Jakotsuyu Bathhouse (CLOSED)

Though it's five minutes' walk from Asakusa Station, on an alley just off Kokusai-dori, Jakotsuyu tends not to get much tourist traffic – which is all the more surprising when you consider that it's been going since the Edo period. The owners have given the place a few overhauls since then, and hardcore shitamachi geeks may be disappointed by the functional, modern interior. A painting of Mt. Fuji looms over the indoor bathing area, leading to a rock-lined outdoor rotenburo. If you've come without the necessary toiletries, there are sets available for ¥140, including a towel.
