Psychology studies show Japan is not doing enough to combat smoking

Tuesday, February 18, 2020

Japan’s policies to reduce tobacco use are not working well and must be strengthened for improved public health, according to two new studies led by researchers in the Department of Psychology.

Japan is the ninth largest cigarette market in the world, where smoking kills more than 150,000 people a year.

“Although Japan has taken recent steps to strengthen its anti-smoking laws, including stronger smoke-free policies that will be in place before the 2020 Olympics in Tokyo, our studies show the measures fall short of WHO recommendations,” said Geoffrey Fong, a professor of social psychology and public health, and the Chief Principal Investigator of the Waterloo-based International Tobacco Control Policy Evaluation Project (ITC Project).

The two studies from the ITC Project involved a survey of 3,800 smokers in Japan. The Waterloo researchers collaborated with researchers in Japan on both studies, which are the first national-level evaluations of Japan’s efforts to reduce smoking.

The first study, led by Janet Chung-Hall of the ITC project, found that only 30 per cent of Japanese smokers noticed text-only health warnings on cigarette packaging and only 14 per cent read them closely. The effectiveness of text-only warnings in Japan is much lower than in countries that require large pictorial warnings, now numbering over 100.

More than half of the Japanese smokers agreed that picture warnings would be more effective.

The second study, led by Genevieve Sansone of ITC, found that the partial smoke-free laws in Japan have led to higher exposure rates to second-hand smoke in workplaces, restaurants, and bars than in countries where more substantial bans have been implemented.

“The Japanese government has been very slow to develop and implement proven FCTC policies,” said Yumiko Mochizuki, a researcher at the Japan Cancer Society and ITC member. “These two studies show that Japan must do much more to combat smoking, the number one preventable cause of death in our country, which kills 160,000 smokers a year and over 15,000 non-smokers from second-hand smoke.”

The two studies were published in a special issue of the International Journal of Environmental Research and Public Health
