July 2026: Japan Backs Off From Tighter Restrictions on Heated Tobacco Products
Japan’s health ministry has decided to defer implementing stricter regulations on heated tobacco products (HTPs) for the time being. The decision comes as part of an ongoing review of the country’s secondhand smoke measures, originally enacted under the revised Health Promotion Act in 2020.
Rather than tightening restrictions on HTPs to match the strict bans imposed on traditional cigarettes, the ministry plans to maintain the current regulatory baseline while committing to ongoing research into the long-term health impacts of HTP emission exposure. Instead of a hard crackdown, the ministry is shifting its focus toward administrative oversight, proposing a new notification system that requires bars, restaurants, and other smoking-oriented businesses to officially register with local governments.
Under the existing 2020 law, smoking traditional cigarettes is strictly forbidden inside most hotels and dining establishments outside of designated, ventilation-controlled smoking rooms where eating and drinking are barred. In contrast, rules for HTPs have remained significantly more relaxed, allowing consumers to use the devices in designated areas where food and drinks can still be served – a regulatory distinction that remains intact under the new proposal.
The health ministry’s decision to pause further restrictions provides significant breathing room for major global tobacco players operating in the country. Japan stands as the largest heated tobacco market in the world, accounting for roughly a third of the entire global HTP sales volume.
Because traditional commercial e-cigarettes (vapes containing liquid nicotine) are effectively banned under Japan’s pharmaceutical laws, HTPs like Philip Morris International’s IQOS, British American Tobacco’s glo, and Japan Tobacco’s Ploom have become immensely popular alternatives. Today, HTPs make up nearly half of the total tobacco market in Japan, making the country a vital testing ground and profit driver for the global tobacco industry’s transition away from traditional combustible cigarettes.
An expert panel is expected to formally compile and finalize the secondhand smoke policy recommendations later this summer, though the ministry’s current trajectory signals a reprieve from any imminent regulatory disruption for HTP manufacturers and consumers alike.
