## What is Oyasumi Shuffle?

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.

ABOUT THE VOICE
Words are narrated in Japanese using AI voice synthesis. Some accent or pronunciation may differ slightly from natural speech.

CUSTOMIZE YOUR WAY
- Session duration: 5 to 120 minutes
- Word interval: 3 to 15 seconds
- Speech speed: 0.5x to 1.5x

GENTLE BY DESIGN
- Background playback — audio continues when you close the screen
- Dark theme — easy on your eyes in a dark room
- Large buttons — effortless to use when you're sleepy
- Accessibility — VoiceOver, Dynamic Type, and Reduce Motion
