I understood it clearly that the Japanese boom that we've experienced for nearly 10 years since 1999 had already died down. This country('s culture?) started fading out from Magi and other foreigners who got crazy with Japanese boom at its height and began to upload their vids. This country will be tumbling down rapidly and hope of a light must grow fainter. Magi and other foreigners, who were flattered in the middle of the Japanese boom, who have selected Japan, would feel a pain and regret at its cultural rise and fall, wondering if they made a mistake.
In addition, Magi should have found that Japanese are such disgusting, teasingly inclined, corrupt at hearts, shitty-people. So she must have been astonished at the fact and came to abhor Japanese for sure.
1.That Japanese writing doesn't sound like a native at all. (But the poster should have at least writing skills of Japanese to some extent.)
2.The observation is partially true, but I think "Japanese boom" itself was made by Americans and Chinese to rob us of our contents on the net and to f**k with them. That is not a boom but plunder. In that point of view, they'll keep on f**king until their countries pull them up.
3.About Japanese decline, yeah it must happen in all developed countries for sure. Especially in this recession. Cultures are no longer free from their economy in open market societies. The foreigners who'd played tricks on themselves might get disillusioned with Japan. But it's also true that most of Japanese inside have never experienced that boom. If you've understood exactly what Japanese culture is, it'll never die down nor be gone. So it may be a problem for Koreans or Chinese who are managing "Sushi Shops" outside of Japan. And I guess that's all for this matter.
4.Then, about Japanese national character, the poster is, certainly, a racist. Nothing more to say.
