How to catch it
Kit for this fish
Shore jigging kit ・ Kit total ¥40,000–100,000
- Shore jigging rod, 10 ft, MHLong and powerful enough to cast 40-60 g jigs and to absorb the runs of a hooked jack. ¥12,000–40,000AdFind on AmazonFind on Rakuten
- Spinning reel, size 4000-5000For shore jigging. A smooth drag under a running fish matters more than anything here, so this is not the place to economise. ¥10,000–35,000AdFind on AmazonFind on Rakuten
- PE braid, 1.5-2 gouFor shore jigging: the compromise between casting distance and strength. ¥2,000–6,000AdFind on AmazonFind on Rakuten
- Fluorocarbon leaderThe clear line tied to the end of the braid. It resists abrasion and is less visible, protecting the braid from rock and teeth. ¥800–3,000AdFind on AmazonFind on Rakuten
- Metal jig, 30-60 gThe mainstay of shore jigging. Carry the same shape in several weights and switch with wind and current. ¥600–2,500AdFind on AmazonFind on Rakuten
- Landing net with 5 m handlePiers sit high above the water and heavy fish break off if you lift them. Having one changes what you land. ¥4,000–20,000AdFind on AmazonFind on Rakuten
- Fishing pliers / hook removerEssential protection from venomous spines and sharp teeth. Most injuries happen when someone unhooks a fish bare-handed. ¥800–4,000AdFind on AmazonFind on Rakuten
- Knife and spike for bleeding fishWhat turns a caught fish into good food; bleeding it changes the taste. See the column "Killing and carrying your catch" for how to use them. ¥1,000–6,000AdFind on AmazonFind on Rakuten
- Cool box, 15-20 LFor carrying fish home cold. Take plenty of ice; in summer a poorly insulated box is not fit for the job. ¥4,000–25,000AdFind on AmazonFind on Rakuten
- Life jacket, adult (Japan Craft Inspection approved)The first thing to buy, and worn on piers, rocks and boats alike. Boat fishing requires the government-approved type marked with the cherry-blossom stamp. ¥5,000–20,000AdFind on AmazonFind on Rakuten
- Studded or felt-soled bootsOrdinary shoes slip on rock and tetrapods. Falls are the most common cause of accidents, so these are mandatory for rocky shores. ¥4,000–15,000AdFind on AmazonFind on Rakuten
You will often be on rocks or the tip of a breakwater at dawn, where safety gear matters more than results. Do not go alone.
