The natural soundscapes collected around the world by sound environment designer Takashi Kokubo contain abundant 1/f fluctuations—the gentle micro-variations found in waves, wind, and other elements of nature known to promote comfort and physiological calm. These “soothing night soundscapes” work at an instinctive level, helping the body settle into restful sleep.

For those who struggle to fall asleep due to stress or anxiety, or who wake feeling unrefreshed, this album offers a drug-free first step toward re-training the body for natural, restorative sleep.
