Oshima ("Big Island," pop. 230,000) in Yamaguchi is just offshore of Honshu and 30 miles southwest of Hiroshima City. From Yamaguchi prefecture came the second largest group of Japanese immigrant sugar plantation workers to Hawai'i in the late 19th and early 20th century. Oshima island is a national park and home to the Museum of Japanese Emigration to Hawaii. According to Wikipedia, "Suo-Oshima [the main town, pop.22,070] is a sister city of Kauai, Hawaii. ....Office workers and bus drivers in town wear colorful aloha shirts as a uniform in summer.” Photo by Ka'iulani Murphy.
