Saltwater Β· Year-round migrant; winter fatty 'kan-buri' season Dec-Feb on the Sea of Japan side
Japanese Amberjack
Seriola quinqueradiata
Japan's iconic amberjack, famous as winter 'kan-buri' when fish fatten in the cold Sea of Japan. Its name changes with growth β wakashi, then inada, then warasa, and finally buri over about 80 cm; farmed juveniles are widely sold as hamachi. It is a distinct species, explicitly not the California yellowtail of the eastern Pacific.

Bait/lure: Metal jigs
Key tip: Work the jig with sharp lifts through the bait layer and be ready for a hit on the fall.
Rock and shore casting for warasa and buri Rock fishing
Rig: Long shore-game rod, large pencil or minnow lures cast from rocky headlands at dawn over current
Bait/lure: Topwater pencil and sinking minnow lures
Key tip: Fish first light when bait is pushed against the rocks; keep pressure on to stop the first run to reef.
