Daigas Group has businesses in 3 fields
（As of March 31, 2025）
We aim to create value for a sustainable future and evolve as an aggregate of multiple businesses through expansion into new global fields. We will strive to achieve that by leveraging our capital with strengths and our expertise in the three core business segments: the Domestic Energy Business, International Energy Business, and Life & Business Solutions Business (LBS).
Natural gas value chain in the domestic/overseas energy business
Natural gas extracted overseas is transported to Japan as liquefied natural gas (LNG) by dedicated tankers, where it is re-gasified at the receiving terminal and sent to customers through pipelines. This series of flows is the natural gas value chain. Depending on the process, we call it "upstream business" or "midstream and downstream business," and the Daigas Group is building a natural gas value chain overseas just like it is doing in Japan.
- Domestic Energy Business
We are responsible for the operation and maintenance of gas manufacturing plants, as well as the development, operation, maintenance, and management of thermal power plants and renewable energy power plants.
In addition to providing a wide variety of energy sources such as low-carbon LNG and CO2-free electricity, we create environmental value through technological development aimed at realizing a low-carbon and decarbonized society, including engineering projects and plant design.
Osaka Gas Network Co., Ltd.*has established a solid network of city gas supply and a complete security system, and by deepening our expertise and utilizing cutting-edge digital technology, we are delivering city gas safely and securely.
