Akane entered the Japanese girls top 10 as 茜 (deep red) in 1993 at #8. This was its only entry in the top 10. It is currently (as of 2018) not in the top 100 anymore.

11 baby girls born in the USA (2015) were given Akane.
I have a friend named Akane whose kanjis are 朱峰 (red/vermillion peak). It is an irregular reading, and definitely a one-of-a-kind combination... I'm not sure what the parents mean by giving her that name, though :)
