How much of (modern) Japanese culture comes from Western countries ?

[kokusu]

As for homosexuality I would say that this is a mostly a Judeo-Christiano-Islamic taboo, not a "Western" one. Ancient Greeks and Romans had no taboo about it. Many great leaders (Alexander the Great, Julius Ceasar...) were homo- or bisexuals. The recent acceptation of gayness has happened mostly in places where Christianity has become much weaker. In the US (the most Christian Western nation), we are not near to see a legalisation of gay marriage.

While Judeo-Christian-Islamic religions find their origin in the Middle East, I would argue that wide dissemination and cultural enforcement of Chrisitian views towards homosexuality originate in Eurpoean Christianity. Note, I am not saying the belief that homosexuality is wrong didn't exist in the original religious foundations of Christianity back in the Middle East, I am simply saying the widespread dissemination and enforcement of that belief was purpotrated by the Western adherants of Christianity where Christianity itself has become culturally embedded.
Furthermore, views towards homosexuality differ from culture to culture and from era to era. Certainly even within 'Western' cultures views regarding homosexuality vary (take for example the 'homophobia' of the U.S. versus the right to 'gay' marriage in Canada). I am not saying that a single view of homosexuality is representative of all Western cultures nor that Japan's views regarding sexuality over the last century necessarily make it a Western culture. I am simply saying that much of Japan's views regarding were received from the 'West' in the early part of the 20th century, Christianity, IMO being a Western influence upon Japan. This I think answers the question that this thread asks: "How much of (modern) Japanese culture comes from Western countries?" I am pretty certain that Christianity and its taboos were not a Chinese influence upon Japan.
As to how intertwined "a mostly a Judeo-Christiano-Islamic taboo" affected Western culture and thought which in turn had an influence on Japanese culture:

"Even as Meiji medical authorities emphasized the phsyical and social dangers resulting from male-male sexual behavior, they sought a basis for such behavior in the laws of biology . . . Here, Meiji sexologists relied heavily on the research of their Western colleagues, who were busily redefining the construct of "homosexuality."" (Pflugfelder, Gregory M., Cartographies of Desire, p. 248, University of California Press (2000))

Here I completely disagree. The constitution was imposed by the US, but it is not at all representative of "Western" systems.

I am not saying that the Japanese constitution is representative of "Western" systems, only that the Japanese constitution came from a Western country, namely the U.S. Again, isn't the question, "How much of (modern) Japanese culture comes from Western countries?", not how much does Japanese culture mimic Western culture?

Parliamentary monarchy was copied on the British system in the late 1800's. It's not the Americans who introduced it in 1945.

Again, what I am saying the U.S. brought to Japan post-WWII was the Japanese consitution. I already stated (in my original post) that there were other influences, such as from Germany.
As to the influence of the modern Japanese constitution as prepared by SCAP:

"On February 10, the sixth day after he had convened his constitutional convention, General Whitney transmitted the draft of a completely new constitution to the supreme commander. He pointed out that this draft embodied the considered and collective view of the members of Government Section, "representing nearly every form of American political thought," and that it had been written after taking the historical development of the Japanese constitution into consideration and giving studious attention to American and European constitutional principles." (Dower, John W., Embracing Defeat, pp. 372-373, W.W. Norton & Company / The New Press (1999).

So the 1945 constitution was not "Westernisation"; it was purely "Americanisation".

Finally, regarding Article 9 and Japan's pacifism, this can certainly not be regarded as Westernisation.

Once more, I am, in line to what this thread inquires about, talking about influences from the West and Western cultures, not necessarily a complete Westernization or absolutely mimcry of Western cultures. That no Western country includes a pacifist clause in its consitution does not negate the fact that Japan received its pacifist clause from the West.
Also, I would note that the SCAP produced constitution for Japan took into consideration American and European consitutional models. So to say that the 1945 consitution was simply a form of exclusive "Americanisation" I think is not wholly accurate.

What did you have in mind in the "and so on" part ?

*rests his head wearily against his monitor* I probably meant . . . forks? Heh. Sorry! I really have enjoyed our little debate here, but I had to get up early to dig through my research notes, lecture notes, articles, and books to make sure I had documentation for what I was writing . . . I love this kind of dialogue, but I'm wiped out right now! I think the 'so on' part was mainly in reference to the rest of the constitution in general, as a document. While not every Japanese may know all of their constitution by heart, as a document, I think it has had considerable impact upon their contemporary culture.
One question that would arise from this: If Japan did not have the pacifist clause in its constitution, would military spending have been greater leading to less overall economic development and prosperity? This is an important question when you consider the impact of Japan's spectacular economic recovery and growth on its culture in the latter half of the 20th century.

Pheh . . . I think I'm just rambling now, so time to go . . .
