Yes.Don't forget the , 6 LCACs, AAV7s and the V-22s that Japan had acquired.
Japan has those three Osumi LPDs that can take the LCACs, not to mention the AAV7s.
The JMSDF is going to have a very nice amphibious and air assault capability with the Osumis, Hyugas, and Izomos.
I have always been surprised that the JMSDF dd not have a few smaller LST or type vessels. As it is, with one Osumi and one Hyuga dedicate to amphibious and air assault, the JMSDF could place a credible landing force ashore.
As I understand, the Osumi and Hyuga can each carry, in addition to their crews, about 350 troops. Is this correct?
