On the surface Japan can seem like it has some things in common (comparable) with the West; however, it's more or less comparing superficial manifestations.
1. Japan while you will see 'international' this and that everywhere and people are taught English from an early age, Japan is very insular (geographically, obviously and mentally) and inward looking (provincial not reflective) and hardly international. People (employees) in the international depts can't expect to rise much within an org. --with few exceptions). All talk and no walk.
2. Japan is very xenophobic (not just a little like Italy might be or France might be about undocumented Roma or Albanians). This could be traced back to how Japan dealt with foreigners (and trade) back in the Edo period as exemplified by Dejima island. Foreigners (dutch) were relegated to an island and had to be back by sundown and could not leave. This attitude has not changed in over a hundred years. 3rd generation Koreans are still considered foreigners (and they must assume a Japanese name, and oddly none the less considered foreign). The foreign population in Japan is actually on the wane for various reasons (economic and also people just get tired of the politics)
3. Japanese industry found their stride in the late 60s; however, few have revisited their assumptions, systems, technologies, methods, etc. For an example, look at their film industry. Almost complete implosion due to stagnation.
4. Conformity. While on the surface these niche 'diverse' groups would seem to indicate break with conformity, it does not. As someone observed, these movements and subcultures are de-coupled from politics, completely.
That's just the beginning. There are many other reasons a 1:1 comparison with the West is not helpful.
There is a kind of parallel withe the US. It's the maturity regression. However, while many in the US recognize and decry the eternal adolescence of American adults (viz toilet humor, frat culture), in Japan it's rather infantilization (viz Hello Kitty, stuffed animals, Pokemon --whose main audience are adults, not children).
Edit: I guess what I mean is that one would extrapolate Japan onto the West at one's own expense (of understanding). In this agree with Japan --they are unique, in this regard.
