INSTITUTION PROFILE / SPACE INDUSTRY
JAXA (Japan Aerospace Exploration Agency)
Japan's implementing agency: it supports national space development with technology and hands out money through the Space Strategy Fund
JAXA is a national research and development agency that supports Japan's space development and use with technology. It develops and operates the H3 rocket, satellites and space probes, and since 2024 it has distributed money to companies and universities for technology development through the Space Strategy Fund. But space policy is set by the government, launch and satellite-control permits come from the Prime Minister, and radio licenses from the Minister of Internal Affairs and Communications. JAXA is not a government ministry. This profile looks at one question: what JAXA can decide for the space industry, and what it cannot.

1. JAXA in 30 seconds
JAXA is not the body that decides policy; it is the body that carries it out with technology. It is positioned as the "core implementing agency" that supports the whole government's space development and use with technology Sourced, and the competent minister sets its medium- to long-term goals based on the Basic Plan on Space Policy Sourced. Permits for launches and satellite control come from the Prime Minister, and radio station licenses from the Minister of Internal Affairs and Communications Sourced. Still, JAXA matters to industry because, beyond its core work on the H3 rocket and more, it now allocates money to companies and universities through the Space Strategy Fund (JPY 300 billion in grants to the fund counted in its FY2024 funding).
2. What kind of body it is: the four types of influence
The institutions in space-industry articles are not companies, and they do not trade for profit. They differ in the route by which they influence the industry, which gives four types. JAXA belongs to the first type on the left, "Funding".
3. What it does for the space industry
JAXA's work with the industry falls into three kinds: building and operating things itself, allocating funds, and contracting with companies. Amounts are in yen, and years are Japanese fiscal years (FY2026 runs from April 2026 to March 2027).
| Area | Scale and status | What it involves | Main players |
|---|---|---|---|
| Rockets (H3) | H3 flight 8 failed on 22 December 2025. H3 flight 9 launched the Michibiki 7 satellite on 11 August 2026 | H3 is Japan's main large rocket, developed as the successor to H-IIA. JAXA and Mitsubishi Heavy Industries jointly received a Nikkei award for it. A ministry-level meeting accepted the cause analysis for flight 8 in July 2026 Sourced | JAXA, Mitsubishi Heavy Industries |
| Satellites (Earth observation and more) | In FY2024, the ALOS-4 satellite was launched on H3 flight 3 | EarthCARE (Japanese name "Hakuryu") was developed jointly by Japan and the European Space Agency (ESA) and launched on a SpaceX Falcon 9 in May 2024 | JAXA, ESA, manufacturers |
| International exploration | In April 2024, Japan and the U.S. signed an implementing arrangement for lunar exploration with a pressurized rover | Japan provides a crewed pressurized rover, and two lunar landings by Japanese astronauts are provided for. JAXA took part by coordinating technical and legal aspects | JAXA, NASA, the education and science ministry |
| Space Strategy Fund | Phase 1 (from FY2024): JPY 300 billion, 22 themes Phase 2 (from FY2025): JPY 300 billion, 24 themes Phase 3 (from FY2026): JPY 200 billion, 19 themes | It supports technology development by companies, universities and research bodies for up to 10 years, with the aim of securing JPY 1 trillion in total. JAXA acts as the funding agency, running calls, screening and contracts. The money is grants and commissioned work, not equity | JAXA, companies, universities |
| Commercial debris removal demonstration (CRD2) | Phase II contract signed in August 2024 | JAXA selected Astroscale as its contract partner and signed a partnership-type contract | JAXA, Astroscale |
The fund's basic policy targets themes where "companies and universities, not JAXA, take the lead", and says that proposals involving a launch should in principle launch from Japan Sourced. For a parts or materials maker, the fund's technology themes (rocket parts, satellite parts and so on) can be an entry point for applying to a call. Whether a company can apply depends on each theme's requirements, so details must be checked in each call. Because of the domestic-launch principle, equipment built with fund money probably has to rely on launch providers in Japan (Inference).
