While the H3-32 would have provided greater performance, JAXA cited SpaceX's experience with their Falcon 9 rocket, which routinely lifted commercial communications satellite payloads to less than the gold standard geostationary transfer orbit (GTO) of 1,500 m/s (4,900 ft/s) of delta-V remaining to get to geostationary orbit, leaving the ...

JAXA H3 project manager Masashi Okada called the result “perfect,” saying H3 cleared all missions set for Saturday's flight. ... The H3 No. 2 rocket was decorated with thousands of stickers ...
The H3 left the Tanegashima Space Center in southern Japan at 9:22 a.m. local time on Saturday, the Japan Aerospace Exploration Agency (JAXA) said in a statement.
JAXA's 63 m (297 ft) H3 rocket can carry a 6.5 ton payload into space, more than H-IIA's maximum of 6 tons, and fly more cheaply by adopting simpler structures and automotive-grade electronics ...
When the H–1 was announced in 1986, company representative Tsuguo Tatakawe clarified that it would only be used to launch indigenous (i.e. Japanese) payloads, that only two launches per year could be mounted, and that the launch window consisted of a four-month period in which Japanese fishing fleets were not active (the falling launch boosters may damage fishing nets in the ocean waters).
"The newborn H3 has just made its first cry", JAXA project manager Masashi Okada, who has led the decade-long development of the new rocket, told a news conference.
JAXA uses the H-IIA (H "two" A) rocket from the former NASDA body as a medium-lift launch vehicle. JAXA has also developed a new medium-lift vehicle H3. For smaller launch needs, JAXA uses the Epsilon rocket. For experiments in the upper atmosphere JAXA uses the SS-520, S-520, and S-310 sounding rockets.
