Okinawa de Suki ni Natta Ko ga Hougen Sugite Tsura Sugiru (1970)

I, Teruaki Nakamura, transferred to Okinawa and fell in love with a girl… but I can't understand her dialect. Thankfully, Higa-san is always helping me out with translations. A cross-cultural romance that's a wee-bit different begins on the southern island!
