The problem is, they are poor travelers.
Unlike their Korean counterparts, I feel the Japanese have a superiority complex which rules out any form of real dialogue.
Here in Indonesia, you rarely see the Japanese venture from their own circle, whether it be schools, supermarkets, or territory.
The beauty of the "Korean Revolution" is that they have embraced "multiculturalism" whilst stubbornly sticking to the teachings of their own culture by NOT allowing the government, the media, the UN or even education to dictate to them who or what is Korean.
One of the students in an international business class I was taking worked for a small corporation that did business with the Japanese. A Japanese company bought them. The student asked our professor what changes he thought would take place at the company. The professor listed the various jobs where the American employees would be fired and replaced by a Japanese employee. He also listed the time frame involved in this. He turned out to be 100% correct. The Japanese do move to other countries if it helps their nation. They are very polite, but they have no interest in changing their national identity.
