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 elds. 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.
