Giant Trevally, or GT, is one of the most satisfying fish to land at Kaiji No Ri, and you do not need a boat to catch one. I do it from the shore at the Torii No Koto spot, casting into the water beside the rocks, and it works consistently once your rig is right. The GT in the photo below is one I pulled from exactly this spot: 110 cm and just over 25 kg. This guide is the exact method I use, the gear, the bait, and where to cast, so you can go straight to a big fish instead of guessing.
Where to Catch Giant Trevally at Kaiji No Ri
Kaiji No Ri is a Japanese island map with warm, reef-rich water, and the Giant Trevally is one of its headline predators. Make sure you have a valid license for the map first. I run the Advanced license here, and fishing without one just wastes coins on fines. Once you are on the island, you do not need to launch the boat for this fish. The GT is well within reach from the shore, which makes this one of the cheapest big-fish catches on the map.
The Spot: Torii No Koto
Go to the Torii No Koto spot first. It is a shore position, so you fish it on foot, standing beside the rocks with the open water in front of you. This is the whole trick to catching GT here cheaply and reliably: you do not travel out by boat, you just walk to the rocks and cast. Set up right at the edge of the water next to the boulders and you are in the zone.
Look out from the shore and you will see two large rocks standing out of the water in front of you. That is your target. Cast toward those two boulders and let the rig settle on the bottom near them, because that is where the GT holds and hunts. Do not just fire it out into open water. The rocks are the structure that concentrates the fish, so every cast should be aimed at them.
The Setup for Giant Trevally
GT hits hard and pulls harder, so the whole rig is built around not being undergunned. Here is exactly what I use.
| Component | What to Use |
|---|---|
| Rod | A strong bottom rod that can lift 50 kg or more |
| Method | Bottom fishing from the shore |
| Hook | #7/0 up to #11/0 |
| Sinker | 250 g minimum, but do not go too heavy |
| Bait | Large Fish Strips or Medium Fish Strips |
The rod is the part you cannot cheap out on. You want a bottom rod with enough lifting power to handle 50 kg and up, because a big GT will test weaker gear and you do not want to lose the fish at the rocks. On the hook, anywhere from #7/0 to #11/0 works well with the fish strips, so pick within that range based on what you have. For the sinker, 250 g is the floor. You need enough weight to hold bottom and cast to the rocks, but going too heavy hurts your feel and casting, so stay sensible rather than loading up.
Bait: Fish Strips
The bait is simple: Large Fish Strips or Medium Fish Strips. The GT is a predator that wants a chunk of fish, and both work, so use whichever you have or can afford. You can pick them up in the shop, and stocking a few packs before you head to the spot means you are not cutting a session short when you run out. Rebait as needed and keep a fresh strip on the hook.
How to Fish It
Put it all together and the routine is short. Stand beside the rocks at Torii No Koto, bait up with a fish strip, and cast toward the two big boulders in front. Let the sinker take the rig to the bottom and hold it there, then wait for the GT to find it. When one takes, expect a strong, fast run, so keep your drag controlled and do not try to muscle it straight in, especially near the rocks where a big fish can find something to break you off on. Fight it steady, bring it in, and you have your Giant Trevally.
Watch the fish activity graph on the map screen and fish the peak windows rather than the flat, dead parts of the day. Same rig, better timing, more bites.
Common Mistakes
Taking the boat out when you do not need to. The GT is reachable from the shore at Torii No Koto, so launching the boat just costs you time and effort for no gain.
Casting into open water instead of at the rocks. The two boulders are the structure that holds the fish. A cast that lands away from them is a wasted cast.
Using a weak rod. A big GT will beat gear that cannot lift its weight, and losing a 25 kg fish at the rocks stings. Bring a bottom rod rated for 50 kg and up.
Overloading the sinker. You need 250 g to hold and reach the rocks, but piling on more weight only hurts your feel and casting. Keep it at a sensible minimum.
Frequently Asked Questions
Where do you catch Giant Trevally at Kaiji No Ri?
Fish the Torii No Koto shore spot. Stand beside the rocks and cast toward the two large boulders in the water in front of you. You do not need a boat, and that is where the GT holds and feeds.

Large Fish Strips or Medium Fish Strips. The GT is a predator that takes a chunk of fish on the bottom, and both baits work, so use whichever you have.
What rod and rig do you need for GT at Kaiji No Ri?
Use a strong bottom rod that can lift 50 kg or more, a hook between #7/0 and #11/0, and a sinker of at least 250 g without going too heavy. Fish it as a bottom rig from the shore.
Do you need a boat to catch Giant Trevally at Kaiji No Ri?
No. The Giant Trevally is catchable from the shore at Torii No Koto. Just walk to the rocks and cast toward the two boulders, which saves you the time and effort of taking the boat out.
How big does the Giant Trevally get at Kaiji No Ri?
They get big and fight hard. The one I landed from Torii No Koto measured 110 cm and weighed just over 25 kg, which is why you want a rod with the lifting power to handle a fish of that size near the rocks.
