Japan now has its own helicopter carrier. Japan wants to build its own aircraft carrier and restore the navy's powerful great power ambition during World War II. Unless the US government allows it, or both sides lose after the Sino-US War, Japan takes the opportunity to build an aircraft carrier. Second, China's military strength exceeds that of the United States, and the United States will allow it to build an aircraft carrier as an ally of the United States to balance China. So I personally think that Japan will not build an aircraft carrier in the next decade, but will secretly develop aircraft carrier technology.
