Sento — Japan's Neighborhood Public Bathhouses
Murals of Mount Fuji, a shared soak with strangers, and a fading tradition — how sento differ from onsen, and the etiquette of a public bath.
Long before most homes had their own bath, neighborhoods relied on 銭湯 (sento) — public bathhouses charging a small fixed fee, open to anyone. Unlike an onsen, a sento's water isn't naturally heated hot-spring water; it's just hot water, but the ritual and etiquette are shared with onsen culture, and many people still visit regularly rather than bathing at home.

Why murals of Mount Fuji are everywhere
Many older sento have a huge painted mural of 富士山 (Mt. Fuji) on the wall above the bath — a tradition said to date back to a single Tokyo sento owner in 1912 who wanted to give city bathers a view of nature. It became so popular that painting a Fuji mural turned into a near-standard feature of sento nationwide.

A tradition in decline, and a hobby reviving it
As home baths became standard, the number of sento in Japan has shrunk dramatically over the decades, and many now double as community and tourist attractions rather than daily necessities. A growing hobby called 銭湯巡り (sento-meguri, “sento hopping”) has emerged among enthusiasts collecting visits to different bathhouses, each with its own mural, tilework, and regulars.
