Choir Nukku is a mixed-voice choir founded in June 2013 by university students in the Tokyo metropolitan area, with the motto "Singing with comfort". The name "Nukku" means "comfortable hiding place". The joyful members of Nukku bring together their ideas and aim to realize attractive choral expression through soft sounds and precise harmonies based on genuine tuning. The choir actively performs in solo concerts and at the Tokyo Chorus Competition, as well as on concert tours and invitational performances throughout Japan.
In 2016, they participated in the Tokyo Spring Chorus Contest (also known as "Harukon."), and won the third prize in the Folklore category (mixed voice).
In 2017, they won the excellent prize at the 10th Fukushima Vocal Ensemble Contest, and performed in the Alti Vocal Ensemble Festival "The Color of Song" .
