Do you know "Omotesandou Hills" which is a shopping mall on fashion?

Do you know "Omotesandou Hills" and "Roppongi Hills"? "Roppongi Hills" is famous in Japan. This has many stores , big screens and apartment house. Mr. Horie who was livedoor 's boss lived there. "Omotesandou Hills" was opened in February 2006. When I went to "Omotesandou Hills" , there were many people. I didn't buy anything. Because the items sold in "Omotesandou Hills" is very expensive. I think the people who live in Japan are very rich. But they make a mistake. Because they buy same things to other people.
