Japan's only cigarette making company is facing its first challenge from five smokers who sued the company recently for trying to make them addicted to a harmful product. The company, Japan Tobacco Inc, holds 80 per cent of the nation's cigarette market. Cigarette makers in Japan have an easier time compared to their counterparts in other countries. They can sell cigerettes in vending machines, advertise on late-night television and market them with only a wild warning on packages. The petitioners want the company to stop making cigarettes or at least carry a stricter warning.
