Established in 1662. A historic onsen property in Hakone depicted in Utagawa Hiroshige's ukiyo-e.

In the spring of 2017, after about a year and a half of silence, a new chapter began. Founded in 1662. A history woven by Onsen waters—Edo, Meiji, Taisho, Showa, Heisei, Reiwa. Surrounded by magnificent nature, the scent of the waters lingers as artifacts from different eras and worlds add color and elegance to the Ryokan. Let your thoughts drift to the founder, Mannemon Matsuzaka. A long-established Ryokan beloved since the Edo period as an Onsen Accommodation—so renowned it even appears in ukiyo-e prints by Utagawa Hiroshige. From meetings between Takayoshi Kido and Takamori Saigo to a stay by Bunroku Shishi, leading figures of the Meiji era once gathered here. Since then, many guests—including members of the Imperial Family—have continued to visit. What captivates visitors is our rare, highly beneficial spring water found only here: it contains all three celebrated skin-beautifying types—sulfur springs, sulfate springs, and bicarbonate springs. Another reason is our abundant flow rate of 200 liters per minute. We adhere strictly to “100% free-flowing from the source,” with no added water, no heating adjustments, and no circulation. Moreover, the history of Hakone Ashinoyu is said to date back to the Nara period—more than 1,200 years ago. Now come and savor Hakone’s finest famed hot spring—a place cherished through time—and enjoy being part of its continuing story into the future.

  • This Accommodation has become more upscale in recent years and is now a bit of a splurge for me, so I visited this time to take advantage of a great deal. As always, the Onsen was wonderful, the meals were delicious, and the Room was spacious and very comfortable. I was also happy that you remembered my various requests from previous stays. Thank you to all the staff for your hospitality again—I’d love to visit again when I find another opportunity.

  • Once again, we thoroughly enjoyed the high-quality, free-flowing Onsen.In the quiet, peaceful atmosphere, we were able to relax at our leisure.We truly appreciated how accommodating you were with dietary restrictions.It is a little disappointing that the complimentary drinks service at dinner will end in September.

Location

Hakone Ashinoyu Onsen Matsuzakaya Honten is located at an elevation of about 870 meters, a quiet Onsen area surrounded by mountains. Ashinoyu, home to many historic sites dating back to the Kamakura period—such as stone Buddha statues and stone monuments—is one of the most historically rich areas in Hakone. Tokoan, where writers and artists gathered during the Edo period, is located within the grounds of Kumano Shrine next to our property. Ashinoyu lies along National Route 1, offering convenient access. Lake Ashi is about an 8-minute drive away.
