Takara-yu is a distinguished sento in northern Tokyo, with a garden that looks like it’s taken straight out of a traditional hot spring Japanese inn. Built in 1927, the sento is known among Japanese anime fans as the setting for Kamen Rider, yet it’s the veranda which draws the crowds.
The Japanese garden is accessible from the reception area or from the men’s changing room. On Wednesdays, the areas switch, so anyone on the female side hoping to get some gaikiyoku (outside bathing) should visit mid-week.
