Koga Sengyo Seafood Restaurant Around Hakata – Fresh from Market to Bowl

Koga Sengyo (古賀鮮魚)

As I mentioned in a previous post, my husband and I visited Hakata in Fukuoka last year. One of the things I was most excited about was enjoying the local cuisine. In Top 3 Seafood Restaurants to Visit Around Hakata, I shared how Hakata is famous for its fresh seafood—thanks to its close proximity to the Genkai Sea’s rich fishing grounds and vibrant markets like Nagahama Fish Market (長浜鮮魚市場) and Yanagibashi Rengo Fish Market (柳橋連合市場), which guarantee a steady supply of fresh catch each day.

The area is filled with exceptional seafood restaurants. This time, we made our way to Yanagibashi Rengo Fish Market (柳橋連合市場), just a 20-minutes walk from JR Hakata Station.

In Yanagibashi Fish Market, there are many seafood restaurants to choose from, and we decided to try Koga Sengyo (古賀鮮魚), which is both a fishmonger and a restaurant—meaning the seafood they serve is incredibly fresh, often sourced straight from their own stall.

Koga Sengyo (古賀鮮魚)

Koga Sengyo (古賀鮮魚) is one of the most popular spots in Yanagibashi Rengo Fish Market (柳橋連合市場), but when we visited on a Thursday at 2 p.m., it wasn’t crowded at all. The quiet midafternoon setting made it feel like a hidden treasure tucked within the bustle of the market.

The walls of Koga Sengyo were lined with a wide array of handwritten menus, giving the restaurant a lively, local charm. According to the staff, their most popular dishes include Kaisen Don (海鮮丼), Tuna Don (マグロ丼), Assorted Deep-Fried Seafood (海鮮ミックスフライ), Deep-Fried Horse Mackerel (アジフライ), and Assorted Sashimi (刺身盛り合わせ).

Kaisen don (海鮮丼)

Kaisen don (海鮮丼)

My husband ordered the Kaisen Don (海鮮丼), which cost just 1,100 yen and came with wakame seaweed soup and a few side dishes. It’s no wonder Kaisen Don is their most popular dish—it truly delivers on quality, flavor, and value. It had the vibrant slices of tuna, salmon, squid, and shrimp are beautifully arranged on rice, creating a feast for both the eyes and the palate. The sashimi was incredibly fresh and of impressive quality—we couldn’t believe it was only about $7.50! For this kind of seafood bowl in the U.S., we’d easily expect to pay over $50. If you visit Koga Sengyo, the Kaisen Don is an absolute must-try.

I ordered the Makanai Don (まかない丼) for just 900 yen, which also came with wakame seaweed soup and a few side dishes. The bowl was topped with a generous variety of fresh fish, including tuna, salmon, sea bream, and ikura (いくら), or salmon roe. I had seen this dish recommended by several Japanese YouTubers, and now I understand why—it felt like a hidden gem. At only 900 yen (about $6.20), it was an absolute steal for the quality and variety it offered.

Deep-Fried Horse Mackerel (アジフライ) Half Size

We also ordered a half-size portion of deep-fried horse mackerel (ちょっとアジフライ) for just 350 yen. I had originally planned to visit Shokudo Hamakani (食堂はまかに), a restaurant known for its seafood dishes—especially horse mackerel (鯵, アジ)—but it happened to be closed that day. Thankfully, we still got to enjoy this dish at Koga Sengyo, and it turned out to be a delightful surprise. The horse mackerel was soft, fluffy, and perfectly fried.

Koga Sengyo left a lasting impression—not just for its friendly atmosphere and unbeatable prices, but for one unforgettable Kaisen Don that captured the true flavor of Hakata.
