Authorities in Japan have been raiding "host bars" since the start of the year. These are clubs whose male employees trick women into spending large sums of money to drink and spend time in their company. Victims, who believe they're in love with their host, are left with massive debts, forcing some to turn to prostitution to pay them off. Authorities have already visited around 700 clubs and ordered some of them to close. Our correspondents report from Tokyo.
