I am trying to locate my moms youngest sister and her family. Shigeko and her husband Izumi Yoshie. Their house was a little ways from the station and their house was surrounded on three sides with a vineyard. I believe they rented this house out after buying another one. They have two sons Chihero and Tomaki (not sure if spelling is correct. Chihiro is now married and not sure where he lives. Uncle Izumi worked in a place where special rocks were found (some were bluish purple and looked like they had crystals in them). Any help would be appreciated.
