There also were many arrested at the Expo for "streaking.

Next you are going to claim that streaking like suicide bombing has its origins in Japan. Is that correct?

Street performance piece seen by two friends in Umeda, Osaka a few weeks ago: a large funk band all dressed in orange jumpsuits, like the ones at Guantanamo, all doing the synchronized Hitler salute.

Look, man. A Japanese person did the first suicide attack in the modern Middle East conflict. Whether or not that led directly to more suicide bombings in the 80s is another issue, but it's not like I made up the idea out of thin air.

it's also a year of the Mishima's art piece, with the expo going on I understand why the word 'embarassed' is often put to describe feeling the Japanese had about it ... Marxy, I was told Southern Korea is now /mentally, socially etc/ what Japan was 30 years ago- what do you think about it?

Well anyways the link with streaking may not be as far fetched as it may sound, as evidenced by this item about the Les Rallizes Denudes/Hadaka no Rallizes.

Was Japan in the '60s like South Korea now?

Hmm... I've never been to SK, so I don't want to feign perfect knowledge on the subject, but Japan was certainly a very polluted, dark, and boring nation until the mid-70s. Their economy was huge, but consumer culture had only started to kick in by the end of the high growth period. Income inequality, however, was very low, so they were all in the same boat. I think this is very different than present Korea, which still has a social structure similar to pre-WWII Japan.
