A long-established public bath founded in 1942
Tokyo Adachi City
"Hotta Yu" is a long-established public bath in Adachi Ward, Tokyo, founded in 1942. It underwent a major renovation in April 2022 and was reborn as a "learning from the past to create something new" space that blends a traditional miyazukuri-style exterior with a modern interior. The men’s bath features a medicinal herb sauna and an open-air cold plunge bath with a depth of 160 cm, among the deepest in Tokyo. The women’s bath offers Tokyo’s first wall löyly-style sauna, two types of cold plunge baths, and a newly installed medicinal bath, allowing both men and women to enjoy an overwhelmingly high-quality bathhouse experience. While admiring the tile artwork of Katsushika Hokusai, guests can spend a blissful moment in the gentle water unchanged since the previous generation and the latest sauna environment.
