I can't understand about politics :'(

     There many difference about politics between Japan and America. I’m not interested in politics so I don’t know about politics. First, in Japan head of state is prime minister but in America head of state is president. I don’t know what is the difference between a president and prime minister so I searched. According to the site the differences between a president and a prime minister largely depend upon the country to which one is referring. A president and prime minister may have relatively equal powers, but this again is dependent upon the type of government a country employs.
Second, in Japan we can vote from 20 years old, in America they can vote from 18 years old. The diet discussed about the age of we can vote before. Someone suggested we can vote from 18 years old but it didn’t change because Japanese considers adult over 20 so 18 considers child and they can’t think about politics. I think so too because I’m 18 years old now and I can’t understand about politics and I don’t want to learn about politics.

Third, about immigrants. In Japan Currently the constitution of Japan defines voting rights as only for citizens. There are many countries immigrants can vote in the world for example Belgium, Netherlands, Slovenia, Lithuania Sweden, Denmark...etc. In my opinion we need not to prohibit immigrants to vote. If the government prohibit them seems to discriminate in racial. To vote only Japanese it will be a parochical viewpoint. Japan needs opinion not only Japanese. From foreign people point of view, Japan might be better than now.
　 Recently Japanese prime minister is changing a lot about per a year. Last change is 2 of September 2011. This month!! I don’t understand why they change so. I think it’s too hard for children to remember the name all of them. I can’t remember the name even now. Japan is crazy!! Japanese people hope anyone who can rule a country for long time and who has ideas everyone can live happy.
