Slippers are worn inside, except on tatami matting. So bring thick socks if you are travelling in winter. The toilet is usually Japanese style, which means that the toilet bowl is not the sit-down type but the squatting type. You squat, facing the hooded end. Special slippers are usually provided for use only in the toilet cubicles, hence don t wear them anywhere else.
Toilets are very clean in Japan.
When taking a bath If you are going into a communal bath, you must first disrobe in an anteroom, placing your robe and underclothing in a basket or compartment. You will be given a towel to cover yourself. The same towel is also used for scrubbing and drying your body. Fill a bath pan with water and pour it over your body. If there are no faucets, use a bath pan to scoop water from the bath.
