Nanyo Kohatsu Kabushiki Kaisha Sugar Mill

The abandoned sugar mill complex contains brick structures and a 42.5-meter concrete tunnel connected to multiple chambers throughout the facility.

The Nanyo Kohatsu Kabushiki Kaisha company established this sugar mill during Japan's South Seas Mandate period, operating from 1921 until World War II.

The facility represents the industrial evolution of Rota Island, where 38 percent of farmlands were transformed for sugar cane production in the 1930s.

Visitors can access the remaining structures near the northern peninsula of Songsong village, with the brick tunnel being the most substantial preserved element.

This industrial complex stands as the only remaining brick structure from the Japanese colonial period in the Northern Mariana Islands.
