Japanese Food Culture Regions — A Geographic Overview (日本の食文化地域)

Japan — Japan's regional food culture developed through the Edo period's restricted inter-domain travel (the sankin-kōtai system required daimyo to travel between their domains and Edo, carrying food culture along established routes) and through the development of specific agricultural and fishing traditions in each climate zone. The Kantō-Kansai divide intensified through the Edo period as the two cultural centres (Tokyo=Edo and Osaka-Kyoto) developed increasingly distinct culinary identities.

Japan's food culture is profoundly regional — more so than most countries of comparable geographic size — with distinct culinary identities in each of the nine major regions: Hokkaido (乳製品、山菜、海鮮、ジンギスカン — dairy, mountain vegetables, seafood, jingisukan); Tohoku (きりたんぽ、わんこそば、牛タン — kiritanpo, wanko soba, beef tongue); Kantō/Tokyo (江戸前寿司、もんじゃ焼き、もつ鍋 — Edomae sushi, monjayaki, motsunabe); Chubu/Nagoya (味噌煮込みうどん、手羽先、きしめん — miso nikomi udon, chicken wings, kishimen flat noodles); Kansai/Osaka-Kyoto (たこ焼き、お好み焼き、懐石 — takoyaki, okonomiyaki, kaiseki); Chugoku/Hiroshima (お好み焼き広島風、牡蠣 — Hiroshima okonomiyaki, oysters); Shikoku (うどん、カツオ、すだち — udon, bonito, sudachi); Kyushu (ラーメン、とんこつ、からし蓮根 — ramen, tonkotsu, karashi-renkon); Okinawa (ゴーヤチャンプルー、ラフテー、泡盛 — goya chanpuru, rafute, awamori).

The flavour difference between Kantō and Kansai — the most fundamental Japanese culinary divide — is immediately perceptible: Kantō noodle broth (both soba and udon) is darker, stronger, more directly savoury from heavier soy seasoning; Kansai broth is pale amber, dashi-forward, subtler, more complex in its understatement. Kantō tamagoyaki is sweet; Kansai dashimaki tamago is savoury. Kantō miso tends dark and robust; Kyoto miso is white and sweet. The East-West divide creates a culinary landscape where the 'same dish' in the two regions may be essentially different preparations.
