POTENTIALLY OFFENSIVE, SO I RECOMMEND DISCRETION.
Back in 1994, I took a recreational lecture course in Tokyo on the history of Japanese floral arrangement. The lecturer was, I gathered, high up on the Ohara School, and he'd been in that circle perhaps longer than I had been on the planet, but he never mentioned his academic credentials that's supposed to impress Japanese audience; he was just the nicest, humblest, but a darned smart man; I still have all my notes but I should have had a tape recorder to capture all his insights.
Among other things, he directed our attention to the newer direction of Japanese history, knowing the Japanese imperial family has Korean descent seeing Japan as a dumping ground of the powerful and influential that fell out of favor every time China/Korea had a regime change. He referred often to historian Amino Yoshihiko who started this "movement" studying regular people's lives in Medieval Japan, so no official documents and high literature, but things we used and pictorial description of regular folks. The Amino/Folk history showed a very different picture of the Japanese poeple than what was normally accepted even by ourselves. And this, in the 80's and 90's, was still a rather bold view.
To say the Imperial family is from Korea is similar to saying Jesus was Jewish; it's factual, but some take offense. The course opened my eyes, thankfully, to how much our history was rewritten to deify the Imperial family, and that it took place not recently but most probably over the last millennium-plus. I also feel reassured to learn more links to China/Korea. (By the way, anthropologists still don't know where the "race" calling itself the Japanese came from - I think there are at least three theories; I wouldn't be surprised if all of them are correct. )
In 1994 we were well into the Big Recession that started around 1990, although the government needed a bit longer to get its giant head around it. We also had a rapid succession of major Imperial events: a funeral in '89, weddings in '90 and '93, after a 30 year absence of such pomp and silliness, (the last one was a wedding in "59), and gazillion tax yen went into these shows.
The lecturer calmly told us to look back on our history, that it was when things were dire for the masses that what see call art/culture flourish. I've been in New Zealand since the end of 1994 so I don't know about the latest recession culture in Japan. But if we're heading towards a world recession, you and I should capitalize on it.
