Nanyo Kohatsu Kabushiki Kaisha complex

The Nan'yō Kōhatsu Kabushiki Kaisha complex was the main support base of the Nan'yō Kōhatsu Kabushiki Kaisha on the island Tinian in the Northern Mariana Islands. The NKKK was an economic development company established by the Empire of Japan to develop the territories of the South Seas Mandate, which it oversaw between the First and Second World Wars. In the Northern Marianas, the company aggressively developed arable areas for sugar cane farming, importing workers from Japan, Okinawa, and Korea. Each of the three major islands had major support facility. On Tinian, this area, now roughly where the island's largest community, San Jose is located on the south coast, consisted of an extensive development, most of which was destroyed during the Battle of Tinian in the Second World War. Of this large complex, only four buildings or structures remain, all of which have been listed on the United States National Register of Historic Places, as rare surviving examples of pre-war Japanese architecture on the islands.
The remains of the NKKK Administration Building are on the west side of San Jose, consisting of an unpainted concrete frame whose wooden elements, including the roof, are long gone. The frame measures 9.8 metres wide, 14.3 metres long, and is about 4.5 metres tall. The main entrance, to the east, is identifiable by a canopy with unique fascia detailing not found on other surviving NKKK buildings in the region. When listed on the National Register in 1981, the structure was being used for storage, and its concrete was deteriorating.
