Hatsuhana Soba

PRESERVE Selected

Founded 1934 in Hakone-Yumoto, Hatsuhana invented jinenjo (wild yam) soba bound with grated yam and egg instead of water in the postwar years — the originator of a dish now copied across Japan, served in an old riverside building.

A near-century-old soba institution that created Hakone's signature noodle; a heritage name Hakone families have trusted for generations.
