All this came to an end during one of the darkest chapters of California's history, when Fountaingrove was seized by the government as part of the state's discriminatory Alien Land Laws, which were instituted in 1913, expanded in the 1920s and forbade Asian nationals from owning land or businesses. The childless Nagasawa, who never married, attempted to keep the estate in the family by willing it to his grand-nephew Kosuke Ijichi, born on the estate and thus an American citizen, and his Japanese-born father Tomoki Ijichi. But upon Nagasawa's death in 1934, Kosuke was not of age and the trustee took control of the estate and quickly sold off the land.
