Yobuko Squid
Yobuko squid is a specialty of Karatsu, known for its translucent flesh, natural sweetness, and pleasantly firm texture. In the port town of Yobuko, different types of squid are landed throughout the year. Kensaki squid can be enjoyed from spring to autumn, bigfin reef squid from autumn to spring, and spear squid or cuttlefish from winter to spring. The local specialty is live squid sashimi. Some restaurants prepare squid quickly after taking it from an in-house tank, allowing diners to enjoy its freshness both visually and in taste. After the sashimi is served, the remaining tentacles are often prepared as tempura or grilled with salt, so the flavor of the squid can be enjoyed to the end. Many visitors also come to the Yobuko Morning Market looking for fresh squid.

Karatsu Q-saba (Brand Mackerel)
Karatsu Q Saba is a fully farm-raised chub mackerel developed through joint research by Karatsu City in Saga Prefecture and Kyushu University. It is produced using a complete aquaculture cycle, from artificial hatching to raising the fish to maturity, collecting eggs, and hatching them again.

It is known for its firm texture and refined umami. As of May 2026, shipments have been suspended, and the timing of their resumption has not yet been determined.

Karatsu ware is pottery known for its rustic beauty that brings out the character of the clay, as well as its functional elegance that enhances the food served on it. The clay, iron-rich glazes, and effects created during firing give each piece a distinctive appearance, while the simple, understated forms develop a deeper charm the more they are used in daily life. With a wide range of everyday vessels such as rice bowls, plates, mukozuke small dishes, and sake ware, Karatsu ware naturally complements not only Japanese cuisine but also Western-style dishes. As tableware that receives seasonal ingredients at the dining table, it conveys the climate of Karatsu and the warmth of handcraftsmanship.
