how did the breakup of the central government in japan lead to changes in feudal Japanese society?

Answer 1

I think you have things backwards. Until the modern "central government", the closest thing to a "central government" that Japan had was because of Japanese feudalism, which prided itself on not changing.

Consider some of these:

Answer 2

That's not a good idea to do. I mean if you wanted to adopt a Japanese name for business reasons or just want a name change thats a different thing. But to change your name to appear more "Japanese" is just kind of wrong. Even Japanese-Americans or Japanese born and raised outside of Japan are not treated as Japanese in Japan. They are also considered outsiders. Even those residing in Japan all their lives but don't LOOK ethnically Japanese or happens to be half Japanese will not be completely accepted as a Japanese. I mean of course technically all those living in Japan are Japanese nationals, but I think this is going more into the ethnic spectra. You can adapt to their culture and live the Japanese way, but you will never be seen in their eyes as a native Japanese. It's just a fact. And why would you want to change who you are ethnically? I feel there is an underlying problem going on here. You can always be one with their culture. But that does not require you changing yourself. Peace be with you.
