Hi, does any know where I can find the text for まんが日本昔ばなし　「かぐや姫」 or else the audio for the version by ふなさき　よしひこ?

Cheers.

I looked around for such text and didn't find anything. This is a really good find though, this video and the other ones. Thanks for sharing the link

If you mean for free, then I don't know, but the books of まんが日本昔ばなし stories with the same text as the narration are easily available in Japanese bookstores. There's a bilingual one too, including 「かぐや姫」, English title "Once Upon a Time in Japan."

Thanks!
