Labels — Sleep Loops

'Sleep Loops' is a small label from Sapporo, Hokkaido, Japan. Originally based on the regular recordings of nursery school teacher Yuri Hatsuka from 1993, the main focus was on 'sleep cycles'. Her weekly recordings were used as an educational tool in kindergartens and schools for almost twenty years. 'Sleep Loops' was founded in 2011 to cover her many albums as well as those of friends.
