How do most Japanese people view Middle Easterns?

Question:

How do the majority treat them.

Answer:

I have met a few Americans and Canadians of Middle Eastern descent and a few Iranian nationals over the years. I had a colleague from Iran (not a drug dealer) at one job, and he would talk about things like this.
In his opinion, and I tend to agree, the Japanese do not see the world through the Anglo-Saxon lens. England and the USA, as parts of Western Civilization have a long, long history of interacting with the Middle East and all of the cultural, historical, and religious baggage. There have been conflicts and ongoing violence and mutual misunderstanding between common Americans and common Middle Easterners.
There is less of this, very little of this, with Japan. Japanese have very little historical contact with the Middle East, and so there is a clean slate. Many Japanese visit Egypt to see the Pyramids and the museums, or have traveled in Malaysia and Indonesia, so they are somewhat familiar with the faith of Islam.
There are people in Japan that hate foreigners, no matter what country, but you won't find too many people who single out Middle Easterners for discrimination, or Japanese people who hold negative stereotypes.

(The Iranian thing was a long time ago and pretty much confined to the Kanto Area. Besides, the customers of the drug sales were Japanese! So how the hell are you gonna blame the Iranians? They are just the businessman. If you want them to go away, stop buying drugs.)
