Promise Ledger
Lunar lander company (HAKUTO-R). These are the dated public commitments by ispace and its people that we could source to a primary, with what happened.
3 entries: 2 missed; 1 revised.
Plain counts, not a grade or a ranking. A short record is not a complete one. Updated Sep 28, 2026; each entry shows the date it was last checked against its source; scoring rules on the methodology page.
This first release is a selection, and a short record is not a complete record. Each programme milestone enters the ledger at its earliest dated public commitment we can find in a primary source, for governments and companies alike. Later dated commitments for the same milestone are shown on that one entry as a revision chain, oldest first, rather than as separate entries.

“the earliest scheduled landing date for the HAKUTO-R Mission 1 Lunar Lander is set for Tuesday, April 25, 2023, at 16:40 (UTC).”
Said . Source: ispace: ispace Announces Earliest Scheduled Lunar Landing Date for HAKUTO-R Mission 1 (Apr 12, 2023, paragraph 1)
Context: The release lists alternative landing dates of April 26, May 1 and May 3, 2023; the deadline uses the last of these.
Outcome: The landing sequence ran on 2023-04-25 UTC (April 26 JST). ispace reported that the lander estimated its altitude as zero while about 5 km above the surface, descended until its fuel ran out, and "is believed to have free-fallen to the Moon's surface"; it attributed the altitude error to its software.
