Upon entering one will most likely find themselves in the agri-kamachi which is a small room where one takes off their shoes before entering, as is Japanese custom. Slippers are generally supplied for indoor use. Doors in ryokans are the sliding paper doors called shoji. The flooring of your room will be made of straw or reed matting known as tatami. Soft bedding known as futons are layed out on the floor and are often rolled up and put in oshiire which are cupboards specially designated for the futons. Note that traditional ryokans are not likely to have modern appliances. Rooms generally also have a view of traditional Japanese gardens.
Also in your room you will find a low wooden table with zabuton or sitting cushions. A menu will be provided listing traditional Japanese foods that are available and the food will be brought to your room. This way you can literally get a taste of Japanese tradition. Enjoy!
Hot springs and Baths
A custom derived from the tōji-ba is to have a hot spring mineral bath called onsen or non-mineral, deep, warm baths called ofuro. While some ryokans may supply an ordinary private bathroom or even your own private onsen or ofuro, many will have communal onsen or ofuro. These are usually gender separated. If the ryokan only has one bath they may have alternative hours for each.
These baths are very good for your health and are said to be very enjoyable. There is an etiquette that is best to be followed. For more info press on the following link.
