms with private open-air baths, ensuring a secluded onsen experience accompanied by the gentle sounds of the stream. Additional facilities include an innovative "Heated Pool Ro,"—a unique combination of swimming pool and open-air bath—along with private baths featuring saunas and a lounge overlooking breathtaking cliffs.

Dining at Shinra Yoro Valley celebrates Boso's position between mountain and sea. The Japanese cuisine showcases the peninsula's diverse seasonal bounty, from fresh seafood to renowned agricultural produce and game meats, all presented on carefully selected tableware that enhances the aesthetic experience.

Beyond the resort, the Yoro Valley area offers numerous attractions for exploration. The magnificent Awamata Falls—considered Boso's premier waterfall—and the surrounding area are perfect for nature walks, while the Kobundo Ruins provide scenic vistas. The valley's autumn foliage is especially beautiful, making it an ideal place for leisurely fall visits. For those seeking respite from city life, Shinra Yoro Valley delivers an unforgettable sanctuary where water's gentle rhythm and birdsong create the perfect backdrop for rejuvenating your spirit. The resort embodies the philosophy "Empty your mind. Be like the rippling of water," inviting guests to flow naturally into complete tranquility.
