WWII headquarters for military forces who served in Sitka. During WWII, Japonski Island was connected by a man-made causeway in the 1940s to the surrounding chain of islands which served as a location for bunkers and gunning sites. Though the bunkers and sites are not well preserved, they are accessible by boat. The island was connected to Sitka by the O’Connell Bridge in 1972. Presently, it is the site of a USCG Air Station and Boat Station, University of Alaska Southeast, Mt. Edgecumbe High School, Southeast Alaska Regional Health Center, and the Rocky Gutierrez Airport.
