While I can certainly understand that specific customs and accommodations do differ in Japan vs. other places, I was shocked by the fact that the “room” was so small (barely enough room to turn around, let alone lie down) and completely lacked a door or any other way to meaningfully secure my belongings. I wound up lugging all of my valuables with me everywhere I went in Tokyo for fear that I might be robbed if I left them in the hotel. At night, I lay awake tossing and turning, fearful that a stranger could enter my room at any time. Not recommended, despite the reputation for safety that Japan as a whole deservedly enjoys.
