ichimon 一門
One of five groups of related stables.
An ichimon is a group of related stables. Since 2018 there have been five, and every stable must belong to one: Dewanoumi, Nishonoseki, Takasago, Tokitsukaze and Isegahama. They act as voting blocs in the association's board elections. When a stable closes, its wrestlers usually move to another stable, often in the same group.
