A bipartisan group of lawmakers requested that Japan's Ministry of Health, Labour and Welfare implement a total smoking ban across the National Diet and other government facilities [1].

The move signals a push to close regulatory loopholes that currently distinguish heated tobacco products from traditional cigarettes. By targeting administrative grounds, the group aims to set a national standard for public health, and protect vulnerable populations from secondhand smoke [1].

Senator Matsuzawa and the bipartisan parliamentary group focused on promoting second-hand smoke prevention measures during their visit to the ministry on July 8 [1]. The group said the government should strengthen regulations on heated tobacco products to make them equivalent to those for combustible cigarettes [1].

This request follows the full implementation of the revised Health Promotion Act in April 2020 [2]. While that law established broader restrictions on smoking in public spaces, the lawmakers said that current rules are insufficient to prevent health damage from passive smoking [1].

Senator Matsuzawa said the system needs a review to create a framework that saves the vulnerable [1]. The group said that government facilities, including the Diet, should lead by example by becoming entirely smoke-free environments [1].

The request emphasizes the need to prioritize public health over the convenience of smokers within state-operated buildings. The lawmakers said that the health risks associated with secondhand smoke necessitate a more aggressive approach to regulation than what is currently provided under the 2020 guidelines [1], [2].

The group said the government should strengthen regulations on heated tobacco products to make them equivalent to those for combustible cigarettes.

This effort reflects a growing legislative push in Japan to treat heated tobacco products as equal to traditional cigarettes in terms of health risks and regulation. If the Ministry of Health adopts these requests, it could trigger a wider shift in Japanese public space policy, moving from 'designated smoking areas' toward total prohibition in government-managed sectors.
