Hello, fellow travelers!
Even when I’m completely full, I still find myself peeking into the fridge.
This is Binako, a writer for SaruKuma!

Today, I’m excited to introduce you to a hidden gem located in
Yamaga, Yamaga City, Kumamoto Prefecture:
“Okazaki Fresh Fish Shop” (Okazaki Sengyoten).

Yes, it’s a fresh fish shop — but I’d heard rumors that they serve an amazing mackerel burger here, so I headed over with high expectations!

I mean, just the name “mackerel burger” already sounds delicious, right?

Inside the shop, you’ll find an impressive selection of fresh seafood — exactly what you’d expect from a proper Japanese fish market!

The slipper lobsters (uchiwa-ebi) caught my eye personally…

And here we have fresh sashimi!
What’s more, the prices are surprisingly affordable!

Since sashimi is raw, I had to pass this time as a tourist, but everything looked incredibly fresh and tempting.

They also stock kombu (dried kelp), perfect for making traditional Japanese dashi broth — or even eating as is!

There’s also a wide variety of dried fish (himono) — a Japanese culinary staple!

There are even live shrimp swimming around — kids are going to love this! lol
Watching them is surprisingly relaxing. Haha.

If you’re driving, you can park right beside the shop!

Recommended Menu

Here’s the star of the show!

Mackerel Burger — 380 yen
Other mouthwatering options include:
Mackerel Burger with Charred Miso — 430 yen
Mackerel Burger with Mentaiko Mayo (spicy cod roe mayo) — 430 yen

And a limited-time special:
Mackerel Curry Burger — 430 yen

So many tempting choices — it’s hard to decide!

This time, I went with the classic Mackerel Burger — 390 yen!

It looks delicious. The mackerel fillet is huge.

They cook it fresh after you order, so expect about a 10-minute wait —
but it’s worth every second because the buns come out wonderfully fluffy!

And the mackerel? Hot off the grill and steaming!
I was already in heaven before even taking a bite!

OH MY GOODNESS, THIS IS AMAZING!

Freshly grilled is simply the best.
The buns are pillowy soft, the mackerel is juicy with that signature rich, fatty flavor,
and the crisp vegetables add the perfect crunch — there’s no way this could taste anything but heavenly.

I’m completely hooked.

The slice of lemon tucked inside adds a bright, refreshing accent that balances out the richness beautifully.

You’ll devour this in no time.

For this level of deliciousness, 390 yen is an absolute steal.
I’m already planning my next visit to try a different flavor!

If you’re traveling through Yamaga, you absolutely have to try this — you won’t regret it!
