祖母は日本が懐かしい。亡きに成る前に千葉に返りたい 。
My grandmother misses Japan and wants to return to Chiba before she dies.

please tell me- did that make any sense? is it ok to use 返る instead of 帰る? thanks in advance!

i pass- 章気 (shouki) miasma

返る meaning return, but not in the way that you wanted to use it in that sentence (correct me if im wrong)
from what i understand, 返る is used as 'return' in cases such as "i returned to books to 82riceballs", "please return those tools", "he returned my pen" etc
imo, for that sentence, if she came from Chiba to begin with, you could use 帰る, you could also use 戻る(modoru), which also means return
i know that 戻る can be used to "i want to return to that time/place" but im not sure about returning objects

ummmm im not gonna do this word because i have no idea LOL

so ill just pass it onto the next person
章気 (shouki) miasma

章気ってどう言う意味でしょう。。。
shouki tte dou iu imi deshou...

That's my contribution and I really mean it too^_^;;

I pass on 時々(tokidoki)

oops!!! my mistake- i typed "shouki" wrong. it should be 瘴気. that's probably why no one got it... ごめんね〜 *deeeeeeply sorry*

anyways,
