KAYAGOMORI is a space for withdrawing into one’s shell and landscape diary to refresh oneself in mind. The user in KAYAGOMORI will be able to interact with himself and the landscape. The content name comes from Kaya: Japanese mosquito net and Hikikomori: a social problem in Japan. The structure of KAYAGOMORI is a cubic frame with layered fabrics which is called “KAYA SCREENS”. User can control the clarity of KAYA SCREEN freely. KAYA SCREEN enables the private time with controlling the level of interruption from outside. The main function of KAYAGOMORI is “landscape diary”. KAYAGOMORI memorize the landscapes that the user had experienced in past time, and it projects them on KAYASCREENS. For the future, KAYAGOMORI will be located everywhere: in one’s yard or roof, sightseeing spots and the middle of a vast wilderness. The user can interact with himself in the past time by using “landscape diary” without using Weblog, BBS, analog diary and other literature tools.
