Ehime Prefecture, Shikoku — Seto Inland Sea fishing and citrus farming traditions; Matsuyama and Uwajima as distinct culinary centres
Ehime Prefecture occupies the western Shikoku coast facing the Seto Inland Sea (Setouchi), and its capital Matsuyama is the gateway to one of Japan's most beautiful food regions — a cuisine defined by the extraordinary seafood of the Inland Sea, the Iyo citrus (especially Ehime's massive mandarin/mikan production) and fruit culture, Kochi's immediate proximity for katsuobushi, and the mountainous interior's wild vegetable and freshwater fish traditions. The Seto Inland Sea produces some of Japan's finest sea bream (tai): the tidal currents between the islands of Ehime's coastline force the fish to develop dense, firm muscle — Imabari-oki tai is considered the benchmark. Ehime's most distinctive dish is tai-meshi (鯛めし, sea bream rice), which exists in two radically different regional versions within the same prefecture: Uwajima-style tai-meshi (raw sea bream sashimi strips mixed with a dashi-soy-sesame sauce, raw egg, and eaten over rice — essentially a warm donburi) vs Matsuyama-style tai-meshi (whole sea bream simmered in a dashi-soy broth with rice in a clay pot, then flaked and mixed through the cooked rice — a one-pot cooked preparation). Both dishes celebrate the same fish in completely opposite preparation philosophies. Ehime's Iyo-kan mandarin, Beni Madonna (紅まどんな, a luxury cross between Iyokan and Margarite Marrow), and Setoka varieties represent the highest tier of Japan's mikan citrus culture.

{"The Uwajima vs Matsuyama tai-meshi distinction is within the same prefecture — both celebrate sea bream but one is raw (Uwajima) and one is cooked (Matsuyama); they are not interchangeable","Seto Inland Sea tai (sea bream) from tidal-current areas has denser, firmer muscle than open-ocean fish — the flesh has a characteristically clean, sweet flavour with no muddy off-note","Ehime mikan (Iyo-kan) skin is thicker than standard mandarin — the pithy layer protects the supremely sweet and low-acid flesh; the citrus must be peeled completely for the correct eating experience","Beni Madonna (December–February) requires careful selection — the skin should be tight and slightly glossy with no soft spots; at peak ripeness the juice is extraordinary","Matsuyama-style tai-meshi: the whole fish must be fresh-killed (ikijime, spike-killed) for the cleanest flavour; the cooking broth becomes the seasoning for the rice"}
{"Dogo Onsen in Matsuyama (Japan's oldest hot spring, documented from ancient times) historically featured specific ryokan cuisine using Inland Sea tai as the centrepiece — combining the Dogo bath with a tai-meshi dinner is the definitive Matsuyama experience","Ehime's Uwajima is worth a separate trip for the tidal-current tai sashimi — the fish is often served in the unique Uwajima donburi style with a raw egg and a house sesame-dashi sauce that cannot be replicated outside the specific fishing community","Setoka mandarin (January–February, very limited supply) from Ehime is sometimes called Japan's finest mandarin — its thin skin, extremely sweet, low-acid flesh, and complex aroma are best at room temperature, not cold"}
{"Confusing the two tai-meshi styles — a visitor who orders Matsuyama-style expecting the raw Uwajima version (or vice versa) will be significantly surprised; each version should be chosen deliberately","Purchasing Ehime mikan that are fully orange at the beginning of the season — early-season Iyo-kan is still slightly green-tinged and underripe; the peak orange-gold colour indicates maturity"}
