Japanese Whiting

Sillago japonica

Japan's classic summer beach fish, taken on long casts with multi-hook rigs over open sand all around the country. It shares only a name with the European whiting, a cod-family fish of a completely different family — the shared word is coincidence. Its close relative the blue whiting (Sillago parvisquamis) is a rare Red List class-II protected species: learn the difference, release any suspected fish, and never target it.

Identifying features

Long, slender silvery body, pale golden-brown above and white below
Small mouth at the tip of a slightly pointed snout
Two dorsal fins close together, the first with sharp spines
No barbels and no dark blotches; the tail is slightly forked
The rare blue whiting looks very similar but is deeper-bodied and grows larger — it is protected (Red List class II), so release any large, deep-bodied sillago unharmed

Habits

Schools over clean sand, feeding on sandworms, small shrimp and crustaceans
Feeds mainly by day, picking food from the sand surface
Bites are famously light — a trembling nibble rather than a pull
Moves inshore in summer to spawn and slips to deeper water in winter
Often caught several at a time on multi-hook rigs once a school is found

Distribution

Regional coverage expanding

Where to find them

Kujukuri Beach surf, Chiba
Shichirigahama Beach, Kamakura, Kanagawa
Sandy beaches of the Miura Peninsula, Kanagawa

Where they live

Open sandy beaches and surf zonesShallow sandy bays and harbour mouthsSandy and sandy-mud bottom in about 15-100 ft (5-30 m)

How to catch them

Long-cast tenbin rig from the beach Shore

Rig: Surf rod with a tenbin (spread-arm) rig carrying 3-5 small hooks below a 3-5 oz casting sinker, cast well out over the sand

Bait/lure: Sandworm or ragworm pieces, threaded just onto each small hook

Key tip: Retrieve very slowly with pauses — whiting follow the moving bait and nibble; strike at the trembling bite.

Boat tenbin fishing over sand Boat

Rig: Short boat rod with a tenbin rig and 2-3 hooks above a 1-2 oz sinker, fished straight down over sandy bottom

Bait/lure: Sandworm pieces

Key tip: Let the rig rest on the bottom and lift gently; bites are tiny trembles, so watch the rod tip.
