We founded Kokuka Sangyo Co., Ltd. in 1947 and have been involved in theshipping industry, starting with the transportation coal, carbon disulﬁde,caustic soda, and other raw materials used in the artiﬁcial silk industry with
our own vessels. Since then, we have expanded our business to include thetransport of organic and specialty chemicals. To achieve these goals, webuilt Japanʼs ﬁrst chemical tanker, molten sulfur carrier, mediumtemperature and medium-pressure liquid ammonia tanker, the worldʼs ﬁrst
molten phthalic anhydride and molten caprolactam carriers, and so forth.
Now, with over 75 years of history behind us, we are engaged in the coastal
and international shipping of mainly methanol and molten sulfur.
We humbly request your continued support as we intensify our eﬀorts as acompany to provide higher-quality services with a focus on safety so that
we can inspire trust beﬁtting our knowledge and experience with over 75years.
