Hakone Sengokuhara Prince Hotel (formerly Hotel Ohakone), which opened in 1992, has undergone its first renovation. concept design concept is "relaxation x sparkle x intellect." The interior, concept design with "Hakone marquetry" as a motif, features a luxurious restaurant, an open-air bath where guests can experience the magnificent nature, and two guest room buildings themed around "kodachi" (the impression of the beautiful trees of Hakone Mountain) and "Hikari" (angelica blooming on the plateau and the glittering pampas grass of Sengokuhara), creating a space where guests can feel both nature and intellect. In this project, which has been reborn as a unique modern hot spring resort that resonates with nature in Hakone, one of Japan's leading hot spring areas, our company assisted with everything from the basic concept to design, layout, production, and construction.
