Frank (Sakae) Matsura (1873–1913) was an early 20th-century Japanese photographer who travelled from Japan to America in 1901 where he lived until his early death. More than 1,800 of his frontier-era photographs and glass plate negatives have been preserved by the and Washington State University. For four years he worked at the Elliott Hotel, developing his pictures in the laundry, before relocating to the growing city of Okanogan in 1907. In Okanogan, he built a two-room store on First Avenue which served as a studio and darkroom.
