You could hand out flyers... LOL.
Seriously, theres **minimal** IT work around Osaka, but generally it's nothing more than a month or 2 month stints then onto the next job (provided there is one). In fact, if you can't speak/read fluent Japanese, you're pretty much screwed from the start. Theres one American dude here doing all the IT work for our English School and we've employed him for the last 3 months part-time... he can't really speak or read Japanese... but then again, we don't NEED him to. It'd be way different in any other workplace.
Eeeerm, modelling work? (no joke)... or being an extra for short film or TV commercials?
Like Andrew akeenan said, you can work anywhere if your Japanese skill is good enough, but that opens up the 'damned if you do' element where you're treated eeeerm... 'like a foreigner'... because you're not Japanese. No acceptance is bad in the workplace in a Japanese company just ask Evo_Lee
