Ibuki iriko dried sardines

Ibuki iriko is made from katakuchi iwashi caught off Ibuki Island and processed on the island into dried anchovies. The name covers several sizes in one family: ooba, chuba, koba, and kaeri.

The island belongs to Kan-onji in Kagawa Prefecture, and the place matters through a simple physical route. The fishing grounds and processing sites are close together, so landed fish can move quickly from the boat toward island workrooms, giving the product a boundary readers can picture in water, docks, and drying work.

The defining work behind Ibuki iriko is the tight span between fishing and processing. Fishing operators handle the chain from catch through processing, keeping the fish connected to the people and equipment that turn katakuchi iwashi into iriko.

Iriko itself is made by boiling katakuchi iwashi in salt water and drying it. Ibuki iriko is also presented as using no food additives; together with the nearby fishing grounds and island processing, that detail helps set the product apart in practical kitchen terms.

The four size names give cooks a concrete way to understand Ibuki iriko. Ooba, chuba, koba, and kaeri all come from katakuchi iwashi, but the sorted sizes let the finished anchovies be recognized by their bodies as well as by their island name.

That size language matters because Ibuki iriko is a family of processed fish rather than a single shape. Kan-onji’s size context places fish smaller than kaeri near the neighboring name chirimen, showing how the words follow the changing size of the fish.

Iriko production on Ibuki Island reaches back to 1862, when Miyoshi Kihachi began making iriko. By 1887, ten operators had been established, giving the island’s production memory dates, people, and working households rather than a vague claim of age.

Later changes were practical: cooperative sales, drying machines, ice facilities, size sorters, automatic kettles, resource-management activity, and electronic bidding entered the production and sales system. Continuity here lives in boats, kettles, drying equipment, sorting work, and shared handling.

The Ibuki Fisheries Cooperative lists multiple producers and trade names in Ibuki-cho, showing that Ibuki iriko is supported by a community of island operators. The cooperative women’s group also wanted the name “Ibuki iriko” to become better known, and promoted it through interviews, visits, and cooperative activity.

Name protection is easiest to understand through its concrete boundaries: katakuchi iwashi from waters off Ibuki Island, processing on the island, cooperative handling, and the producer community in Ibuki-cho. Those boundaries bring the name back to boats, workrooms, and the people who keep it recognizable.

One of the clearest everyday uses for Ibuki iriko is Sanuki udon broth. Iriko rice gives the anchovies another place at the table: cleaned iriko are cooked with ingredients such as fried tofu and konnyaku, allowing the flavor of the fish to enter the rice directly.

The same dried anchovies can become more immediate dishes. Iriko tempura coats the fish in batter and fries it, with aonori-style preparation adding a sea aroma; roasted iriko can also be placed in a cup before warmed sake is poured over it, carrying roasted fragrance and umami into the drink.
