On tiny Oge Island in the Inland Sea off Imabari, Ehime Prefecture, Yoichi Manabe, 41, a member of the Aishin hunting club in Niihama, hurriedly carried the carcass of a 70-kg wild boar to a breakwater and plunged it into the sea.

After a while, he swiftly removed its internal organs before plunging the carcass back into the water. "Draining the blood quickly is a cardinal rule for enjoying your meal. It should be done while the heart is still beating, and the body should be cooled immediately," he said of a practice performed by game hunters worldwide to avoid becoming sick.

Manabe had killed two boars that day after people on the island asked him to rid them of the animals that were running rampant in their fields. He occasionally goes to Hokkaido to hunt deer. That evening, Manabe and his club colleagues dined on grilled boar and hot pots.
