Hi there,

As a result of the outpouring of love and admiration of this post, I decided to write this small commentary on the state of the Chinese military and Taiwanese independence. While I don't directly address the Japanese equipment situation, I came across this paper while researching this question you posed for me. In particular, on page 5:

Despite the challenges [of 5th generation fighter development], the acquisition of next-generation platforms is an essential step forward in enhancing the JASDF’s air-superiority capabilities, particularly given that existing units are overburdened by operational demands.

Furthermore, on page 6:

However, the issue with advancements in C4ISR capabilities is vulnerability to

attacks from within the same domain, such as cyber and electromagnetic pulse

(EMP) attacks. Moreover, there is uncertainty over whether the acquisition of

and upgrades to ISR assets will be sufficient to keep pace with regional developments. In particular, Chinese and Russian modernization programs that incorporate stealth capabilities, as well as North Korea’s diversification of its military capabilities (including a new class of submarines capable of launching ballistic missiles), pose new challenges for the JSDF. These diversifying challenges and the increased operational tempo will make it ever more vital for the JSDF to collect, process, and deliver decision-quality information in minimal time to enable it to take the right action.

Additionally, I want you to look at the Chinese Navy's three carriers and tell me that the two helicopter destroyers that Japan has can stand up to them. I wouldn't bet on them being able to right now, and by the time they're ready with F-35Bs it is likely that the Fujian will have a wing at least partially comprised of their new J-35.
