Oyasumi Shuffle

Racing thoughts keeping you up? Just listen — let your mind gently unwind and drift into sleep. 5,000+ Japanese words and soothing BGM, no effort required.

You're in bed, but your mind won't stop — replaying today, worrying about tomorrow. The harder you try to sleep, the more awake you feel. Sound familiar?

Oyasumi Shuffle is a sleep support app that helps you drift off — just by listening.

HOW RANDOM WORDS QUIET A RACING MIND At night, one thought leads to the next, and the next — and suddenly you can't stop thinking. Listening to random, unrelated words gently breaks that chain, so your mind can finally rest. You don't have to "clear your mind" — just let the words wash over you.

This technique — the Cognitive Shuffle — was created by cognitive scientist Dr. Luc Beaudoin and has been featured by CNN and Forbes.

HOW IT WORKS

1. Pick a category
2. Press play
3. Put your phone down and close your eyes

That's it.

5,000+ JAPANESE WORDS ACROSS 20 CATEGORIES Choose a category to match your mood:

Flowers / Nature / Ocean / Space / Weather Animals / Food School Memories / Childhood Games / Festivals / Seasonal Events / Folktales Hot Springs / Gardens / Camping & Outdoors Music & Art / Sports / Travel / History & Culture / Vehicles

Fall asleep to the names of flowers one night, drift off into folktales the next — picking a different category each night becomes a small bedtime ritual.

SOOTHING BGM 17 BGM tracks across 4 genres: Ambient, Melodic, Piano, and Strings. Together with the word narration, they create a gentle soundscape for sleep.
