Since the 1950s, we have had advanced into the transportation of bond bunkers (bonded fuel oil) for ocean-going vessels. Currently, the business holds the top share in the domestic transportation market and plays a key role in the safe navigation of vessels in Japan and overseas. Bonded bunker delivery, which is subject to various restrictions depending on the vessel type, loading/discharging status, port and landing bridge management, is a complex and dangerous task. Developing our own reliable safety management system and holding one of the largest fleets in Japan, we always strive to deliver safely bond bunkers our customers entrust us with.

We operate electric powered tankers with large-capacity lithium-ion batteries. We have achieved zero emissions of greenhouse gases (GHGs) such as CO2 (Carbon Dioxide), NOx (Nitrogen Oxide), SOx (Sulfur Oxide), and soot from our vessels by switching her power sources from conventional fossil fuel oil to rechargeable batteries and using electricity derived from renewable energy power generation. The first vessel “ASAHI” has been engaged as a bunker tanker in Tokyo Bay since April 2022, and second vessel “AKARI” since April 2023. In this project, we are working to apply an advanced and innovative manner to solving issues of both global and working environment maritime shipping faces as a social infrastructure.
