Fukuoka Prefecture is the place for enjoying the best mentaiko! Featuring lunch spots, hands-on experiences, and gifts

Karashi mentaiko (spicy Alaska pollock roe) is a signature Fukuoka specialty. Fukuoka Prefecture is the “land of karashi mentaiko,” where over 200 producers can be found. This article covers information on nationally renowned shops to restaurants serving karashi mentaiko, factory tours and hands-on experiences, and recommended gifts.

What is karashi mentaiko?

Karashi mentaiko is made from the ovaries of the Alaska pollock, marinated in a seasoning liquid containing chili peppers. The culinary tradition of processing and eating Alaska pollock roe is said to have originated on the Korean Peninsula, with the name “mentaiko” derived from the Korean word “myeongtae,” meaning pollock.

While karashi mentaiko is now enjoyed throughout Japan, Fukuoka Prefecture is ranked as the undisputed national leader for both production and consumption volumes! It pairs perfectly with any ingredient and has endless possibilities for adaptation into a wide range of dishes, from rice and pasta to bread and egg dishes.

How did karashi mentaiko gain widespread popularity in Fukuoka?

How did karashi mentaiko, originating from the Korean Peninsula, become a specialty of Fukuoka?

This is deeply connected to the achievements of Toshio Kawahara, founder of Fukuya. Kawahara could not forget the “mentai” (cod roe pickled in kimchi) he had eaten in Korea, where he spent his childhood after the war. He developed his own version to suit Japanese tastes, and in 1949, sold Japan's first karashi mentaiko in Nakasu, Hakata. Kawahara chose not to patent his production formula and generously shared information on his manufacturing method with others in the industry. This led to the emergence of numerous karashi mentaiko shops mainly within Fukuoka City, propelling its growth into a signature delicacy representative of Hakata. In 1975, the opening of the Sanyo Shinkansen line to Hakata served as a catalyst that helped karashi mentaiko gain recognition across Japan.

Key points for choosing karashi mentaiko

The flavor and spiciness of karashi mentaiko vary greatly by manufacturer. Here are some key points to help you choose.

(1) Spiciness
There is a wide range of options, from mild to extra spicy. Some shops even allow you to choose the level of spiciness.

(2) Shape
Choose the shape to suit the purpose of use: “ipponmono” are whole pieces with perfect shapes, making them ideal for gifts; “kireko” or “barako” are pieces that became crumbled during the manufacturing process, making them more affordable and suitable for home use or cooking. Convenient tube types are also available.

(3) Characteristics of products from different manufacturers
Each manufacturer has its own unique focus and production methods, resulting in distinct flavors and rich individuality! If tasting samples are available, we recommend trying the flavor before purchasing.

Roe that is most suitable for making karashi mentaiko is aged slowly for 168 hours. Yamaya's products are defined by the subtle notes of fragrant yuzu that emerge through the sharp spiciness.
