The other three firms are Kajima Corp., Sapporo Engineering Ltd. and Toray Industries Inc.

Japan's target under the Kyoto Protocol accomplishment plan is to shift 500,000 kl (crude oil equivalent) of its annual transportation fuel use to biofuel by fiscal 2010, and the oil industry has started introducing Bio Ethyl Tertial-Butyl Ether (Bio ETBE; synthesized from bioethanol and petroleum gas) on the market in an effort to meet this target. They started pilot sales of the product in 2007 and plan to begin full-scale introduction of 840,000 kl by 2010. 840,000 kl of Bio-ETBE is equivalent to approximately 360,000 kl of bioethanol.
