Never Ending World

This song, “Never Ending World,” was written in response to the Great East Japan Earthquake and is included on the triple A-side single “INORI,” released in 2011.

Its sorrowful piano melody and powerful lyrics about endings and beginnings leave a strong impression.

Although the song has a somewhat dark atmosphere, its immersive world makes it one I hope you’ll try singing at karaoke.

The melody has little range and is easy to sing, though it may feel a bit high for male singers.

SEKAI NO OWARI Mermaid Rhapsody

A popular group, SEKAI NO OWARI, delivers a sparkling song that evokes the summer sea and the freshness of budding love—perfect for listening to in summer.

This track is also the theme song for the film Princess Jellyfish.

In the fairy tale, the mermaid falls in love with a prince, but because she isn’t human, she can’t love like an ordinary girl.

While the fairy tale is a sad story, the mermaid in this song thinks that even if she can’t go to meet the one she loves, it’s not so bad to stay where she is, because that special someone will come to her.

It’s such an adorable song, isn’t it?

The End of the World/Fantasy

Released in November 2010 alongside “Angels and Demons” as SEKAI NO OWARI’s second indie single, “Fantasy” is said to be a song that vocalist Fukase wrote when he was a first-year high school student.

With its cheerful, upbeat feel, the song is notable for having a relatively narrow melodic range, making it one of the easier SEKAI NO OWARI tracks to try singing.

The lyrics, perfect for cheering someone on or giving yourself courage, are also a highlight!
