Business
Our ancestral business was a limestone mining business in Tsukumi City, Oita Prefecture, and entered the marine transportation business to strengthen the stable transportation of our cargoes. With the changing times, we have developed our business with a focus on transportation by ship.
Based on the know-how we have accumulated over the years, we will continue to invest in the safety of people, ships, and cargo, as well as in the next generation toward a decarbonized society.
Company
Building on our 100-year history, we aim to become a company that continues to evolve with the times.
