In Japan, heated tobacco products (HTPs) are regulated as tobacco products and are allowed for sale, including through online channels. HTPs are widely available in specialised retail stores. The law allows manufacturers to make health-related claims about these products and does not impose restrictions on their flavours; however, it also requires health warnings on product packaging. Also, there are legal restrictions on the use of HTPs in public places.

Data show that there were an estimated 13.5 million current HTP users in Japan in 2023, representing a dramatic increase from 2015, when the number of current HTP users was estimated to be 220,000 individuals. In other words, the prevalence of current HTP use among adults increased from just 0.2% in 2015 to 12.4% in 2023.
