Catch season

Prime from autumn into winter, when the baitfish are inshore. It is one of the largest fish reachable with a live bait from a pier, and hooking one is not something you forget.

About

A Japanese saying, hirame to the left and karei to the right, describes it well: hold it belly toward you and both eyes are on the left. Its mouth is larger than a righteye flounder's and each tooth is big and sharp. It reaches 1 m and 10 kg, and about nine tenths of an adult's diet is small fish, ambushed from the sand as it matches its colour to the bottom. The muscle along the fin base, engawa, is a delicacy.

How to catch it

Lure fishing from surf beaches is popular, casting minnows and jigs; from breakwaters, small live horse mackerel are drifted as bait. Spring and autumn are the peak seasons.

Nomase (live bait) fishing from a Sandy beach

Do not strike on the first tap. A flounder holds the bait before swallowing it, so wait ten to thirty seconds before lifting the rod; the Japanese saying puts the count at forty.

Nomase (live bait) fishing from a Breakwater / Pier

Use a small horse mackerel straight from your sabiki rig. Wet your hands before touching it, hook it quickly through the nose or back, and always net the fish rather than lifting it.

Jigging (metal jig) from a Sandy beach

Retrieve just off the bottom, letting the jig touch down periodically. Fish sit beside outflows and rip currents, so read the beach and cast at the changes. The teeth are sharp: remove hooks with pliers.
