Higashimurayama, in the northwestern part of Tokyo Metropolis, is the birthplace of the beloved comedian Shimura Ken — 'the funniest man in Japan' whose Bakatono-sama sketch became one of the most celebrated comedic characters in Japanese television history — celebrated with a museum and commemorative plaza in the city whose local identity is proudly linked to Shimura's comedic legacy. Higashimurayama Onsen Tokyo draws on chloride-rich thermal waters from the geological resources of the northwestern Tokyo upland, providing warm restorative baths in a community whose comedic heritage, the Tama Lake Higashimurayama reservoir park, and the quiet suburban character create an appealingly human-scale and cheerful spa setting within the Tokyo Metropolis. The Shimura Ken Museum celebrating Japan's legendary comedian, the Higashimurayama Reservoir cycling and park walks, and the Musashino plateau agricultural remnants preserved in city parks create a pleasantly varied and cheerfully local spa destination in the northwestern reaches of Tokyo Metropolis.
Insider tip — Higashimurayama is a mid-sized Tokyo municipality best known for its Higashimurayama Reservoir, and its sento complements this green-water identity with saline thermal baths drawn from deep Kanto Plain sediments. The 41°C sodium-chloride water stimulates circulation and leaves a pleasant warmth on the skin that persists through the evening commute home on the Seibu Haijima Line. Facilities are clean and unpretentious, representative of the high standard Tokyo's municipal sento oversight enforces. The reservoir park just to the north makes an ideal pre-bath walk, especially in cherry blossom season.
