I think I don't like Japan

It's been 9 months since I came back to Japan.

At first, I was so happy that I was able to see my family and friends, and yeah, able to have Japanese FOOD! (I think it's the most delicious and healthy food in the world)

But now, I don't like Japan because people haven't changed for so long time, they're excited the same thing as 3 years ago, girls still love to copy everything that's called the BOOM, and guys still read Manga in a train... I've changed in a lot of ways, I've been more curious about anything than before, I'd love to know more things, I want to study more and have more carrier, but normal (about 80%) Japanese aren't like me, it makes me so sad, and I loose any interests for Japanese people...

I need something different from Japan.
