In Japan there are traditional Japanese crafting such as fittings, furniture, textile, etc., which are closely related to Japanese culture and life. The design of Japanese houses and their rooms is a very important problem to attract people. However, this design is not easy because people have different feelings. In order to deal with this problem, we have developed a Digital Traditional Japanese Crafting System(DTJCS) which provides a presentation space for traditional Japanese crafting. In this paper, we analyze the effect of room change of fittings to people?s feelings using the presentation system.
