Nanyo Kohatsu Kabushiki Kaisha Sugar Mill

The Nan'yō Kōhatsu Kabushiki Kaisha Sugar Mill is a former industrial facility in the village of Songsong on the island of Rota in the Northern Mariana Islands. Its ruins are a significant reminder of the South Seas Mandate period, when Imperial Japan engaged in large-scale sugar cane farming in the Northern Marianas, and are the only brick structure in the Northern Marianas. The sugar mill on Rota was one of the major installations of the Nan'yō Kōhatsu Kabushiki Kaisha, the Japanese company responsible for economic development of the mandate area. The remnants of this sugar mill, all that survived the Allied capture of Rota during World War II, are located on the north side of the peninsula that projects southwest from Songsong, and consist of fragments of brick and concrete structures. The most impressive single element is a brick and concrete tunnel 42.5 metres (139 ft) long, from which openings lead to the locations of other parts of the once-extensive complex.[2]
