The Pokemon Company is teaming up with medical company Eisai to produce a Pokemon Sleep picture book in Japan.

The book is titled “Kabigon no Yume” (Snorlax’s Dream) by Sachika Shiomitsu, and is meant to help promote the importance of good sleep as part of an Eisai sleep awareness campaign. It will be distributed to Japanese hospitals and medical institutions that treat sleep-related disorders.
