We can watch 5 commercial broadcasting. Each channels almost produces one drama in every night. So I think many dramas are made in Japan.
There are a lot of variations for contents, comedy, love story, mystery or family drama. Audience rating and theme songs for each drama is one of topics for people. As a trend of drama, young popular actors or actresses are lead parts. I watch three dramas in a week. One of member of popular super idol group, "ARASHI", Kazunari Ninomiya appears in a drama that I watch this season, "Ryusei no Kizuna". It becomes popular now. He appeared in Hollywood movie, Letters from Iwo Jima. The story is unique and very interesting. Theme song is "Beautiful days" that ARASHI sings. It will become hit song in near future. And I like a song "Orion" that are inserted in this drama.
Orion by Mika Nakashima
Mika Nakashima is very popular female singer and she appears in this drama as an actress.In addition, I attached my favorite and recent hit song of ARASHI, "Kaze no Mukoe."
Japanese dramas are popular in Asian counties now. To watch Japanese drama or movies might be most useful way for knowing our lifestyle.
