and the games on the jpn store are they in English or subtitles only?
Games that are developed in Japan are only in Japanese. No reason to be otherwise.
Games that are Western developed have a very high chance of having English as an option (or even just in English as standard). But this is not always the case.
However, I am not sure if this counts for digital content.
If you want English content, the JPN store is not the way to go I think.
