Amazake-babaa (甘酒婆, "amazake hag") is an old woman yōkai from the folklore of Miyagi and Aomori prefectures in Japan.
Amazake-babaa comes to the doors of houses at late night asking for amazake in a child like voice, but anyone who answers fall ill. It was said that to keep her away, a cedar leaf is placed in the doorway. She was also known as the god of Chickenpox.
