Edo Lullaby (江戸子守唄・Edoko moriuta) is a traditional Japanese cradle song. It originated in Edo, was propagated to other areas, and is said to be the roots of the Japanese lullabies. In Yumeutsushi-hen, the fourth episode of Higurashi no Naku Koro ni Kira, Hanyū is heard singing a regional variation of this song to a younger Rika. The lyrics are said to point to the location of a mysterious hidden shrine.

ねんねんころりよ　おころりよ. ぼうやはよい子だ　ねんねしな. nen, nen korori yô okorori yo. bōya wa yoi koda, nenneshina~ Hushabye, Hushabye! Be good my dearest one, please sleep!
ぼうやのお守りは　どこへ行った. あの山こえて　里へ行った. bōya no omori wa, doko e itta? ano yama koete, sato e itta. Where did my boy's babysitter go? Beyond that mountain, back to her home.
里のみやげに　何もろうた. でんでん太鼓に　笙の笛. sato no miyage ni, nani morōta? denden taiko ni, shō no fue. As a souvenir from her home, what did you get? A toy drum and a shō flute.
