Anime Songs By K-Pop Groups

If you go on YouTube or TikTok it’s easy to find users who have edited anime openings to sync with K-pop songs. This isn’t news, but actual K-pop groups being asked to sing songs for anime OSTs is.

Recently, there has been an influx of K-pop groups being recruited by anime studios to take part in OSTs. While it’s been gaining traction as of late through shows like Tower of God, World Trigger, and Black Clover, it’s not a new trend. Some of the earliest records of this happening date back to the early 2000’s.

Tohoshinki/Dong Bang Shin Ki is a duo, previously a 5-member group, that has been active since 2003. During their almost 20 years in the industry, the group has become known as K-pop royalty as they’ve toured all over the world and have a massive following in Japan as well as the rest of the world.
