Izumi Ishii is a reformed Japanese dolphin hunter from the town of Futo - Shizuoka prefecture, a town with a long history of dolphin drive hunting. Ishii San was a 6th generation dolphin hunter after his grandfather and father. Seeing tears in a dolphin he killed, he decided to stop hunting and launched his whale and dolphin watching business in 2002. Futo’s dolphin hunting stopped since 2005 as a direct result of his action. Dolphin hunters say the presence of his watching business with his beloved fishing boat Kokaimaru makes it impossible for them to continue the commercial killing.
Ishii San works tirelessly to convince the public, the dolphin drive hunters in Japan and the Japanese government that the dolphin drive hunting is not in tune with the rest of the world and a total ban is the only answer. He runs a symbolic dolphin & whale watching business with his boat Kokaimaru to demonstrate that the watching is the only alternative to the brutal killing of dolphins.
