Niko Kawagoe was already a sous chef at the Tokyo Marriott at 22 and would have likely become the head chef before long, which would probably make her a superstar in the culinary world...
until she decided that she would rather make money showing her asshole on camera. Somehow, she still managed to get an actual head chef job without telling anyone that she was doing porn, and managed to keep it even after the restaurant found out. I have no idea why. I'm not even saying this from a puritan perspective, but what restaurant would want a bunch of gooners showing up to try to get a glimpse of the head chef's tits?
On the other side of the JAV money spectrum are male actors, who barely make enough money to cover their train tickets. Gay for pay is largely a myth here, but in nipland every guy in the industry that's not a middle-aged ugly bastard is also getting fucked in the ass by trannies so they can afford their rent. Shimiken was probably the highest-paid guy in the industry and he still quit because podcasting paid better than being Japan's Best Dick for 2 decades.
