 In this study, the summer thermal environment in the living areas of Machiyashiki (= a residential city block) in Edo, early modern Tokyo, was evaluated considering the residents' living activities. First, the ways to deal residents' environmental adjustment behavior on a summer day with the numerical simulation were considered, and the spraying of water at nighttime and the setting out of benches in the streets and alleys were selected. Second, the distribution of surface temperature in the target site on a clear summer day was calculated by numerical simulation. Last, residents' living spaces in the target site were evaluated from the remainder of MRT (Mean Radiant Temperature) and air temperature. The results showed that MRT was generally lower than air temperature in the residents' living spaces, suggesting that residents in the Machiyashiki were able to select cooler living spaces.
