Aircraft Carriers III

... I don't see why it is somehow a unique issue to aircraft carrying platforms.
your "unique issue" of "aircraft carrying platforms" is called power projection:

aircraft carriers are able to sustain war-fighting activities over Oceans of the World, from Pearl to Aleuts to Guadalcanal to Colombo,

and Japan should not be allowed to sustain war-fighting activities over Oceans of the World, from Pearl to Aleuts to Guadalcanal to Colombo
 
I read somewhere that it was only a political move and that the military branch was never actually asked about the feasibility or viability of this project.

Japan's plan to remodel Izumo-class carriers: Needed upgrade or mere show of force?

"In fact, in announcing the new National Defense Guidelines last December, Iwaya, the defense minister, admitted that the Izumo conversion plan was not based on requests or proposals from Self-Defense Forces leaders, but was adopted based on a top-down decision among high-ranking government officials."

I think you don't want me to comment, but give me a sign if you do

…. and so would be submarines and destroyers.

I think you know an aircraft carrier is the power projection platform

I do not disagree that historically carriers are often associated as a power projection platform. However how it had been used in the past doesn't mean it is necessarily and exclusively a power projection tool. There are credible alternative usage in the form of extended perimeter defense which is the main driver behind the case of Japan going this route. The Senkaku islands are a far way from land base aircrafts and would require extensive logistics support to patrol the outer perimeter. A multi purpose destroyer with F-35B will enhance security to the outer perimeter of Japan's jurisdictional territory - an activity that can hardly be argued as offensive.

OK I'm going to keep an opposite opinion from the rest of long-time members here,

as I think Japan should not go back into aircraft carriers (no matter if spin doctors would then call them 'defensive aircraft carriers', 'non-offensive aircraft carriers', 'through-deck cruisers' or what ever else),

because
  1. the US forces in the Pacific should take care of a hypothetical Senkaku or any other Japan-related crisis, and because
  2. in case Japan went back into aircraft carriers, even bigger arms-race would begin in the Far East
(just strategic considerations above, I set aside what would happen to the rest of a relatively small Japanese military budget, what the CONOPS would be like what if one of the carriers off a remote hostile island is hit and burning -- what do you do then? and other questions)
