This test marked the first launch and landing test conducted by Honda with an aim to demonstrate key technologies essential for rocket reusability, such as flight stability during ascent and descent, as well as landing capability. Through this successful test, Honda achieved its intended rocket behaviors for the launch and landing (reaching an altitude of 271.4 m, and landing within 37cm of the target touchdown point, with a flight duration of 56.6 sec), while obtaining data during the ascent and descent.

Date/Time: June 17, 2025. Launch time: 16:15
Since 2024, Honda has been safely conducting engine combustion tests and hovering tests for its reusable rockets in Taiki Town in Hiroo District, Hokkaido, Japan. As with all previous tests, Honda conducted this launch and landing test while placing the highest priority on safety and with the understanding and cooperation of local authorities and residents.
Specific safety measures taken for this test
- A restricted area with a 1-kilometer radius was established. During the test, access to the area was restricted through the installation of signs and gates, as well as the deployment of security personnel.
- The restricted area was defined by calculating the potential area where the rocket could fall to earth in the event of a thrust cut-off and by adding a sufficient buffer zone (safe distance calculated based on the guidelines set forth by the Cabinet Office of the Government of Japan) that would cover the potential area where a blast wave, debris dispersion, or fireballs could impact in the event of an explosion within the potential fall area.
- The experimental rocket was equipped with a safety system to prevent deviation from a pre-defined flight corridor, speed and attitude conditions, ensuring no impact beyond the restricted area.
Honda initiatives in the areas of rocket research
As announced in 2021, Honda has been pursuing research and development in the field of space technologies while viewing it as a place to take on challenges to realize the “dreams” and “potential” of people worldwide while leveraging its core technologies. Honda has the aim to enable people to transcend the constraints of time, place or ability and make people’s daily lives more enjoyable. Examples of Honda initiatives toward creating new value in the ultimate environment of outer space include research into a circulative renewable energy system, key robotic technologies for use in outer space and reusable rockets.
Inspired by the dream of young Honda engineers who wanted to build rockets by utilizing core technologies amassed by Honda through the development of various products, such as combustion and control technologies, Honda started rocket research based on the belief that it has the potential to contribute more to people’s daily lives by launching satellites with its own rockets, that could lead to various services*3 that are also compatible with other Honda business.
In today’s world, vast amounts of data are consumed, with the growing expectation for greater utilization of a data system in outer space through expanded use of satellites. In light of this trend, the need for satellite launch rockets is also expected to increase in the coming years.
In this market environment, Honda has chosen to take on the technological challenge of developing reusable rockets by utilizing Honda technologies amassed in the development of various products and automated driving systems, based on a belief that reusable rockets will contribute to achieving sustainable transportation.
Although Honda rocket research is still in the fundamental research phase, and no decisions have been made regarding commercialization of these rocket technologies, Honda will continue making progress in the fundamental research with a technology development goal of realizing technological capability to enable a suborbital launch by 2029.
