From Great Hanshin-Awaji Earthquake happened in 1995, Japanese temporary housing for natural disaster was supposed to be prefabricated light-weight steel building. However, since the Great East Japan Earthquake in 2011, timber temporary housings have been provided. In Japan, the production system of timber houses has been developed drastically after the introduction of so called ‘pre-cut’, a kind of prefabrication system. Nowadays even small local construction company can provide a simple timber housing in about 1.5 month. For the 2016 Kumamoto Earthquake 683 out of 4,303 units were made of timber. Those timber housing foundations were made of reinforced concrete, which is contrary to the conventional timber pile one and was intentionally chosen for the future permanent use. Temporary housing is determined by law to be demolished two years later. Therefore, people who cannot reconstruct their houses by themselves within that two years is forced to move to ‘disaster public housing’ which is also build by the government. To change the living place many times is big mental burden for victims and construction costs and resources are also wasteful. Therefore, we think the diversion of timber temporary housing is effective for those issues. We interviewed the officers who were in charge of temporary housing in Kumamoto pref. and municipalities in the area. We summarize the points of this paper below.  Conditions that the municipalities chose the timber temporary housing (Chapter 3, 4) (1) In Kumamoto case, it was easy to choose the timber in region which population density of habitable area is low and damage was little. (2) Each municipality had gradually recognized the merit of timber house as time went on. Table. 1 shows that the ratio of light-weight steel building supply was high in the beginning, but the ratio of timber one became higher as the construction ended. (3) Timber housing is not standardized but has high adaptability. Barrier-free temporary housing was made of timber (Photo 3). And light-weight steel prefabricated one needs wide road to bring construction machinery in. (4) Some municipalities answered it will take more time to provide the timber housings because of not only construction period but also time for consultation with the prefecture.  Conditions that the timber temporary housing can be diverted to the permanent housing (Chapter 6, 7) (1) In Kumamoto case, it was easy to divert the timber temporary housings constructed in small public land such as former public housing site, unused public land, park and square. (2) If the municipality can prepare the alternative land, they will get more extend possibilities to divert the timber temporary housings built in playing field and park based on City Parks Act. (3) When the timber temporary housing is diverted in private land, the municipality need to negotiate the land owner. Especially in case farmland, they should consider that it will take longer period and will cost a lot to obtain the permission of diversion. (4) Though the timber temporary housings in Kumamoto were diverted in the same way, we can extend the possibility of timber temporary housings by considering other utilizations after diversion according to each municipality's conditions.
