History of the Japanese in Portland, Oregon

The history of ethnic Japanese in the Portland, Oregon area dates back to the 19th century.
History.
The first historical record of Japanese in the Portland area is that of the three castaways Iwakichi, Kyukichi, and Otokichi, who lived for several months at Fort Vancouver in 1834. They were the sole survivors of a Japanese rice transport ship that had been caught in a typhoon, damaged, and blown far off course. After more than a year at sea, their rudderless ship finally beached on the northwest corner of the Olympic Peninsula, where they were briefly enslaved by the indigenous Makah people. Upon hearing of the three Asian captives, John McLoughlin, the Chief Factor (agent) for the Columbia District at the Hudson's Bay Company, secured their release and had them delivered to Fort Vancouver. They stayed there, along the banks of the Columbia River, for several months before eventually heading to London and then back to Asia.
The first person of Japanese descent to settle in the Portland area is said to have been Miyo Iwakoshi, who moved to Gresham with her Scottish husband and daughter in 1880.
Portland once had two Japantowns: one located in Northwest Portland's Old Town Chinatown area and the other in Southwest Portland. Before World War II, the Japantown in the Northwest District was home to more than 100 businesses, and was Oregon's largest Japantown. 
In February 1942, shortly after the Japanese attack on Pearl Harbor, President Franklin D. Roosevelt issued and signed Executive Order 9066, clearing the way for the mass incarceration of all persons of Japanese ancestry on the American West Coast in inland concentration camps. More than 3600 ethnic Japanese from the Portland region were first ordered to a hastily constructed internment facility, the Portland Assembly Center, on the grounds of the Pacific International Livestock Exposition in Portland's Kenton neighborhood. From there, most were sent in groups by rail to the Minidoka Relocation Center in Idaho, following the completion of that camp's construction. Smaller numbers were sent from the assembly center to the Heart Mountain Relocation Center in Wyoming and the Tule Lake Relocation Center in California. Those internees who returned to Portland following the closure of the camps found that Portland's once bustling Japantowns were gone.
