One of the many faded relics that crowd around Asakusa’s famous Sensoji, this bathhouse offers a singularly grotty experience at an inflated price. Only the early opening time makes Asakusa Kannon Onsen worth considering; tourists thrill at the archaic facilities, coated in a patina of dirt, but most locals give the place a wide berth. Though the waters are reportedly good for rheumatism and nervous disorders, the chlorine tablets lurking at the bottom of the tubs are more than a little off-putting.
UPDATE: Asakusa Kannon Onsen closed for good in summer 2016.
