Japanese Shikoku Cuisine: Kochi's Katsuo Culture and Tokushima Ramen
Japan — Shikoku Island (Kochi, Tokushima, Ehime, Kagawa Prefectures)
Shikoku, the smallest of Japan's four main islands, houses four distinct prefectural food cultures united by mountainous terrain, warm Pacific coastal access (Kochi), and the Seto Inland Sea (Kagawa, Ehime). Kochi Prefecture is the cultural homeland of katsuo (bonito) consumption — not as dried katsuobushi but as katsuo tataki (quickly seared whole loin, chilled, served with citrus ponzu, raw garlic, and ginger). Kochi's residents consume more fresh bonito per capita than anywhere in Japan, and the local variant of tataki involves charcoal-searing a whole side of bonito while holding it on a skewer, producing a thick, dramatically seared exterior around a raw, cool interior. Tokushima Prefecture is known for Tokushima ramen, a rare style featuring a pork-bone (tonkotsu) and soy base, topped with simmered pork belly slices and a raw egg that is stirred into the hot broth — the egg cooks partially in the bowl. Ehime Prefecture (the Uwajima area) produces ja-ja-men (sour horse mackerel), and tai-meshi (sea bream rice) in two competing styles: the Matsuyama version (cooked sea bream fillet on rice) versus the Uwajima version (raw sea bream sashimi served over raw egg and rice). Kagawa Prefecture is the udon homeland (Sanuki udon — covered separately).
