These days in Japan, some Japanese people think of K-pop and AKB as pop culture. But at the beginning that they appeared in TV or other events, almost all of people didn't know them and were not interested in them at all. Their dance,songs,and looks are very similar to those of past. Two years ago, though they were not popular, they appear on TV suddenly and advertised various things. Since they appeared on TV, not only I but also other people felt that Japanese TV program are not interesting at all and many people don't watch TV. Some Japanese people are tending to follow fashions which are created by TV companies without knowing that that fashions is a false.
