Working Lives Tokyo: Hostess

As a hostess at a club in Shinjuku Kabuki-cho, Emiri Aizawa, 27, pours drinks, lights cigarettes and listens to men.
"My main job is let them have fun," she says.
"Of course, there have been customers who asked for more, because we are men and women, but I politely say, 'No.'
"I don't think you can do this job for a long time if you do more [by sleeping with clients]."
In one night, on her 23rd birthday, she brought in 27 million yen ($245,000; £150,000) for the club, of which she received a sizeable chunk.
And as a model with her own fashion line, she earns more than $1m a year.
"My modelling career and the clothing brand only happened because I did well at the club," she says.
"Because I am a hostess, I have faced a lot of discrimination.
"People said that I wouldn't achieve anything, but that made me more determined.
"So I don't think there is anything that women cannot achieve."
