Read why Japan doesn't have these problems.
Snip: Japan has put strict restrictions on Islam and ALL Muslims.
Japanese cops also pack heat in a virtually gun free society.
When our company wrapped up our last project in Iran, he made one final trip home to say goodbye to his family. He said he couldn't live the lie of even pretending to be a Muslim anymore.
Because the Japanese are not afraid to profile, it also means you can show up to the airport 20 minutes before a flight and still make it. This actually happened to me once when my airport bound bus got stuck in a traffic jam. I called the airline and they told me to relax. They would get me on the flight even if I showed up with only 10 minutes to spare.
They say Japan treads lightly with Islam because they need the oil so badly. In reality, the Islamic world treads lightly with the Japanese because they need hard currency so much worse.
This really came home to me when I was in charge of oil contracts for our company for a few years. Everyone wanted to sell us oil including places like China and Singapore whom you don't even think of as oil exporters. In fact, the only Middle East contract for oil I ever bought was from the U.A.E., the only relatively trustworthy Muslim country in the whole region (with the possible additions of Bahrain and Qatar).
