Ubagamochiya Honten (Historical Sweet Rice Cake Shop)
Founded in 1569 (450+ years of history), this is the famous confectionery of Kusatsu-juku post town. Located at the famous fork between the Tokaido and Nakasendo highways, it has been loved by travelers since the Edo period. The 'ubagamochi' sweet rice cake was even depicted in Hiroshige's ukiyo-e print series 'Fifty-three Stations of the Tokaido.' A humble mochi made with local glutinous rice and smooth red bean paste — a beloved institution locals always visit when in Kusatsu. Tabelog 3.55/156 reviews.
