It is quite easy to be a Japnese amateur~ But won't the ignorance of Japnese kiss your ass when you want to deeply investigate the content of the game?
^o^~ It should be "kick your ass" or "come back to bite you in the ass". :D
And well, depending on the game (especially those with tons of kanji and lots of decision making), it can eventually become a problem.
I'm Japanese illiterate but almost half my gaming collection consists of games in Japanese. :P The only one that's given me a problem was Growlanser though. The rest I more or less know what to do and where to go or I'm using a guidebook/walkthrough. :P
The most fun though is when you absolutely, 100% DO NOT understand the language! :D
