For the approximately 1,100 residents of Kakeroma Island in southern Japan, water taxis that travel to Amami Oshima, a nearby larger island, are a vital mode of transport for going shopping or to work. Among the people using these boats during 3 days in late March were a woman who had stocked up at a supermarket; a family who had moved here from Tokyo; and a teacher being transferred after completing his post at a school with 18 students. We explored the role these boats play in daily life here and in keeping community ties strong.
