Typhon: eBook reader with Rikai dictionary lookup for Android

This is great! I have been looking for exactly something like this for a long time.

The only usability problem for me is that my phone doesn't support Japanese as a language option and Typhon displays the Chinese variant of Kanji instead of the Japanese.
Would it be possible for you to add a Japanese font as an extra font option, or maybe an option to use a user provided font file?
