one of the jap women i know that she was working under a female boss for ml in jap. also i read her boss profile on internet who is the first female senior staff in foreign banks in jap.
while my friend's personal experience is tough. what i can say is finally she left jap and found a job in turkey.
i have to say jap women are smart at how to be aka act as a woman. its all up to your moral definition.
