OKARI-YA was the private villa of DATE-family, the lord of SENDAI-HAN in EDO era. MATSUSHIMA and SHIOGAMA were the resorts of DATE-family and there was a OKARI-YA in each place. This report intends to introduce and analyze these OKARI-YAs. Through the examination of preserved buildings and historical materials, the following results are ascertained : 1) In MATSUSHIMA, OKARI-YA continued to exist throughout the EDO era. In SHIOGAMA, OKARI-YA was removed in 1734. Instead of OKARI-YA, OYASUMI-JOs (the house for rest) were built, attaching themselves to the influential stores. 2) Both OKARI-YA and OYASUMI-JO had a set of two or three rooms for staying or resting of the lord. 3) OKARI-YA differed from OYASUMI-JO in point of building stile, site, superintendent and so on.
