it has been quite a long time that I don't  write my blog. my trip in tokyo is neither interesting nor boring,anyway i'm disappointed not to have seen many old places, but spyscrapers everywhere.tokyo is full of energy, the streets, metro are full of people even at 0h!but people are quiet,they don't talk in public place, on the contrary, we Chinese talked loudly in metro, I wonder Japanese might think why Chinese like talking so much:)
