IHI Corporation Company Profile: Key Facts
The story of IHI begins on Ishikawa Island in Edo (now Tokyo) on December 5, 1853, when Ishikawajima Shipyard was founded as Japan’s first modern shipbuilding facility.
After a 1960 merger between Ishikawajima Heavy Industries and Harima Shipbuilding & Engineering created Ishikawajima-Harima Heavy Industries, the corporation rebranded simply as IHI Corporation in 2007.
The group is headquartered in Toyosu, Koto Ward, Tokyo, and trades on the Tokyo Stock Exchange under ticker 7013.T. As of FY2024, revenue reached 1,626.8 billion yen with consolidated operating profit of 143.5 billion yen.
The total workforce is approximately 27,990 employees across more than 30 countries, organized into four reporting segments. The aero engine, space and defense unit sits at the strategic core, having delivered roughly 86% of the group’s segment operating profit in FY2024 even though it accounted for only 34% of revenue.

IHI Corporation Company Overview: The Foundations of a Propulsion Champion
From Edo Shipyard to Global Tier-One Aerospace Supplier
IHI’s identity has always been tied to engineering Japan’s national infrastructure. The shipbuilding heritage produced disciplines in metallurgy, large-rotor balancing, and high-pressure fluid systems that translated naturally into turbomachinery during the post-war reconstruction.
By the 1960s, IHI had become a license producer for U.S. military jet engines, eventually graduating to indigenous design programs such as the F3 turbofan for the T-4 trainer. That progression produced the technology base that today supports the most ambitious propulsion programs Japan has ever attempted.
The corporate structure separates four business areas: Resources, Energy and Environment; Social Infrastructure; Industrial Systems and General-Purpose Machinery; and Aero Engine, Space and Defense. The latter is described internally as both the profit anchor and the principal growth vehicle for the medium-term plan.
The Aero Engine, Space and Defense Business Area Today
Atsushi Sato, President of the Aero Engine, Space & Defense Business Area, leads three product clusters: aircraft engines, rocket and space systems, and defense equipment.
The cluster touches roughly 70% of Japan’s domestic jet engine output and is the prime contractor for the engines fitted to every Japan Air Self-Defense Force fighter line in service.
The civil aero engine business operates through global partnerships with GE Aerospace, Pratt & Whitney, and Rolls-Royce, while the defense engine business is principally a domestic franchise serving the Japan Ministry of Defense.
The space business runs through subsidiary IHI Aerospace, headquartered in Tomioka, Gunma Prefecture, which is the country’s largest solid-rocket motor producer.
The unit is also Asia’s reference center for civil engine maintenance, repair and overhaul, with shops at Mizuho (Tokyo), Soma (Fukushima) and a new Phase 1 repair facility at the Tsurugashima Aero-Engine Works that began operating during FY2025.
BUSINESS AREA STRUCTURE - AERO ENGINE, SPACE & DEFENSE
------------------------------------------------------
1. Civil Aero Engines - V2500, GEnx, GE9X, PW1100G, Trent, CF34
2. Defense Aero Engines - F3, F7-10, F110, T700 (license), XF9
3. International Programs - GCAP (with Rolls-Royce, Avio Aero)
4. F-35 Regional Depot - F135 component MRO since 2023
5. MRO Footprint - Mizuho, Soma, Tsurugashima
6. IHI Aerospace - H3, Epsilon, satellite propulsion, missiles
7. Defense Systems - SAM rocket motors, UUV, exposed palletsGeographic Reach and Workforce Concentration
The aerospace and defense workforce sits primarily in three Japanese clusters: the Tokyo metropolitan area for engineering and engine assembly, Soma in Fukushima for new repair lines and forging, and Tomioka for solid-rocket motor production.
International extensions include MRO joint ventures and component manufacturing alliances in Asia and North America, including a partnership with Northrop Grumman on global propulsion technology development.
This footprint matters because aero-engine value chains are slow to build. Each new repair line, hot-section fixture, or forging press takes years to qualify, so the investments IHI is making today reset the medium-term capacity envelope through the early 2030s.
IHI Corporation Financial Analysis
FY2024 Results: Records Across the Board
For the fiscal year ended March 31, 2025 (referred to as FY2024 in IHI’s calendar), the group delivered record revenue of 1,626.8 billion yen, an increase of 304.2 billion yen year-on-year. Operating profit reached 143.5 billion yen for an operating margin of 8.8%, up 14.1 percentage points.
The Aero Engine, Space and Defense segment was the standout. Revenue grew 129.3 billion yen to 555.7 billion yen, while operating profit was 122.7 billion yen, dwarfing the contribution from the other three segments.
The civil aero engine spare parts cycle and a stronger U.S. dollar pricing environment were the dominant tailwinds.

H1 FY2025 Results: A Quarter of Record Orders
For the six months ended September 30, 2025, the group’s orders received reached a record-high 893.4 billion yen, up 133.2 billion yen year-on-year. Revenue was 713.6 billion yen, partly impacted by structural divestitures, while operating profit reached 69.4 billion yen.
Inside the aerospace and defense segment, revenue grew 26.2 billion yen to 273.9 billion yen. Operating profit, however, decreased 21.9 billion yen to 54.7 billion yen because the prior period had benefited from low maintenance costs that have since rebounded as V2500, PW1100G, and GE-series engines re-enter heavy shop visits.
Profit attributable to owners of the parent reached a record-high half-year figure of 55.9 billion yen, up 12.0 billion yen, supported by favorable foreign exchange rates and improved tax expenses. EBITDA was 106.2 billion yen.
Revised FY2025 Guidance
In November 2025, management revised the full-year FY2025 forecast upward on profit metrics, while trimming the revenue line. Revenue guidance is now 1,640.0 billion yen, with operating profit of 160.0 billion yen and profit attributable to owners of the parent of 125.0 billion yen.
IHI GROUP FY2025 GUIDANCE (Revised, Nov 2025) - JPY billion
-----------------------------------------------------------
Orders Received .................... 1,850.0 (+60.0 vs prior)
Revenue ............................ 1,640.0 (-10.0 vs prior)
Operating Profit ................... 160.0 (+10.0 vs prior)
Profit Attributable to Owners ...... 125.0 (+5.0 vs prior)
Dividends per share ................ JPY 140 (Interim 70 + Year-end 70)
The order book uplift is heavily driven by the Resources, Energy and Environment segment, especially nuclear energy, while the operating profit raise reflects civil aero engine strength continuing into the back half of the year.
Balance Sheet, Cash Flow and Capital Allocation
Cash flow from operations in H1 FY2025 was negative 57.1 billion yen, principally because of working capital build associated with the order acceleration. The company has been actively divesting non-core assets, including packaging boilers, turf-care machinery, materials-handling systems, concrete construction materials, and transport systems.
Capital allocation has been redirected toward three growth pillars: civil aero engine maintenance and repair capacity, defense aero engines and rocket motors, and small modular nuclear reactor components.
The company’s Group Management Policies framework explicitly prioritizes aggressive investment in those three growth domains while continuing to harvest the conventional businesses.
Long-Term Revenue Architecture
Looking out to the 2030s, the segment’s revenue mix should continue tilting toward aftermarket and high-tech defense work.
The aftermarket on civil engines is expected to climb toward 600 billion yen within that decade, while the defense business has a clear management target of 250 billion yen.
If both targets are achieved, the aero engine, space and defense segment alone could generate revenue exceeding 850 billion yen, representing more than half of where group-wide revenue stands today.
