First Japanese diplomatic mission to the United States arrives in California

The first diplomatic mission to the United States left Japan on February 22, 1860 with a seventy-four person staff aboard the USS Powhatan.  They arrived in Hawaii on March 5, 1860 for a two week visit and then sailed for California.  The Powhatan, under Commodore Josiah Tatnall, arrived with the group at the Mare Island Naval Base north of San Francisco a little over a week later.  The embassy then traveled to Washington, D.C. via the Panama route and concluded its visit in late June 1860.
