Tendo Onsen is a celebrated hot spring in Tendo city, Yamagata Prefecture, a city with two distinctive claims to fame: as the capital of Japan's shogi (Japanese chess) board game production — responsible for over 90% of the country's shogi pieces — and as the host of the renowned Ningen Shogi (Human Chess) festival, held each spring when elaborately costumed samurai actors are moved across a giant outdoor shogi board like live chess pieces. The siliceous thermal waters provide smooth, skin-softening bathing and relaxation, complementing the city's playful and culturally idiosyncratic character. The surrounding Yamagata landscape of rice paddies, cherry orchards, and the hot spring district's traditional ryokan inns create a warmly convivial atmosphere in this proudly distinctive Yamagata city.

Insider tip — Tendo Onsen is set in the shogi-piece capital of Japan, where Yamagata's gentle alkaline bicarbonate spring surfaces at 40°C amid cherry blossom avenues. Spring visits coincide with the Tendo Ningen Shogi festival, when local citizens dress as chess pieces on a giant outdoor board. The clear, skin-softening water suits all bathers, from children to the elderly, across a range of public and private bath facilities. Tendo's compact hot spring district rewards an unhurried afternoon of soaking and exploring.
