I'm thinking of what is the original music of Japan. Because pop music(probably not only pop music) is from Western. So Japanese pop music also is heavily influenced by Western style. Although I don't think Westerners own pop music, sometimes I'm afraid where is the original of Japan or Eastern.
That's why I was going to set up this thread. It tend to happen that pop music borrows Folkloric music though, there might be some interesting things.
This thread is for Shima Uta, Ryukyuan music, Ainu music, and so on as pop music.
Chitose Hajime is a Shima Uta singer from Amami. This her debut single called Wadatsumi No Ki is reggae taste pop music..Most japanese know this song.
Nowadays her voice is getting weak, but she stood out as a Shima Uta singer.
Kizuki Minami is the newest Shima Uta singer. She is 20 years old. This song is produced by Miho Hatori(ex.Cibo Matto).Miho Hatori is familiar with Ryukyuan Music.
The vibrato that is the feature of Shima Uta is few in her singing voice.
