Japan Advances Reusable Rocket Program With Successful Test Flight
TOKYO-Japan’s space agency successfully launched and landed a prototype reusable rocket on Saturday, completing its first lift-off and landing test as the country seeks to develop lower-cost launch technology and strengthen the competitiveness of its space industry.
The Reusable Vehicle eXperiment (RV-X) prototype was launched from the Japan Aerospace Exploration Agency’s (JAXA) test facility in Noshiro, in Akita prefecture. The vehicle climbed to an altitude of about 10 meters (33 feet), remained airborne for roughly 40 seconds and then landed safely at the test site.
JAXA described the demonstration as the first successful lift-off and landing test for the prototype, marking an important step in the agency’s efforts to develop reusable launch systems that can reduce the cost of access to space.
Takashi Ito, who led the launch project, said the successful flight represented the culmination of extensive preparation. Speaking to reporters after the test, he said the agency was relieved that the prototype had completed the launch and landing without incident.
Ito said engineers would analyze flight data before making a final assessment of the experiment but added that he was confident the mission had produced valuable technical information to support future development.
Reusable rocket technology has become a major focus of the global space industry because it allows expensive launch hardware to be recovered and flown repeatedly rather than discarded after a single mission. The first stage of a rocket is typically its most costly component, making recovery and reuse a significant way to reduce launch expenses.
Most conventional rockets are designed for one-time use, with spent stages either falling into the ocean, burning up in Earth’s atmosphere or remaining in orbit as space debris after completing their mission.
The field has been led by the United States, where SpaceX has operated its partially reusable Falcon 9 rocket since 2017, demonstrating repeated booster recoveries and significantly lowering launch costs.
Japan’s test came one day after China announced its first successful reusable rocket landing, highlighting growing international competition in reusable launch technology as major space powers seek to expand their commercial launch capabilities.
Japan’s private sector has also begun making progress in reusable rocket development. In June 2025, a subsidiary of Honda became the first Japanese company to successfully launch and land a reusable rocket prototype.
The Japanese government and domestic aerospace industry have placed increasing emphasis on improving the country’s position in the global launch market through advances in rocket technology and more cost-effective launch systems.
JAXA has also continued developing its flagship H3 launch vehicle. The rocket completed a successful mission in June, months after an earlier attempt to place a satellite into orbit ended unsuccessfully, as Japan works to establish a more reliable and internationally competitive space launch capability.
