Building up on the site's recent article about H-III (or H3) final certifications and road to first flight:
https://www.nasaspaceflight.com/2021/09/japan-h3-engine-certification-first-flight/
I believe there's no thread about this maiden flight yet. The development of the rocket itself is mostly wrapped up and launch processing perations have been started, even if there are non-standard operations (not the least finishing the LE-9 certification) being performed - these shouldn't be included in the "H3 development thread" in my opinion.

So opening up with the S1-S2 stacking just announced today:

This is very likely a place holder for NET January 2022, itís possibly using one of the launch databases I help to maintain:

SFN Japanís H3 rocket further delayed by engine woes, January 24
First launch delayed to Japan Fiscal Year 2022 = April 2022 through March 2023.

Quote
[Masashi] Okada[, JAXAís H3 project manager,] said a series of nine combustion tests convinced JAXA that it could stick with the LE-9ís current combustion chamber design for H3ís first test flight ó carrying Japanís Advanced Land Observing Satellite-3 (ALOS-3) ó by sacrificing some performance. For H3ís second test flight, carrying ALOS-4, Okada said JAXA and MHI would switch to a 3D-printed combustion chamber they think will solve the problem for good.
