You can feel the traditional Japanese style rooms ( washitsu) which comes with a unique interior design including tatami (japanese floormats),fusuma and shouji(sliding door for partition made of washi,japanese paper)

Tatami(japanese floormats)

Tatami mats are thick, woven straw mats that measure about one by two meters in size. Originally a luxury that only the wealthy could afford, tatami gradually became more common and can now be found in virtually all traditional Japanese homes. Tatami mats have been so integral to Japanese homes, that the size of rooms in Japan is commonly measured by the number of mats that would fit it, e.g. an 8-mat room. Note that footwear - even slippers - should be removed before stepping onto tatami.

Fusuma(japanese sliding doors)

Fusuma are sliding doors made up of wooden frames covered in thick, opaque paper. The doors are typically used between adjoining rooms akin to large removable walls, allowing one to partition off areas or open up space as needed. Historically, fusuma have been the canvases of famous painters, and some elaborately painted examples can be seen at templesand palaces.

Shoji(japanese translucent sliding doors)

Another type of sliding door or partition are shoji, which are made up of wooden lattices covered in translucent paper. Shoji are typically found along the perimeter of the building, allowing light to filter in. Some shoji doors incorporate sliding panels that move up and down like small windows to allow more light or air to enter the room. 

Ranma (transoms)
Ranma are wooden transoms that are typically found above fusuma in traditional Japanese style rooms. They may be intricately designed and curved, and serve to allow air and light to move between rooms.
