According to [the _Hunter x Hunter_
Wiki](http://hunterxhunter.wikia.com/wiki/Feitan):

> Feitan's first language is Chinese; he speaks in sentence fragments in
> Japanese while switching to his native tongue when angered.

Given this, and the text is written in either Japanese kanji or Chinese (as
[@kuwaly](https://anime.stackexchange.com/users/93/kuwaly) beat me to pointing
out), and the fact that there is a Japanese translation provided, I'm going to
conclude that the text is written in Chinese. (There may be some fragments of
Japanese, but I somewhat doubt that.)
