The Yamashiro family photograph collection consists of 9 boxes containing 1,829 photographs. Series I: Albums and Oversize contains photograph albums and oversize prints, some removed from frames for preservation purposes. Boxes 1-2 contain formal portraits of Yamashiro family members. Subjects depicted in the albums include: family snapshots; pets; children; tourism to post-World War II Europe and through the American West; and Yamashiro men's service in the military during and after World War II. Boxes 3-5 contain photograph albums compiled by various members of the Yamashiro family. Box 6 contains oversize prints and panoramas. Several panoramas are stored in a panorama box for preservation. In addition to any identifications made by the album compilers, the donor, Naomi Estolas, included additional identifications on sticky notes throughout the albums. Some of the albums were deconstructed for preservation, but all identifications by family members have been preserved with the corresponding albums.

Series II: Family and Friends consists of three archives boxes containg black-and-white photographs depicting the Yamahsiro family and their friends and associates. Box 7 contains assorted photographs created or collected by the Yamahsiro children. Box 8 primarily consists of photographs taken or collected by Ruby Yamashiro. Box 9 contains formal portraits of largely unidentified people; these are arranged by the location that the photographs were taken.
