What Dymon does
Dymon Co., Ltd. (株式会社ダイモン) is a Tokyo-based, privately-held Japanese aerospace company founded in 2012 that designs and operates YAOKI, the world's smallest and lightest lunar exploration rover at approximately 0.5 kg — roughly one-tenth the size of conventional lunar rovers. The rover is engineered for extreme lunar conditions, with carbon-fiber-reinforced-plastic construction (sourced via partnership with Mitsubishi Chemical and UCHIDA) that withstands 100G shock impacts, falls from 100 meters, and temperatures below −100°C, and is designed for low-mass economics given lunar transportation costs of approximately ¥100 million per kilogram.
The company operates three business pillars under the Project YAOKI umbrella: (1) a primary lunar robot business targeting government and institutional buyers via NASA's Commercial Lunar Payload Services (CLPS) program on the Intuitive Machines Nova-C lander, plus a new ispace payload transport agreement; (2) a terrestrial ground-robot business adapting YAOKI mechanical IP into four-wheel ceiling-inspection robots; and (3) an education and entertainment segment offering YAOKI driving experiences, STEAM workshops, and VR lunar exploration content. Project YAOKI-1 successfully landed on the moon in March 2025, making Dymon the first Japanese private company to achieve lunar surface operations, and Project YAOKI-2 is scheduled for the second half of 2027 with two rovers.
Revenue is generated through multi-year mission and technology service contracts, corporate sponsorship partnerships (current roster includes Mitsubishi Chemical, Punch Industry, JAOPS, Tokio Marine Nichido, Central Engineering, and others), hardware sales of rovers and ground variants, and workshop/VR service fees. Pricing is mission-specific and not publicly disclosed. Dymon remains a small startup with fewer than 50 employees, with disclosed capital consisting primarily of a ¥100 million sponsorship round in March 2021 from five corporate backers (Nihon Unist, UNIT, Pixies, UCHIDA, and Kokko Shisetu Kogyo).

Dymon product offering
Product offeringCore offering
Dymon designs, develops, and manufactures ultra-compact lunar exploration robots, with its flagship YAOKI rover recognized as the world's smallest and lightest lunar rover at approximately 0.5 kg. The company also extends the YAOKI platform into education and entertainment-related offerings.
Product overview
Dymon operates Project YAOKI, a lunar exploration initiative with three business pillars: lunar robot business, terrestrial robot business, and education/entertainment business. The core product is YAOKI, the world's smallest and lightest lunar rover at approximately 0.5kg, which achieved historic lunar surface arrival in March 2025 as part of NASA's CLPS program. Related offerings include a 4-wheel ceiling inspection robot adapted from YAOKI technology for Earth applications, VR lunar exploration experiences developed with Cross Device, and specialized deployer transport cases with CFRP materials from Mitsubishi Chemical. The company is preparing for Project YAOKI 2 (PY-2) in late 2027 with plans to deploy two rovers for lunar resource discovery.
