We carried out a work shop combined "problem inspection map" and "KJ method" in Niigata Pref. Tookamachi-shi Gejo-chiku with violent population decrease and aging in a heavy snowfall area. In this paper, we tidied the problems, the ideal and also the solutions of "aging" obtained by this result, and we carried out a study about the one.
As a result, the case like the following became obvious.
1) An aging rate of Gejo-chiku with heavy snowfall and depopulation reaches to 24.1% and this area is ultra aged society.
2) Aging rates of 25 towns of Gejo-chiku are 16.1-44.3% and the difference inside the area is very big.
3) The aged ratio of the families who live in Gejo-chiku is 63.9% and the most of them are living together with parents and children. However, we are expected that gradu-ally the aged couple families increase from now on.
4) Making of the age's life worth living is extremely important in order that the aged overcome aged society.
5) The healthy constant aged request the system and environment inducing the development of the rich and comfortable area life.
6) It is very inportant because an area is remaining and live on that building community by inhabitants is gone expanding.

Survey of administrative guidances for loads on buildings were carried out. The author picked up its results consisting to snow loads and compared that with AIJ recommendations for loads on buildings. The values of snow depths established in the local ordinances were relatively smaller than those of mean recurrence interval of 100 years which are observed at observatories belonging to the Japan Meteorological Agency. The snow depths estimated with altitude and sea ratio were verified at the each point of local government office. In snowy areas, the values showed the same characteristics with those of observation points. Though, in some areas especially in Ohita prefecture, reexaminations on the regression coefficients in the AIJ recommendation would be necessary.
