Yaoki
Japanese lunar rover carried aboard Intuitive Machines-2
Yaoki was a Moon rover made by Japanese company Dymon launched on 27 February 2025 by American company Intuitive Machine's IM-2 Athena lander. It landed on the Moon but deployment was not possible as the lander was on its side and the mission ended due to the landers' inability to recharge its batteries.
Yaoki was first announced in 2019. The rover weighs 498 grams (17.6 oz) and transportation to the Moon costs $1.2 million per kilogram.
Name
Yaoki refers to the Japanese proverb 七転び八起き (nana korobi ya oki). This proverb means "To get back up again and again, no matter how many times you fail" (literally: "Seven times falling down, eight times risen up").
Dymon
Yaoki is developed by Dymon Co. Ltd., which is led by robot creator Shinichiro Nakajima. As an automobile engineer, Nakajima also worked on the development of Audi's four-wheel drive system “quattro”, a defining feature of Audi vehicles since the 1980s. Dymon was founded by him with the aim of developing mobile lunar robots and ground robots.
This brief starts where responsible research should: with the source description of “Yaoki” as japanese lunar rover carried aboard Intuitive Machines-2. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as japanese lunar rover carried aboard Intuitive Machines-2. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 4, 2026. The linked authority identifier is Q107463179. None of the 2 selected statements returned an explicit reference. The first chronological checks are 2025 and 2019.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
