I was just about to ask him the same thing. I've read about another, bigger design optimized for the F-35, but I don't know how serious they are about it.
It is in the design phase. And we are very serious about it.
The plan is to maintain the 2 units of the Hyuga Class Light Carriers, 2 Units of the Izumo Class Light Carriers, and 2 Supercarriers (planned) for the JMSDF Combined Fleet.
