The Southern Pacific Railroad built the boarding house in 1909. It was purchased in 1920 by the Kuramoto family. They ran in until they were interned in 1942 during WWII. They never returned to run the boarding house.
It is not known for fact what went on after the Kuramoto family was taken away. The rumors of gambling, prostitution, and more run rampant. Dave and Ann have felt watched by an Asian woman in black almost every time they visit.
