Biography
Sumio Tsuyuki was a Japanese American participant in the Heart Mountain draft-resistance movement. After being confined at Heart Mountain during World War II, he was prosecuted for refusing military conscription and imprisoned at McNeil Island in Washington. His mother and father had died, and he said he needed to care for his younger sisters.
Forced-removal chronology
The institutional biography records confinement at Pomona Assembly Center on May 10, 1942, followed by arrival at Heart Mountain on August 23, 1942. These are confinement-stage milestones, not a complete continuous-custody span or a change to the draft-resistance case. Heart Mountain institutional biography.
The Heart Mountain institutional biography records that Sumio Tsuyuki was pardoned by President Harry Truman on December 24, 1947. This pardon is distinct from the earlier physical release from prison. Heart Mountain institutional biography.
