Japanese Folk Tale

104 The Yanagita Guide to the Japanese Folk Tale
The mother was a she-demon. The child escaped by the help of a
charm he received from a priest. MK I 7 41, "The priest and his
novice" (Oshe to koze). A great snake 33 fathoms long came to
have its head cut off. The priest destroyed the snake with three
charms. It was a musk snake, a treasure bestowed by the Sun.
Further reference:
There is an example in northern Africa of spittle answering in
place of a man.

101. The Privy at the Demon's House
This is the story about the three charms with the charms omitted.
It is close to "0 Sun, the chain."
Gifu, Yoshiki-gun, Kamitakara-mura: Hidabito V 5 21, "The three
charms" (Sanmai no ofuda). Two tales. In the first, the brothers
stopped at the hut of an old woman and escape through the window
of the privy. They tied the rope to the post and prayed fervently
as they left. It answered for them. There seems to be
interest in this point, but there are many regions which have
stories of the Privy Deity's acting as substitute. The second tale is
like the last part of the stepchild gathering chestnuts. The stepchild
tied the rope to a broom and went home. The child herself
answered, "Not yet."
102. Eating a Demon in One Bite
This is the latter part of "The three charms." A demon who is
deceived by a priest is always destroyed by agreeing to compare
tricks.
Iwate, Isawa-gun: Kogane 55, "The she-demon who turned into a bean
and was eaten" (Marne ni natte kuwareta onibaba no hanashi).
Kamihei-gun: Tono 276 No. 165. No title. A man called Nue at
Hataya went into the mountains. He matched wits as the priest did
with a blue ghost. He made it small and put it into a tinder box.
When he got home and opened the box, a blue spider came out.
Tochigi, Haga-gun: Dai-ni 38, "The yamajii who turned into a flea"
(Nomi ni natta yamajii no hanashi). Shimotsuke 51, "The yamajii
who turned into a flea" (Nomi ni natta yamajii no hanashi). The
demon turned into a flea and the priest crushed him.
Niigata, Minamikanbara-gun: (no source). A lazy man who deceived a
demon by persuading it to turn into a small piece of mochi ate it.
