that does not tell anything - are they employees in a different country ?
Convenience store workers in the US earn about 20K USD per year - that is double the salary what a comp sci fresher from a tier 2 college (non-IIT) would earn in India. And that's a reasonable salary - at 10K USD per year, you can eat out everyday at pizza hut ("regular" food is cheaper), drink a couple of times a week and share a 3 bedroom apartment.
The "deviant-art-like-but-good" bit is probably referring to pixiv, a popular Japanese art site.
You're not going to live anywhere near a comfortable life in Tokyo on 2 million JPY a year, much less 1 million JPY a year. Convenience store workers here make around 950 yen/hr depending on what shift you're working on.
Assuming you find somewhere super cheap and livable (we're talking slightly larger than a single bed, maybe not even including a bathroom) for 50000 yen/mo, that's already 600,000 yen/yr on housing alone. You can see that there's not much left over for utilities, food, transportation, clothes, medical, etc... and we're not even talking taxes and luxuries.

Pretty sure Japan is more like USA in cost of living than India.
