According to the version of the legend handed down in Ibaraki City itself, Ibaraki Doji was born in Mizuo village (today's Ibaraki City) after a sixteen-month pregnancy and a very difficult delivery; by birth, he had already acquired his teeth, and began to walk almost immediately thereafter, and looking on his mother's face, he smiled and gazed with such a piercing stare that his mother died of shock.
茨木市の伝承では、茨木童子は水尾村（現・茨木市）の生まれだが、16ヶ月の難産の末に生まれたときにはすでに歯が生え揃い、生まれてすぐに歩き出して、母の顔を見て鋭い目つきで笑ったため母はショックで亡くなった。
