Unbothered by the rough water, fishermen of Tosa Province cast their lines. In the foreground, the process can be seen up close. To the far left and right, men throw smaller fish from the buckets on board to lure the bonito. Two of the fishermen hoist their catch into the boat while three fish gather near the hull. Bonito was a local specialty (meibutsu) and important export for Tosa Province. The fishermen here chose to use poles rather than nets to minimize the stress and damage to the fish. It was thought that this gentle approach would optimize the fishes’ flavor. The former Tosa Province spanned southern Shikoku, corresponding with modern Kochi Prefecture.
