The Door of Memories is the fifty-first episode of the Natsume Yuujinchou anime. It first aired on March 19, 2012. It is the twelfth episode for Natsume Yuujinchou Shi, which is the fourth season of the anime.


Natsume, accompanied by Nyanko-sensei without his consent, set out to visit his old home. He visits a relative to pick up the key to the house, but is being followed by a youkai who wants him to draw a mouth for it.

While staying at the relative's house for some tea, the youkai once attempts to emotionally take over Natsume but is stopped by Nyanko-sensei. Natsume leaves and leads the youkai away from the home and Nyanko-sensei scares it away from the house vicinity completely.

After the two attempts to get back on track to finding Natusme's house, Natsume is suddenly attacked by the same youkai and becomes lost in old memories.
