OMOTENASHI (Outstanding MOon exploration TEchnologies demonstrated by NAno Semi-Hard Impactor) was a small spacecraft and semi-hard lander of the 6U CubeSat format intended to demonstrate low-cost technology to land and explore the lunar surface.

[8] On 21 November 2022, a Twitter message sent by JAXA reported that further attempts to communicate with the lander, which was scheduled to begin its landing sequences that day, had been ended.

After measuring the radiation environment as it approached the Moon, OMOTENASHI's lander module was planned to perform a semi-hard landing on the lunar surface.

[2] OMOTENASHI was to use a cold gas thruster to enter a lunar-impact orbit, and a solid-rocket motor for the landing phase.

[5] The orbiting module was planned to enter at a shallow flight-path angle of ≤7°, and to be ejected when the solid-rocket burn begins the deceleration manoeuvre.
