46. Denki-yu, Tokyo The sento from Perfect Days. Prices in photo. Lots of old-timers, friendly staff, no foreigners. Tattoos seem to be OK since there was a guy with full-body tattoos. Body wash and shampoo available (several large shared bottles for everyone). You recognize the places from the movie right away. The main bath is divided into 3 sections: one with gentle bubbles, one with jets, and one with stronger bubbles. The water is genuinely hot, clear, with a slight chlorine smell. It's a bit stuffy in the bath area. There's also a separate cold water bath.
