When you open the door to your room take off your slippers before getting on to the TATAMI(straw mat floor).
Do not walk on the TATAMI with your slippers.
The TATAMI is always tread upon barefoot or with your socks on and you can squat down or just lie down on it.
On the wall side, there is a TOKONOMA (alcove).
You should remember that the TOKONOMA (alcove) is hanging scrolls and is not to be used as storeroom.
Also a YUKATA (robe) is provided for each person. Use this as a robe as well as a pajama and you can go out of your room in the YUKATA.
During cold periods there is a TANZEN (outer robe) to wear over the YUKATA. Always wear the TANZEN over the YUKATA.
