There is a linear settlement at the northwestern part of Rokuhara Fan, Iwate Prefecture. The settlement was constructed as a fort as a part of the strategic project of Date clan 400 years ago. There were 30 houses at that time, of which 7 families had remain and 22 houses are lived by their descendents at present. It is surprising that after 400 years they still have the old spirit of the clan and they show some friendship to the persons of Miyagi Prefecture.
