It is said that Wright, who designed the YODOKO Guest House, took numerous hints from Japanese architecture and art. There are a number of places that give you the feeling of Japanese ideas inside the building, which looks nothing but Western from its outside appearance. New discoveries found during the three-year post-quake restoration work since 1995 are introduced here. Are these discoveries Wright's original works? Enjoy solving the mysteries with your imagination.

There are three Japanese-style rooms built next to each other with tatami mats on the third floor of the building. This is nothing particularly unique. From the building, however, clay walls (west side of Japanese-style rooms = a part of hall way) have been discovered in places where concrete is usually used in line with the overall building structure. Clay walls are a feature of Japanese architecture wherein clay is coated onto frames made by tied-together bamboo trees. Why are these walls there? In truth, these Japanese-style rooms were not in Wright's original design. These rooms were built in response to the owner, Yamamura's strong request, at the discretion of Wright's assistants, Arata Endo and Makoto Minami. Clay walls are strong even though they are relatively thin, thus rooms can be made bigger. They also have a role in protecting tatami mats from humidity.
