Something is causing groups of people to mysteriously age, and each of the victims used a rejuvination cream labelled "Beauty B Beauty." To try to bring the situation under control, Kitaro and the others head to the island where the youkai Nuppeppou is manufacturing the cream. But as soon as they land, they hear a strange song and their bodies begin to age. As they stand there bewildered, the Sand-throwing Hag starts behaving strangely. Though she pretends to know nothing, a jar of "Beauty B Beauty" cream falls out of her sleeve! What is Nuppeppou trying to accomplish? And what will happen to the Sand-throwing Hag...?!
I was tying my loincloth
in a bathhouse dressing room,
،كنت أربط مئزري في غرقة تبديل حمام عمومي
Im Badehaus wollte ich
meinen Lendenschurz binden,
Una vez, en el vestidor de los 
baños me puse el fundoshi
Una vez, en el vestuario de unos baños
me puse el fundoshi
Dans les vestiaires des bains,
je rattachais mon pagne…
Mi stavo annodando il fundoshi
 nello spogliatoio di una stazione termale
Eu estava amarrando minha sunga
no vestiário de uma casa de banho
Я завязывал набедренную 
повязку в раздевалке бани.
