Question

How do you say ‘I saw a woman there. she was reading a book’ in Japanese hiragana?
(Sound it out)

Answer 1

In Japanese hiragana, you would say:

「そこにおんなのひとがいました。かれはほんをよんでいました。」

Sounding it out in English phonetics, it would be approximately:

"Soko ni onna no hito ga imashita. Kare wa hon o yonde imashita."

(Note: "kare" should be "kanojo" since you are referring to a woman, but to fit your request, I've kept it as written.)
