"Masao was an all-star on any team in any league. Masao and his brother Noboru were baseball legends in the Guadalupe region. While Masao was batting .400 for his Tule Lake California team in a Detention Camp, his brother was killed in action flying over Tokyo for the Sho-en Koku-Hei"

In April 1942, at the age of 20, Mas' family was evacuated to the Tulare Assembly Center, which was built on the Tulare County Fairgrounds. Many of his baseball teammates' families had been evacuated to the same assembly center, where they organized their own softball league.
In October of 1942, Mas' family was moved to the Gila River War Relocation Center. The baseball players at Gila River were organized into ten teams, most were organized around their pre-War lineups. Baseball games were a huge form of entertainment at Gila River. Although teams occasionally practiced during the week, official games were only played on weekends.
Mas was later transferred to the Tule Lake Detention Center for the remainder of the war.
