You can't think about the Japanese mental state with normal logic.
Japanese politicians are in fact hereditary aristocrats,they lack compassion for the people at the bottom.Since the LDP has strengthened its power to appoint and remove personnel, those civil servants have become more dependent on the ruling party.
Recently, a senior leader of Japan's police was forced to resign. He is very good at pleasing Shinzo Abe and the LDP regime.This senior leader of the police has personally issued instructions on many occasions, asking the police to act in favor of the LDP. As a result, Abe was assassinated for this excessive flattery:The local police had warned that they lacked the ability to defend dignitaries, and other politicians had abandoned their propaganda activities in the area, but Shinzo Abe was not prevented from doing so.

Therefore, under such circumstances, it is unrealistic to expect the congress and the military to oppose the war.They will prioritize their personal political future. In order to improve its political status, the JSDF is very likely to ask to participate in the war.Casualties? That's not what those who don't have to go to the front need to care about, and the Americans will finish things for them.
From historical experience, as long as the Japanese have a little advantage, they will not consider the gap in strength at all. They took the initiative to attack without knowing the strength of their opponents many times.
This is a national defense strategy book written by four retired JSDF generals:
View attachment 96779
One army general, two air force generals, and one navy general.
They bluntly stated that Taiwan is the most important area for Japan's security(台湾は日本にとって安全保障上の最重要地域である).
Although they have retired, they can also show JSDF's political attitude to a certain extent.
Unfortunately, a number of retired JDSF generals have shown militaristic tendencies and contempt for the PLA.
Those who only care about whether their status will rise will not care about the risks brought to Japan by failure.
