Hiranoya Ryokan & Sauna

Aichi Prefecture/Mitani Onsen

A long-established Ryokan where you can unwind with the ever-changing seasonal views of Mikawa Bay and soothing hot springs known for beautiful skin.

Hiranoya is the oldest ryokan in Miya Onsen, nestled in the scenic Mikawa Bay. Located on a hill, it offers stunning views of Mikawa Bay that change with each season. This ryokan takes pride in its Kaiseki cuisine featuring delicacies from the mountains and sea of Mikawa, as well as exquisite deep-sea fish dishes from Gamagori. The buffet with 40 Japanese and Western dishes, including Mikawa beef steak, is also popular. Guests can enjoy the natural onsen "Bihaku-sen," known for its beautifying properties, through four unique baths within the facility. Conveniently located just a 3-minute drive from the multi-resort facility "Laguna Ten Bosch," Hiranoya offers free shuttle service and is highly rated as a base for visiting Laguna Ten Bosch. Additionally, Hiranoya is one of the few accommodations in Miya Onsen where guests can stay with their pets (small dogs only). Various pet-friendly plans are also available.

  • We had a wonderful stay.The open-air bath was a very calming space, and we were able to relax while listening to the sound of water and insects. The shampoo was also comfortable and didn’t leave our hair feeling squeaky. The Ryokan itself was spacious and felt like a maze, making it fun to walk around as if exploring. The barley tea and apple rooibos tea after the bath were also a thoughtful touch.I hadn’t been reading much for quite some time, but using the “Kotoba no Atelier” inspired me to make time for reading again in my daily life after this stay. I also wrote a Tokitegami letter and had a lovely time.Breakfast was buffet-style and everything was delicious—especially the fruit punch. Before breakfast, I ground coffee beans for drip coffee, which was also excellent and made for a very fulfilling experience.

  • My spouse and I stayed for one night with our dog.The property was clean and very welcoming, and the rooftop dog run was great.There was no dinner, only a breakfast buffet, but the selection was extensive and everything was delicious.The staff were attentive, so we could enjoy our meal comfortably.If I had one complaint, it would be that the parking lot is small; since we arrived later, we had to park in the second or third lot down below and walk up the hill, which felt quite far.

Introduction of the Accommodation

Kaiseki Image

A traditional Ryokan boasting Mikawa's mountain and sea delicacies, as well as exquisite deep-sea fish cuisine from Gamagori.

Hiranoya was established in 1932 as a small culinary Ryokan. Mikawa is blessed with a mild climate throughout the year and is surrounded by nature, including the sea and mountains. Our head chef carefully prepares each dish using locally sourced ingredients to bring out the natural flavors of this region. In Gamagori, where Hiranoya is located, rare deep-sea fish such as Mehikari, Nigis, and Akasaebi are caught in abundance—different from those found in Ise or Mikawa Bay. Gamagori is the only place in the prefecture where offshore bottom trawl fishing takes place, making these fish a local specialty. At our Ryokan, we offer luxurious kaiseki cuisine featuring these premium deep-sea delicacies for your enjoyment.

Buffet

The "Japanese-Western 40-Item Dinner Buffet," featuring freshly grilled Mikawa beef steak, is also highly recommended.

In addition to kaiseki cuisine, our Japanese-Western dinner buffet featuring 40 dishes is also highly popular, offering a rich taste of Mikawa. Enjoy freshly grilled steak from Aichi Prefecture's renowned wagyu brand, "Mikawa Beef." The buffet also includes freshly fried tempura, a salad bar focusing on vegetables, and a dessert corner, making it especially popular with families.

Experience ultimate relaxation in our meticulously designed sauna.

At Hirano-ya, we offer a premium sauna experience that has won the "Japan Space Design Award 2023" and the "DFA Design for Asia Awards 2023." Our private saunas, "shiro" and "tya," allow you to customize lighting, temperature, and music. Adjust the brightness freely, set the temperature from 60°C to 99.5°C in 0.5°C increments, or play your favorite music via Bluetooth speakers—relax in an environment tailored just for you. After sweating it out, enjoy an outdoor cool-down while admiring nature or art installations. The "Cave Sauna" features IKI by renowned manufacturer METOS. Using sauna stones recognized even in Finland—the home of saunas—you can indulge in a high-quality self-loyly experience.

Garden Open-Air Bath

Enjoy the "Bihaku-sen" Beauty Hot Spring and explore various baths with unique atmospheres for a delightful on-site hot spring tour.

Hiranoya offers a variety of unique bathing experiences, including the "Garden Open-Air Bath Hina no Yu," the "Cave Bath," and the "Large Public Bath Kirara no Yu," allowing you to enjoy an onsen tour within the facility. The natural onsen of Mitani, renowned as "Bijin no Yu" (Beauty Hot Spring), is a rare alkaline simple spring with low salt and calcium content, commonly found in coastal areas. It contains various ions and is colorless, transparent, and gentle on the skin, earning it the name "Bihaku-sen" (Whitening Hot Spring). Additionally, our baths feature mineral-rich "rock bed stones" installed in the tubs. These enhance far-infrared effects and mineral absorption for increased perspiration and detoxification benefits. Immerse yourself in soothing waters that embrace your heart while enjoying a serene moment infused with natural warmth.
