Now... I think in Kyoto that's a pretty decent number! Tech company salaries in Kansai are _so much worse_ than in Kanto when I looked (5 years ago but). But if you're in Tokyo and making that... honestly you are gonna be better off elsewhere.
I have seen worse numbers at other game companies, but hearing 500k+ per head in profit, it's kind of disgusting they don't pay a bit more.
