Schools push into sheltered harbours from autumn into early spring. They come in numbers and are full of small bones, so to many anglers their real value is as live bait for larger fish. Anything over 20 cm pulls hard in its own right.

How to catch it
Schools come to sabiki rigs off breakwaters in autumn. Use minced-shrimp chum and a rig with larger hooks; a casting sabiki reaches schools holding farther out.
Sabiki (bait-jig) fishing from a Breakwater / Pier
Pick a sabiki with larger hooks than the horse mackerel rigs use. These fish top 20 cm and fight hard enough to tear their own mouths if you swing them up. Keep a few alive in a bucket and you have live bait for flounder or seabass on the spot.
Waters: Southern Pacific coast, Seto Inland Sea, East China Sea & western Kyushu

Bony, and best vinegar-cured or fried. At kohada size it becomes a sushi topping, while the grown fish gives off a distinctive smell when grilled. Scoring the bones before frying makes it much easier to eat.
