Our family lived in Koi, which is west of the City of Hiroshima and 2.5km from the center of the destruc-tive blast from the atomic bomb. Behind our home was a hill named Chausu-yama. In older times, this area was known as Hirabara. On this hill the Koi clan built and resided in the Hirabara Castle during the Kamakura period and through the Sengoku period, almost four hundred years. From our house we could see the Seto Inland Sea (Setonaikai) and Hiroshima. The valley of januki lay down the hill from our home.
