Is there any real benefit to the Japanese even if they can build up
a naval airpower that rivals the USA ?
As matters stand, China has developed her military to a higher
technological standard than before, even if it is not at par with
other Western Powers.
Its aeronautical industry has produced the J-7 and J-10 planes
that are far superior than the old MIGs in the Chinese PLA
inventory.
Even if these newer aircrafts are no match to the
advanced US F-22 or even the F-35, the vast numbers produced
for the Chinese Air Force will overwhelm the limited number of
aircrafts launched from any expeditionary force of aircraft
carriers.
In the first place, even if the US industries push for a bigger
market for the F-35, will the public opinion in the USA or the
other Asian neighbors allow Japan to continue along this
path ?
Will Japan's own citizens allow such a development
after suffering the consequences of the Right Wing Japanese
militancy that led to the atomic destruction of WW-2
?
China's quest for an aircraft carrier is not to threaten Japan
specifically, but as a tool to counter what they see as the
unchallenged threat by the US carrier fleet that sail unopposed
into the Chinese exclusive territorial economic zones
that is recognised by all nations to be 200 nautical miles from the
coast.

Aircraft Carriers and US Military Strategy’
Let just assume logically that China doesn't need aircraft
carriers to defend its sovereign airspace over mainland China.
Hence, their carriers are gonna go out to sea to do their
business elsewhere.
A few places spring into mind. Taiwan is one of them, but
it seems like China's policies towards Taiwan is softening as well.
Another place of a little more concern would be the Spratly
islands. All of the parties claiming the islands are unlikely
to be able to project airpower over the islands without some form
of naval aviation. Without US carriers nearby, a Chinese
carrier task force would dominate the area.
This does bring into mind the Vietnamese acquisition of
submarines doesn't it?
Similarly, even if the Japanese Hyuuga was to come with a full
compliment of F-35s, it would definitely not go knocking on the
door of a state with a modern and competent air force. That
is probably not going to be Singapore.
Again, if we assume that carriers aren't required to defend
homeland airspace, those carriers would probably head over to
either disputed areas, or states that do not have a modern and
competent air force. In that, it would be the Senkaku
Islands, or North Korea. As far as I can see, it doesn't seem
like the Japanese would have any interest in South East Asia and
there is little they can do with just a few VSTOL carriers without
a power navy and sufficient troop strength.
