Business
Tokyo Gas Co., Ltd. is Japan's largest city gas utility, founded in 1885. With a group structure comprising 231 companies, including 123 subsidiaries and 107 affiliates, the company operates across four segments: City Gas manufacturing and sales, LNG Sales & Trading, Electricity Retail & Wholesale, Engineering Solutions (Energy Solutions), city gas pipeline transportation services (Network), Overseas Resource Development & Energy Supply including the North America Shale Gas Business (Overseas), and Real Estate Development & Leasing (Urban Business). Its main customers are residential, commercial, and industrial gas users in the Tokyo metropolitan area (8,861 thousand retail contracts, 12,693 thousand installed meters) and electricity retail customers (4,337 thousand contracts). FY2026 (ending March 2026) revenue is projected at ¥2,834,749 million.
Business Model
The Network segment provides a stable earnings base through transportation revenue based on regulated tariffs, while the Energy Solutions segment builds up profit through the expansion of Electricity Retail & Wholesale and competitively advantaged raw material procurement. The Overseas segment generates high profitability from the production and sales of the North America Shale Gas Business. The raw material cost adjustment system, which passes through raw material cost fluctuations to tariffs with a lag of up to five months, contributes to medium- to long-term earnings stability.
Company Strengths
Holds 8,861 thousand gas retail customers, 12,693 thousand installed meters (up 129 thousand from the previous fiscal year), and a pipeline network with a total length of 67,287 km. Electricity retail customers have also expanded to 4,337 thousand (up 4.5% year on year), giving the company physical infrastructure and customer touchpoints that competitors cannot easily replicate in a short period.
Centered on Rockcliff Energy II LLC (now TGNR Intermediate Holdings LLC), which became a subsidiary in December 2023, the Overseas segment achieved sales of ¥241,460 million and segment profit of ¥73,837 million (up 222.9% year on year) in FY2026 (ending March 2026). Capital expenditure of ¥139,750 million (up 7.0% year on year) continues to expand production scale.
Secures multinational procurement sources including Alaska, Brunei, Malaysia, Australia, Indonesia, Qatar, Russia, and US shale gas. Under the raw material cost adjustment system, fluctuations in raw material purchase prices can be passed through to rates with a delay of up to five months, resulting in a contract structure that keeps the impact on earnings minimal over the medium to long term.
ENVALITH's Perspective
Performance Trend
Revenue was ¥2,834,749 million (up 7.5% year on year), marking the first increase in two periods. Electricity sales volume expanded substantially to a total of 28,021 million kWh (up 19.5% year on year), and the Overseas segment also contributed to revenue growth due to higher North America Gas prices (a tailwind from market conditions as an external factor). Operating profit recovered to ¥197,677 million (up 48.5% year on year). With the recording of extraordinary income of ¥128,742 million (including gains on sale of fixed assets and reversal of foreign currency translation adjustments, etc.), net income rose 205.8% year on year to ¥226,857 million. For FY2027 (ending March 2027), revenue is projected at ¥2,947,000 million (up 4.0%), while net income is expected to decline significantly by 39.6% to ¥137,000 million due to the drop-off of extraordinary income and other factors. Looking at the trend over the past five periods, operating profit peaked in FY2023 at ¥421,477 million, declined substantially for two consecutive periods thereafter, and partially recovered in FY2026 (ending March 2026).
Growth Strategy
Maximizing profitability through growth in the three businesses of Energy, Solutions, and Overseas, combined with ROIC management
The number of electricity retail customer contracts reached 4,337 thousand at the end of FY2025 (up 4.5% year on year), and total electricity sales volume grew to 28,021 million kWh (up 19.5% year on year), maintaining an expansionary trend. Electricity sales volume is expected to increase further to 28,490 million kWh in FY2027 (ending March 2027). A substantial increase in wholesale sales volume (up 28.4% year on year) contributed to earnings.
Capital expenditure in the Overseas segment reached ¥139,600 million in FY2025 (up 7.0% year on year), the largest scale to date. Combined with rising unit sales prices, segment profit (including equity-method income) achieved a significant year-on-year increase to ¥73,837 million. The company will continue to promote the expansion of upstream assets.
The 26-28 Medium-Term Management Plan, formulated in October 2025, introduced segment-level ROIC management. Profitability of each business is evaluated quantitatively to optimize resource allocation, with priority investment directed toward the three businesses of Energy Solutions, Energy-Related, and Overseas.
Against the backdrop of accelerating social implementation of generative AI and other digital technologies, the Medium-Term Management Plan explicitly states a policy of actively utilizing AI and digital technologies across a wide range of initiatives, from strengthening customer touchpoints to enhancing market competitiveness. This is also expected to contribute to the expansion of the Engineering Solutions business.
Progressive dividends aligned with medium- to long-term growth in earnings per share are positioned as the core of shareholder returns. The annual dividend was ¥110 for FY2026 (ending March 2026) (up from ¥80 in the previous fiscal year), with a forecast of ¥120 for FY2027 (ending March 2027), continuing the trend of dividend increases. Share buybacks (¥200,071 million in FY2026 (ending March 2026)) are also being actively conducted.
