As part of the plans for the exploitation of China; during the thirties and forties the subsidiary tobacco industry of the Mitsui Company started production of special 'Golden Bat' cigarettes using the then popular in the Far East trademark. Their circulation was prohibited in Japan and was used only for export.

Local Japanese secret service under the controversial General Kenji Doihara had the control of their distribution in China and Manchuria where the production exported. In their mouthpiece there were hidden small doses of opium or heroin and by this millions of unsuspecting consumers were addicted to these narcotics; while creating huge profits.

The mastermind of the plan; the General of the Imperial Japanese Army Kenji Doihara was later prosecuted and convicted for war crimes before the International Military Tribunal for the Far East; before being sentenced to death. Yet no actions ever took place against the company which profited from their production. According to testimony presented at the Tokyo War Crimes trials in 1948; the revenue from the narcotization policy in China; including Manchukuo; was estimated at twenty to thirty million yen per year; while another authority states that the annual revenue was estimated by the Japanese military at 300 million dollars a year.
