I stay in a capsule hotel in the Okachimachi area of Tokyo. Capsule Hotels are the cheapest accommodation in Japan. The place I stayed at cost 2,600 Yen ($30 USD) They are mainly for men and have a communal bathing area that has a hot spa. The capsule hotel I stayed at had free wi-fi, a safe and a television with two channels of Japanese porn, all naughty bits pixelated.
