During today’s Japanese government (MEXT)’s committee meeting on space development, JAXA has announced they are planning a dedicated test flight of the H3 rocket’s “-30” variant with 3 LE-9 engines on the first stage and no SRBs during Fiscal Year 2025.

The launch will target a Sun-Synchronous Orbit (SSO) with a dummy payload as the main payload, and several hitchhiking satellites planned as well. Some of the candidates include:
