About Japan's Space Industry
Japan is a key player in space exploration and technology, with JAXA contributing to the ISS, asteroid sample-return missions (Hayabusa2), and the H3 launch vehicle. Companies like ispace and Astroscale are global leaders in lunar landing and orbital debris removal, positioning Japan at the forefront of in-orbit services and commercial space innovation.

Space Programs
Government and agency programs associated with Japan
Lunar Gateway
activeNASA / ESA / JAXA / CSA • 2025–2030s
International space station in lunar orbit supporting Artemis surface missions. Gateway will serve as a staging point for crewed lunar landings, deep space science, and eventual Mars transit. ESA is building the ESPRIT refueling module and I-HAB habitation module. JAXA contributing life support. CSA providing Canadarm3 robotic system.
~$5B+ (multi-agency; ESA contributing €1.8B for ESPRIT & I-HAB modules)
SLIM & Lunar Exploration
activeJAXA • 2023–2030
Japan became the 5th country to soft-land on the Moon with SLIM (Smart Lander for Investigating Moon) on Jan 19, 2024. Though it landed upside-down, it demonstrated pinpoint landing accuracy (within 55m of target). JAXA is now developing LUPEX (Lunar Polar Exploration) with ISRO for south pole water ice investigation, and contributing to Gateway and Artemis.
¥18B (~$120M) for SLIM; LUPEX co-funded with ISRO
H3 Launch Vehicle
activeJAXA / Mitsubishi Heavy Industries • 2014–ongoing
Japan's next-generation flagship rocket replacing H-IIA. After a failed first flight in Mar 2023 (second stage shutdown), H3 successfully reached orbit on its second attempt in Feb 2024. Now operational, targeting 50% cost reduction over H-IIA. Key for Japan's independent access to space and launching IGS reconnaissance satellites.
¥197B (~$1.3B) development
LUPEX (Lunar Polar Exploration)
plannedJAXA / ISRO • 2028–2029
Joint Japan-India lunar rover mission to the Moon's south pole. JAXA provides the rover and ISRO provides the lander. The rover will carry a drill capable of penetrating 1.5 meters below the surface to confirm the presence of water ice and characterize its distribution. Toyota is developing the rover's driving technology.
~$500M (joint JAXA-ISRO)
