Sleepy Land — The Deepest Form of Groove-Based Deep Sleep
A new frontier in sleep-focused sound wellness

Sound wellness is becoming a global movement—from vibroacoustic therapy to sound baths, the market is projected to reach ¥86.8 billion by 2035. Within this expanding field, ONTSUBU LLC explores a unique direction: sleep healing through groove.
This project was featured at Mitsukoshi Isetan Nihombashi, one of Japan’s oldest and most prestigious luxury department stores, founded in 1673, as part of the sleep-themed exhibition “Sleeping World.”
