Seasonal Sleep 

84 soundscapes where seasons meet weekdays.
A new sleep BGM tuned to the season and day of the week.

Rooted in Japanese Five Elements and 24 solar terms,
each track guides you into deep, restful sleep.

84 patterns · 8 hours · 

Every video is structured around your natural sleep cycle — 8 hours, 7 phases:
・Phase 1 (10 min)  – Sleep Onset
・Phase 2 (20 min)  – Deepening
・Cycles 1–5 (90 min each) – Deep Sleep through Pre-Dawn

Brightness and BPM shift gradually with each phase, guiding your body from wakefulness into deep rest and gently back toward morning.
