Research Abstract	One of the main factors of urban heat island phenomena is surface temperature, and the surface temperature is mainly affected by the spatial geometry and material. The city of Edo, fore past Tokyo, had been a metropolis in the late Edo period, and the townsmen's living areas in the city were totally different from present Tokyo in spatial geometry and material. In the previous study, the summer thermal environment of the block(=Machiyashiki) in this residential area was studied using numerical simulation. Urban heat island phenomena have become serious problems not only in summer but also in winter. Concerning the location of the target site, the influence of wind from the Edo bay(=Tokyo bay) was important as well. In this paper, thermal environment in the Edo townsmen's residential area in two seasons, summer and winter, was evaluated from surface temperature and sensible heat flux, which were concerned the influence of airflow using CFD.
