If you're a K-pop group or artist and you want to make it in Japan, one of the ways to do it is to sing a theme song for a popular anime series!
From One Piece to Inuyasha, here are 10 opening and closing theme songs that were performed by K-pop artists.

While CNBLUE had released singles in Japan previously, "In My Head" was the group's first major label debut in the country.
9. FT Island - Toriko: "Satisfaction"
FT Island have a big following in Japan, so seeing their songs come up in various anime series isn't too surprising.

Younha has been around for quite a while, but "Houki Boshi" was the song that propelled her into the spotlight!
7. MBLAQ - Beelzebub: "Baby U!"
As far as opening theme songs go, MBLAQ's "Baby U" is the perfect track for a show that's about a baby demon!

Secret absolutely nails the cutesy anime feel of this "Naruto" spin-off with "Twinkle Twinkle"!
