Japanese Barracuda (Kamasu): The First Sign of Autumn on the Beach

minagiman

September on a Japanese beach: there is bait everywhere, you are throwing yellowtail lures, and all you get is a stream of small, sharp taps. Eventually you land one – a long, thin silver fish with an underslung jaw full of teeth. A barracuda. Kamasu.

If you came for yellowtail, the natural reaction is “you again”. But on my coast, barracuda turning up actually tells you something important about the season. This is how to catch them, and what they mean.

On Enshunada, barracuda arrive first

Going back through my own catch reports, one thing was consistent: in mid-September, yellowtail have not properly arrived yet – barracuda come in first. On 10 September 2024 my notes say “plenty of bait, barracuda in huge numbers”. I went for yellowtail and caught barracuda.

Put simply, autumn on this coast runs in a sequence:

When	Who arrives
Early to mid September	Barracuda (kamasu)
Early October	Ribbonfish (tachiuo)
Mid to late October	Yellowtail season opens

Barracuda appearing means bait is moving inshore. Roughly a month later, the yellowtail tend to follow. Ribbonfish are the closer signal – see ribbonfish (tachiuo) and when yellowtail arrive.

What kind of fish it is

A long thin body, a protruding lower jaw, and sharp teeth. As it looks, it is a pure fish-eater that runs down schools of small baitfish.

Schools. Catch one and there are almost certainly more around you.
Moves fast. Non-stop bites one minute, gone the next – that happens all the time.
Drawn to light. Around harbour lights is a classic spot.
Most active at dawn and dusk. They bite in daylight too, but react more clearly in low light.

How to catch them: small, fast, light

Fish for them with yellowtail lures and you mostly will not catch them. Barracuda have small mouths, so dropping lure size comes first.

Item	Guide
Lure size	About 5-9 cm. Yellowtail lures over 10 cm are usually too big
Weight	10-30 g. Around 20 g is easiest on a beach where you still need distance
Colour	Silver as default. Pink or gold at dawn and dusk, glow when dark
Retrieve	Quick. A fast straight retrieve with the odd change of pace

Lure types that work

Small metal jigs – cast well and suit fast retrieves. The quickest way in.
Small minnows and sinking pencils – strong when the school is near the surface.
Jig head and soft plastic – when they are fussy. The downside: the teeth chew through plastics.
Metal vibration lures – to check whether you are running at the wrong depth.

The general jig advice is in my metal jig guide, but for barracuda specifically, just remember: one size smaller.

Finding the school

Barracuda roam, so this is about catching the moment they are in front of you rather than finding the spot they live in.

Bait jumping – small fish breaking the surface means something is underneath.
Bites but no hook-ups – barracuda are nipping at the back of the lure. Size down and they will stick.
Caught one? Repeat the same line. There is a school; go for the next one.
Bites stopped? The school moved. Do not wait – walk a little and search again.

Where to stand is the same question as for any beach fish – see how to read a surf beach.

Watch the teeth – they quietly wreck your leader

Barracuda teeth are sharp. They rarely cut you off in one go the way Spanish mackerel do, but you will often find the leader has gone rough without noticing.

After every fish, run the leader through your fingers.
If it feels rough, re-tie it on the spot.
Soft plastics get shredded. On a busy day, carry plenty of spares.

Re-tying eats fishing time, so leave a longer leader to start with – more in knots on the beach.

If you keep them, freshness is everything

Barracuda flesh is soft and spoils fast. They do not need the full bleeding treatment you would give a yellowtail, but whether you kill and chill them straight away makes a clear difference to the taste.

Into a cooler with ice as soon as they are caught.
You can catch a lot of them, so bring more cooler space than you think.
For sashimi, eat them the same day. After that they are better grilled or dried.

The basics of killing and chilling are in how to bleed and chill a fish on the beach.

Common questions

If barracuda are biting, does that mean no yellowtail?

On a given day they can compete for the same water, but over the season it is the opposite. Barracuda inshore means bait inshore, and the bait is what brings yellowtail in later. Treat barracuda as the advance party.

Can I catch them on my yellowtail tackle?

Yes, as long as you make the lure smaller. Rod and reel can stay the same. Bites are harder to feel, though, so lighter dedicated tackle is more fun.

Lots of bites, no hook-ups.

Your lure is almost certainly too big. Go a size down. If that still does not work, change the hook size or add an assist hook at the rear.

The short version

On Enshunada, barracuda arrive first, in early to mid September.
Barracuda = bait has moved inshore. Yellowtail tend to follow about a month later.
Small and fast: 5-9 cm lures, around 20 g.
They school – if you catch one, repeat the same line.
The teeth wear leaders. Check after every fish.
Soft flesh – chill them immediately.
