This technique forces the user to fall asleep. However, since the user is left vulnerable, the enemy can wake the user up using a direct blow; the difficulty on how to wake the user up is dependent on how long they have fallen asleep.
Only Gaara has shown to know this technique, which he only used if he wished to release Shukaku's full power.
- This technique also translates to something akin to "Tanuki Sleep Technique", which is significant as Shukaku is a tanuki.
- In Naruto: Ultimate Ninja Storm, Naruto uses a similar technique while in a pyjama costume, he falls asleep while his health bar is recovering.
- It is currently unknown if former jinchūriki of Shukaku are able to use this technique.
