Close view shows channel-wall nozzle (with reinforced ribs?)

So since the outside of the nozzle appears to have a flat surface, the assumption is that it uses channel wall cooling.
Mitsubishi Heavy and JAXA aim to launch a prototype of the H3, the H-IIA's successor, in fiscal 2020. The goal is to slash costs to around 5 billion yen ($45.3 million) and the time from order to launch to about one year, using shared parts and components sourced from the private sector. The rocket will also be able to be fitted with different numbers of solid rocket boosters to adjust thrust capacity."In both price and reliability, the H3 will put up as good a fight or better" than competitors like SpaceX, said Naohiko Abe, Mitsubishi Heavy's senior vice president in charge of space systems, adding that he hoped to launch two to three satellites per year.
