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. The CubeSat was to take measurements of the radiation environment near the Moon as well as on the lunar surface. Omotenashi is a Japanese word for "welcome" or "Hospitality".[2][6]

OMOTENASHI was one of ten CubeSats launched with the Artemis 1 mission into a heliocentric orbit in cislunar space on the maiden flight of the Space Launch System (SLS), that took place on 16 November 2022.[3][7]

After deployment from the Artemis I second stage, JAXA reported unstable communications with the spacecraft.[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.[9]
