Consists primarily of correspondence to Kiyoshi Paul Shimada (1916-2003), a Japanese American farmer from Lodi, California, who was imprisoned along with his family during World War II. The collection includes handwritten letters, postcards, and invitations from various friends and family; photographs with negatives; and an envelope with receipts for a store located in Arkansas. The photographs and negatives appear to be from the latter part of the 20th century, after Shimada's incarceration at Rohwer.

The correspondence are addressed to Rohwer, where Shimada was imprisoned from September 1942 through July 1943 before joining the U.S. Army like his two brothers, Isamu Shimada and Tsuyoshi Shimada. Some of the correspondents in the collection were Japanese American friends at other concentration camps: Mabel Miyagishima, who was incarcerated at the Stockton Assembly Center; George Miyama, at the Granada Relocation Center; Fred Ouye, at the Tule Lake Relocation Center; and a letter in Japanese from someone who was incarcerated at the Gila Relocation Center. Paul Shimada also received letters from his brothers after they had joined the U.S. Army. The other letters are from people back home in Lodi, California.
