Management Philosophy

KEYS Bunkering West Japan Ltd. is a coastal shipping company that supplies and sells LNG (liquefied natural gas) as marine fuel on a ship-to-ship basis. We own and operate our fuel supply vessels.
This is the first LNG fuel supply business in western Japan, covering a broad area ranging from Kyushu Island to the Seto Inland Sea region.
We will contribute to the implementation of a carbon-neutral society by meeting a broad range of customer needs while supplying LNG to a wide variety of vessels calling at ports in western Japan.
