Many human skeletal remains have been excavated up to the present at archeological sites of the early modern Edo period (1603-1867 A.D.). Neverthelss, data on teeth from each site of the Edo period have rarely been reported. Therefore, the data on the maxillary permanent teeth of 166 male, 27 female, and 18 unknown-sex skulls from a site of the Edo period, i.e., Fukagawa-Unkoin Temple, Tokyo, were presented here as part of a future data base on the population history within the Japanese archipelago. Means and standard deviations were estimated for the mesiodistal and buccolingual crown diameters as well as for the mesiodistal neck diameters of all the maxillary teeth, and for the depths of lingual fossa of the maxillary incisors. As for non-metric tooth crown characters such as shoveling, the Carabelli trait, etc., the frequencies of four expressivities for each character were calculated. A preliminary analysis by the use of Mahalanobis' D^2 distance based on nine tooth crown diameters shows that the Fukagawa-Unkoin sample is closest to the pooled sample of the Edo period from the Kanto district among 35 comparative samples from prehistoric, historic, and modern East Asians. Although this result seems reasonable, there are a few problems in processing data which are originally related with small sample size. Therefore, in order to reconstruct the exact interrelations between sub-populations within the Japanese archipelago, much larger amount of detailed data for each site should further be accumulated.
