Group Company Management StructureGroup Management Structure
The Tokyo Gas Group currently consists of Tokyo Gas Co., Ltd.,
together with 55 subsidiaries and four equity-method affiliatedcompanies. With the deregulation of the energy sector, TokyoGas now faces escalating competition from both inside andoutside the industry. In April 2004, we introduced a new groupstructure known as the “Strategic Business Unit” (SBU) system, which is designed to focus all of the resources of the Tokyo Gas Group toward the task of surviving and succeeding in

the increasingly competitive environment. Under this structure,Tokyo Gas corporate divisions are linked with group companies
to form business units in each business area. The divisions andcompanies work closely together on tasks ranging from theformulation of business strategies to the allocation of management resources and the management of operations, all under
the responsibility of unit managers. The aim of this cooperative approach is to maximize our group potential and further
strengthen our competitiveness.
