Do followers of Confucianism tend to be in favor of monarchies? such as the Japanese royal family?

Forgive me for not being very well read on Confucian philosophy. But based on my understanding, Confucianism is very conservative. And believes more in collective societal progress rather than individual progress. And also believe in preservation of tradition. Sorry if any of that was wrong. But if at least that last thing was correct, does that mean supporters of the monarchy in Japan also tend to be into Confucianism as well?
