In September 1985, a memorial was dedicated to more than 750 internees who left Heart Mountain to serve in the U.S. Armed Forces during World War II and to the memory of 15 Heart Mountaineers who gave their lives for the country: Cpl. Yoshiharuu Aoyama, Sgt. Robert Farmer, Pfc. Ted Fujioka, Pvt. Stanley K. Hayami, S/Sgt. Joe Hayashi, Sgt. John S. Kanazawa, Cpl. Yasuo Kenmotsu, Pvt. Isamu Kunimatsu, Sgt. George M. Mayeda, Pvt. Jim Nagata, Pfc. Toll Seike, Pfc. William Taketa, Lt. Kei Takahashi, Pfc. Fred Yamamoto, and Lt. Hitoshi Yonemura. It called for the injustices of the removal and incarceration of 120,000 persons of Japanese ancestry during World War II, two-thirds of whom were American citizens, never to be repeated. It was presented by the Heart Mountain High School Class of 1947 on behalf of the 10,700 persons interned from 1942 to 1945, with appreciation to the people of Park County who made it possible.
