Mentaiko: Fukuoka's Spicy Cod Roe Specialty

Mentaiko is salted pollock roe cured in a chili-based marinade, and while it's sold nationwide today, it's a genuine Fukuoka specialty. It developed after World War II, influenced by Korean-style fermented pollock roe (myeongnan jeot) brought via the region's historic ties to the Korean peninsula, and was adapted into the milder, chili-forward version now associated with the city.

Mentaiko is most commonly eaten over hot rice, stuffed into onigiri, or grilled lightly to firm the texture, and it's also used as a pasta sauce — mentaiko pasta is now popular across Japan, not just Fukuoka. Spice levels vary by producer, and the roe is soft enough to eat straight from the sac. It's one of the most common Fukuoka omiyage gifts, sold in gift-boxed sets at train stations and airports.
