Vibration Alarm Only (アラームはバイブのみ - Alarm)
The strict capsule etiquette prohibiting loud morning audio alarms inside sleeping pods. Guests must use silent smartphone vibration alarms kept close to their pillows, or special integrated lighting timers to wake up quietly.
Because sleeping pods amplify sound, a single shrill phone alarm will instantly shock dozens of neighboring guests awake. To preserve quiet harmony, hotels enforce silent morning awakenings as an absolute courtesy.
Set your alarm tone volume to zero, enabling only deep vibration mode. Slide your smartphone under your thin pillow so only your skull feels the morning vibration. Some modern pods feature built-in silent light-up dimming clocks.
