Fish species in Japan

Largehead hairtail

タチウオ · tachiuo
Trichiurus lepturus

Its ribbon-shaped silver body is driven by a long dorsal fin. Hairtail may hover head-up before moving horizontally to chase prey.

Habitat and season

Coastal and offshore midwater; fish may rise in low light.

Months are a broad guide, not a current catch forecast. Region, water temperature and local closures can change the season.

Tenya is a weighted head with a large hook, usually baited with a whole sardine. Boat anglers work it through the depth called by the skipper.

Metal jigs are worked below a boat through the depth occupied by predators.

A float shows bites while suspending the bait at a chosen depth. Adjusting the float stop changes the feeding layer.

A baited weighted hook is retrieved from shore for hairtail, often around dusk.

Learn the sequence used on Japanese hairtail boats without confusing a small preliminary tap with a committed take.
