Introduction
Hakata is a city close to the Genkai Sea. Seafood from northern Kyushu gathers here, and in local izakaya and seafood restaurants, you can casually enjoy fresh sashimi and small dishes to pair with drinks.
Among those seafood ingredients, squid is one of the foods worth trying in Hakata. When Japanese people think of live squid sashimi, many think of Yobuko in Karatsu, Saga Prefecture. Yobuko is a port town facing the Genkai Sea and is famous across Japan for live squid dishes. Hakata is a city where you can enjoy that Yobuko and Genkai Sea squid culture in an urban setting.
The live squid sashimi known today is not simply an old local dish that has remained unchanged for centuries. It also developed as part of postwar ikesu dining culture, where seafood is kept alive in tanks and prepared after the customer orders. Keeping squid alive, cutting it just before serving, and presenting it while it is still extremely fresh — this system makes live squid in northern Kyushu a special experience.
Another essential part of Hakata food culture is mentaiko. Karashi mentaiko is spicy seasoned cod roe. It is based on Korean-style spicy cod roe, but in postwar Hakata it was adapted to suit Japanese tastes. In 1949, Fukuya in Nakasu, Hakata, began selling “Aji no Mentaiko,” which is widely regarded as the starting point of modern Hakata mentaiko culture.
In this article, I will introduce live squid sashimi, mentaiko, ika mentai, and one more mentaiko dish to show how Hakata’s seafood culture and mentaiko culture come together.
What to Try
Live Squid Sashimi
The first dish to try in Hakata is live squid sashimi.
Very fresh squid does not look cloudy white. Instead, the flesh can appear almost transparent. The texture is not simply soft. It has a light, crisp bite, and as you chew, a clean sweetness slowly comes out.
This transparency and texture change over time. Squid is extremely delicate and sensitive to changes in water quality and stress during transport. It can be transported to distant cities, but keeping the same level of transparency you find near the fishing grounds is not easy.
That is why live squid sashimi is especially meaningful in places close to the sea. In Hakata and Yobuko, the Genkai Sea, live seafood tanks, and the practice of preparing squid after ordering all come together to create a freshness that is difficult to reproduce in Tokyo.
At some restaurants, after you finish the sashimi, the legs and fins can be prepared as tempura. First, you enjoy the transparent flesh and crisp texture as sashimi. Then, you enjoy the remaining parts as freshly fried tempura. This sequence is one of the pleasures of squid dining in northern Kyushu.
Mentaiko
Mentaiko is another essential Hakata flavor.
Mentaiko is cod roe seasoned with chili and other flavorings. It has clear saltiness, spiciness, and umami. It is delicious simply placed on white rice, and it also pairs very well with sake or shochu.
Hakata mentaiko is well known as a souvenir, but when you eat it in Fukuoka, you realize that it is more than something to take home. In izakaya, it appears as a small dish with drinks. In restaurants, it is used in pasta, omelets, tempura, dressed dishes, and many other preparations.
In Hakata, mentaiko is both a famous product to buy and a flavor to eat on the spot. Because its spice and umami are so clear, even a small amount can change the character of a dish.
Ika Mentai
Ika mentai is where squid and mentaiko meet.
Thinly sliced squid is mixed with mentaiko, combining the gentle sweetness and chewy texture of squid with the saltiness, spiciness, and tiny popping texture of seasoned cod roe.
If live squid sashimi is a way to taste freshness directly, ika mentai is a way to enjoy squid with a distinctly Hakata-style seasoning. Instead of eating seafood only in its pure form, this dish adds salt, spice, and umami to create another kind of flavor. That is one of the appealing sides of Hakata seafood culture.
Ika mentai connects two local food cultures: the seafood culture of a city near the Genkai Sea, and the everyday mentaiko culture of Hakata. It is simple, but it expresses Hakata very clearly.
One More Dish: Lotus Root Mentaiko Tempura
In Hakata, mentaiko is not only eaten on its own. It is also used as an ingredient in many dishes. Mentaiko can add umami, spice, and saltiness to food in a very direct way.
One example, separate from ika mentai, is lotus root mentaiko tempura.
When mentaiko is stuffed into the holes of lotus root and fried as tempura, the crisp texture of the lotus root meets the saltiness and spice of mentaiko. The light tempura coating, the gentle sweetness of the lotus root, and the umami of mentaiko come together in a dish that works well both as a side dish and as something to enjoy with drinks.
If ika mentai is a combination of squid and mentaiko, lotus root mentaiko tempura is a combination of vegetables and mentaiko. It shows how mentaiko can naturally become part of Hakata cooking.
Tokyo or Trip?
🟠 Local-First — Best in its home region: Hakata, Fukuoka.
You can eat squid sashimi and mentaiko in Tokyo. Mentaiko is sold across Japan, and some restaurants serve mentaiko dishes too.
Still, there is a reason to enjoy them in Hakata.
Because Hakata is close to the Genkai Sea, live squid sashimi can be enjoyed in a fresher state. The transparent flesh, crisp bite, and the experience of having the remaining squid prepared as tempura all help you understand northern Kyushu’s seafood culture.
Also, in Hakata, mentaiko is deeply rooted in the local food scene. It is used naturally in many dishes, not just sold as a souvenir. Ika mentai and lotus root mentaiko tempura are easy examples of how mentaiko appears in everyday dining.
By tasting live squid sashimi, you experience the freshness of the Genkai Sea. By tasting mentaiko dishes, you experience the umami and spice of Hakata. That is why this food is best enjoyed in Fukuoka.

About "Taste of Japan"
Hello, I'm Yuta.
Born in landlocked Yamanashi and having lived in the gourmet city of Sendai for 10 years, I now call Togoshi-Ginza home. My frequent business trips across Japan allow me to constantly explore the diversity of regional flavors.
Why Togoshi-Ginza?
This street is Tokyo’s longest shopping arcade (about 1.3 km), but it holds a special history. It was the very first street in Japan to adopt the "Ginza" name—a tradition that later spread across the country—after receiving bricks from the famous Ginza district following the 1923 Great Kanto Earthquake.
My Wish as a Local
I am not a culinary expert. However, as a Japanese local who knows both the convenience of Tokyo and the origins of regional food, I want to share the "atmosphere" and "personal feelings" that you won't find in standard guidebooks.
The Concept: "Tokyo or Trip?"
Visiting every region of Japan in a single trip is nearly impossible. Some food experiences are worth the travel to the source, while others offer a fully satisfying experience right here in Tokyo.
This blog is a guide to help you make that choice. Based in Togoshi-Ginza, I share my honest experiences and "my personal answer" to help you maximize your culinary journey in Japan.
