The reports of the 1923 Kanto Earthquake by the Geological Survey of Japan include the data of the number of damaged wooden houses not only on municipalities but also on village sections. We added these data to the current data, and obtained a detailed seismic intensity map of Saitama Prefecture. The map indicates that the seismic intensities in Saitama Prefecture were strongly influenced by the ground condition of each point. The seismic intensity maps estimated for the same kind of earthquake by the government of the Saitama Prefecture (1982, 1998) show many characters different from the actual intensity distribution, because the government maps were made mainly based on the results of the calculated seismic intensities from the assumed earthquake fault. The map in the present study based on the past experiences should be more reliable and must be useful for predicting seismic intensity from future earthquakes, because the calculation process of seismic intensities usually needs many apriori assumptions
