Arai Hakuseki
Fearing extinction of the Imperial Line, Arai Hakuseki proposed that a new branch of the Imperial Family be created. In 1718, retired emperor Reigen bestowed upon his grandson the title of Kan'in-no-miya and land worth 1000 "koku. " This was the first new shinnōke formed since the Arisugawa-no-miya lineage in 1625.
