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.
