Japanese companies have completed a $21bn global deal spree for gas supplies since 2023, concentrated on shale resources in the US Gulf Coast. Japan has overtaken the UK, Canada and Australia as the primary source of foreign investment in US gas resources.
Why it matters
Japan is the world's second-largest buyer of liquefied natural gas after China, and its companies are seeking to replace disrupted Middle Eastern supplies and declining reserves in Asia. Market turmoil triggered by conflicts in the Middle East and Ukraine drove the investment push.
Mitsubishi completed a $7.5bn deal this year for US shale gas producer Aethon, and Jera spent $1.5bn last year to acquire the South Mansfield gasfield in Louisiana. Japan's share of foreign US gas investment is two-fifths over the past four years, while the financial impact of these deals has not been disclosed.
The players
Mitsubishi Corporation
Mitsubishi Corporation is a Japanese trading house and conglomerate with large energy holdings that completed a $7.5bn deal for US shale gas producer Aethon.
Jera
Jera is a Japanese power generation company formed as a joint venture of major Japanese utilities, and it acquired the South Mansfield shale gasfield in Louisiana.
The details
Japanese companies have pursued ownership of gas resources rather than relying solely on supply contracts, and Tokyo's foundational energy plan adopted last year encouraged utilities to secure long-term LNG contracts and invest in gas resources and export infrastructure. Japanese LNG buyers also strengthened positions in gasfields in Australia, Indonesia and Papua New Guinea over the past six months.
Timeline
2010-12: Earlier Japanese US shale dealmaking caused widespread impairments across trading houses.
2023: Japanese companies began the current $21bn deal spree.
Last year (2025): Jera acquired the South Mansfield gasfield and Tokyo adopted its foundational energy plan.
This year (2026): Mitsubishi completed the $7.5bn Aethon shale gas deal.
Past six months: Japanese buyers strengthened gasfield positions in Australia, Indonesia and Papua New Guinea.
Market Landscape
Japan's current push into gas ownership repeats the pattern of the 2010-12 wave of Japanese US shale dealmaking, which caused widespread impairments across trading houses. Japan now leads foreign investment in US gas resources, overtaking the UK, Canada and Australia, and that competitive position reshapes the market for LNG supply.
Japanese utilities and trading houses are locking in long-term gas supplies that could affect LNG pricing and availability for consumers in Japan and across Asia. Owning gas resources may help these companies hedge against rising US gas prices and protect LNG trading margins.
The takeaway
Japan's shift from buying gas through supply contracts to owning gas resources signals a long-term strategy to secure energy in an unstable market. The 2010-12 shale losses show that such deals carry real financial risk if prices move against buyers.
