Pioneer of petrochemical product transportation

Ever since we began the transportation of petrochemical products in 1958, we have been transporting petrochemical products directly linked to everyone’s life as a pioneer of petrochemical product transportation.

Specifications to reduce the workload of mariners and more thorough quality control

Our vessels are equipped with a deep well pump for a cargo pump to reduce the workload of crew members by eliminating pumping chambers. We recently constructed a vessel with a cargo tank material of SUS316 and equipped it with a nitrogen generator as the standard to further improve quality control in PPM units, something that is indispensable in the transportation of chemicals. The nitrogen generator can control the combination of combustible gas and air, which requires careful attention in the transportation of hazardous materials, allowing us to transport products more safely.

Also support small lots

In addition, the first domestic chemical tanker with one-tank, one-line, and one-cargo pump enables the transportation of four different types of products and completely independent loading and unloading, as well as small-lot transportation.

Service expansion to Far Eastern regions as an extension of coastal transportation

In recent years, we have expanded our services to Far Eastern regions as an extension of coastal transportation using vessels for domestic and international shipping to respond to our clients’ further needs, in collaboration with the Company’s Chemical Group.

Provision of safe, stable, and secure transportation to become everyone’s transportation partner

We will continue to develop and promote our transport fleet by applying the experience cultivated and built up together with the shipowners, aiming to be your partner company with the top position in Japan in terms of both the number of fleets owned and the volume of transport. As your partner we will provide safety, security and stability, with an efficient transportation service.
