When coming to Japan, there’s a wealth of things to do and see–even just staying within the Tokyo city limits, you’d be hard pressed to enjoy everything available in a week. On the other hand, if you just stick with the big sightseeing spots, you’ll be both crushed by crowds and probably bored in a few days. This has left a lot of overseas tourists with time–and incentive–to look for new or unique activities.
One of the things apparently gaining popularity is sento, or public bathhouses. While not quite as much fun as hanging out in hot springs in the mountains with monkeys, sento still provide a fun and different activity for anyone just looking to relax. The warm waters are especially welcome after a few days running around Tokyo! But you might want to check this handy guide before you head out for a soak in order to avoid annoying other bathers.
