The eel is a migratory fish that descends to the sea to spawn. After living in the river for 6 to 8 years, mature individuals swim down the river into the sea in the fall and winter to spawn in the depths of the ocean. After the eggs hatch, they drift with the ocean currents and become transparent "eel threads" in the estuary through the metamorphosis of the willow leaf fish stage, and then grow up the river with the rising tide. They are carnivorous, feeding on small fish and benthic organisms.

The eel can be grilled, boiled in soup, or braised. It is often processed and made into kabayaki eel. It is mainly farmed, and wild species are rare.
