The Japanese group showed up today.

I don't know why but I sometimes encounter a number of Japanese people. Today, I just encounter a Japanese group. They got off at the train station, and they were behind of me somehow. I wonder if they have family members who are working for the police or the Soka Gakkai member. There shouldn't be so many Japanese around. What kind of group is this?

日本人の集団に遭遇したんですが、降りた駅でそのまま降りて、後ろから来てました。何のグループなんでしょうか？
