It’s a great free to play online game from an NHK TV show called Bitworld (there’s no connection to Bitcoin - I just like it).
A lot of people in tech are interested in Japanese and even speak it, but you can play without knowing the language.

Play the Ruin game free online (needs Flash though). You don't need to read Japanese but I can give hints if you reply in comments.
I think it's so great - really Japanese Showa-era (pre/post WW II) atmosphere - makes you jump!
And clever puzzles too!
