The palace of Emperor (the capital city) was transferred from Asuka to Naniwanomiya Palace (present Chuo Ward, Osaka City), which is said to have become the turning point from the politics centered around Gozoku (local ruling families) such as the Soga clan to the politics centered around Emperor.
天皇の宮(首都)を飛鳥から難波宮（現在の大阪市中央区(大阪市)）に移し、蘇我氏など飛鳥の豪族を中心とした政治から天皇中心の政治への転換点となったとされる。
