Moumoon (stylized as moumoon) is a group formed by YUKA (Vo./ Lyrics) and Masaki (Gt./Composer) 『moumoon』 is a made-up term with a French word "mou (soft)" and "moon": soft moon.
They met at a summer rock festival about 10 years ago. A few weeks later, YUKA was struck by Masaki’s demos and she decided to start working with him. Masaki also felt something special with YUKA’s vocal so they started to make demos together. Thus moumoon was formed.
They have self-produced and arranged almost all of their songs.
They both grow up with classical music with Masaki playing piano and YUKA playing violin. Their present musical style covers various types of music such as pop, alternative rock, electronica, folk and indie rock. However, YUKA’s lyrics and vocal add scenery and a story line to Masaki’s sensitive but dynamic melodies, thereby painting every song the “moumoon color” which is like phases of the moon.
After moumoon was formed, their songs were power played on radio and used in many TV commercials earning them name recognition. In 2014, they held the biggest tour of their career (16 cities in Japan) and performed at various music festivals. They are expanding their activities and have built a unique position as the first Japanese artist who has gained acceptance overseas.
They are holding unique live shows called “FULLMOON LIVE” every full moon night.
