For my rate, the lowest, it is a single room measuring between 14 and 17 square meters. I have a 14. That's about 3.5 x 5. The first 2 meters in length of 5 is entry hall/small closet and bath. The room itself has a single bed against the wall, and along the other wall is a long desk with TV and coffee maker on it, a refrigerator below. On the bed side there is the length of the bed plus space to slide my suitcase at the end of it on the floor. No possibility of unpacking. Between the bed and desk there is space to squeeze through if someone is sitting in the (one) chair. For an extra Yen 1,000 a night I get three more square meters. For an extra Yen 2,000 a night I get 7 more square meters, which then includes walking space, space for the suitcase, and a small table and additional chair. Closet and bathroom are the same - small but adequate. This is okay, but I think I would up size one next time.