4. How far its influence reaches (what it can and cannot decide)
| Aspect | What JAXA has | What JAXA does not have |
|---|---|---|
| Powers | The work set out in the JAXA Act: R&D, launch and operations, and grants to private bodies and others. Running the Space Strategy Fund's calls, screening and contracts | Deciding space policy. Permits for launching and satellite control (the Prime Minister). Radio station licenses (the Minister of Internal Affairs and Communications). The fund's basic policy (designed by the Cabinet Office and ministries) |
| Geography | Projects funded by Japan's budget. The fund's awardees are mainly Japanese companies and universities. Joint projects with NASA and ESA in international cooperation | Power over other countries' policy, or to regulate foreign companies |
| Time span | The fund supports work for up to 10 years. Multi-year projects under a medium-term plan | The state sets the budget each fiscal year. The competent minister sets the medium- to long-term goals |
| Scale | 2,505 full-time staff. An FY2026 initial budget of JPY 154.8 billion. Fund phases 1 to 3 total JPY 800 billion Our calculation | The fund's JPY 1 trillion total is an aim; securing all of it has not been decided |
JAXA's budget figures must be read separately for the initial budget, supplementary budgets and the fund. On JAXA's website, the budget series (which excludes the Space Strategy Fund) shows FY2025 at an initial budget of JPY 154.5 billion plus a supplementary budget of JPY 60 billion, for JPY 214.5 billion, and FY2026 at an initial budget of JPY 154.8 billion (as of 7 April 2026, no supplementary budget) Sourced. The Space Strategy Fund is separate. It was created in March 2024 through a supplementary budget and an amendment of the JAXA Act. JAXA's FY2024 funding included grants of JPY 300 billion to the fund (the year's funding was JPY 133.353 billion in operating grants, JPY 55.509 billion in facility grants and four other subsidies, JPY 300 billion in grants to the fund, JPY 63.356 billion in commissioned income and more) Sourced. The JPY 800 billion for fund phases 1 to 3 is the sum of each phase's size, and the fund's JPY 1 trillion total is an aim, not a secured amount Not yet confirmed.
5. Companies and organisations it works with
| Programme | Companies and organisations named in JAXA's materials | The relationship | Profile in this series |
|---|---|---|---|
| H3 rocket | Mitsubishi Heavy Industries | JAXA and Mitsubishi Heavy Industries jointly received a Nikkei award for the H3. JAXA's page links to Mitsubishi Heavy Industries' launch service site Sourced | Mitsubishi Heavy Industries |
| Commercial debris removal demonstration | Astroscale | Chosen as the Phase II contract partner in August 2024, under a partnership-type contract Sourced | Astroscale |
| Launch of an Earth observation satellite | SpaceX, ESA | The jointly developed EarthCARE was launched on a SpaceX Falcon 9 in May 2024 Sourced | SpaceX |
| Lunar exploration | NASA | In April 2024 the Japanese minister and the NASA Administrator agreed on a Japanese pressurized rover and two lunar landings by Japanese astronauts Sourced | - (see our separate profile of NASA) |
6. Outlook
| What the sources suggest | Primary source | Category |
|---|---|---|
| The launch of the Martian Moons eXploration probe (MMX) on H3 flight 10 is scheduled for 04:41:03 on 20 October 2026 (Japan time), with a reserve period to 7 November. Our check date is 17 October, before the launch | JAXA press release (20 August 2026) | Not yet confirmed |
| The Space Strategy Fund has reached phase 3 (FY2026) and aims to secure JPY 1 trillion over up to 10 years. On 16 October 2026 it posted the award results for the "LEO hub reboost technology" theme | The fund's official page and overview (July 2026) | Not yet confirmed |
| A bill amending the Space Activities Act (adding launches of a rocket alone to the permit system) was sent from the House of Councillors and passed the House of Representatives' Cabinet Committee on 10 June 2026. We could not confirm its enactment or start date. Suborbital flights and reentry are not part of this amendment | Cabinet Office final summary (9 December 2025); House of Representatives committee record (10 June 2026) | Not yet confirmed |
| If the amendment is enacted, the permit framework for private rockets would widen, which could affect the outlet (launch from Japan) for private rocket parts built with fund money | The fund's basic policy is launching from Japan in principle; the bill adds launches of a rocket alone to the permit system | Inference |
| After the H3 failure, the cause analysis was accepted at a ministry-level meeting and flight 9 succeeded, so private interest in the fund's rocket-related themes may depend on launch results | Response status for H3 flight 8 (30 July 2026); result of the flight 9 launch (11 August 2026) | Inference |
