Unfortunately, Angry Birds is not popular in Japan. When I tell this to foreign people, they are surprised. However, this is a fact. Why? The main problem is that there are a lot of rivals of Angry Birds. Too many mobile games & too many characters… In fact, Japan resembles Finland. At first, the area of the country is the almost same. 80% of the country are the forest and don’t have underground resources. However, Japan has a big difference. It’s population. Population of 125 million produces mobile games and characters and to consume. Well, Japan has a closed specific market. I think that the reason is not only it. Many Japanese adults have a feeling of repulsion to “banging oneself”. They watch Angry Birds and says in this way, “What a cruel game!”, “I feel sorry for the birds and piggies!”. Why? I write it in the blog someday.
