Palace Japan

Palace Japan opened in early 2011, not far from Minami-Senju Station in the east of Tokyo, and seems to be catering towards the backpacking community. It's cheap and still in good nick, with all the necessary extras (read: free WiFi). Guests share a coin laundry, a small kitchen and shower rooms, and the whole place is designed to be barrier free – something that's still rare in Tokyo. Singles cost ¥3,500, and you can get a dorm bunk for ¥2,900.
