Tribe and Religons

Hi,I agree with Airi,too. As she say, Japanese don't think about tribe because of the island country.And also I think the reason why they so is because Japanese are not interested in religion.Some of us belong to religion like Christian, Buddhist, Islam, Jewish and so on but almost all of us do not.Not to believe in religion is strange from foreigners..When I went abroad, it is one of my culture shocks.Talking about religions, I told I don't believe any religion, foreigners said it was strange .Even we are not into religions, there are needs to understand them and have knowledge about them.When we visit foreign country, we should obey the rule of the country. And the rules are often relate to the religion.Why does not Japanese concern about religion compared with foreigners? Does it have something to do with island country?It is very difficult question,isn't it?;(((
