Since a domain was formed by a wide variety of number of territories in accordance with climate and natural features, political culture, food culture, etc., a different food culture was born in each region in prefectures which were formed as a result of merging two or more domains such as Yamagata Prefecture, Iwate Prefecture, etc., except for Kagoshima Prefecture which was formed by one domain, Kagoshima Domain (this was because in a period when prefectural transportation facilities did not develop, many borders were set out according to natural landscape such as mountain ranges).
藩は気候風土・政治文化・食文化などの関係によって多種多様の領土面積によって成り立っていた為、藩一つ全体が鹿児島県となった鹿児島藩などは別に、山形県・岩手県など複数の藩が一つにまとまった都府県では地方ごとに食文化が異なる状況が生じている（県交通機関の発達していない時代、国境の多くは山脈等の自然地形によって分かれている為）。
