A lot of bamboo is used in soan tea rooms. With its qualities of lightness and elegance it has been used in architecture since ancient times. As is seen in ordinary houses, bamboo is mostly used in tea rooms for lattice windows, and for the rafters and laths of ceilings.

Bamboo somehow gives a feeling of furyu 'refined elegance', but if it is used too conspicuously, the appearance of the room as a whole can lose its sharpness and stillness.
A lot of bamboo is also used where it cannot be seen, inside walls. Split bamboo is used as part of the walls' inner support. Whether it is sugi (Japan cedar) or bamboo, Kyoto has, from long ago been blessed with high quality materials.
