Overview:The Tobishima Kaido is a network of bridges linking seven Seto Inland Sea islands. The route starts in Shimo-kamagari near Kure in Hiroshima Prefecture and extends to Okamura in Ehime Prefecture. Osakishimo-jima's Mitarai district prospered as a port of call for Kitamaebune merchant ships, and retains the townscape from the Edo period. The island is also famous for its citrus farming, which dates back over 100 years. Britain Tom Miyagawa Coulton, who lives in Osakishimo-jima, takes us around the islands steeped in history.
