BACKGROUND AND AIMS: In addition to some electronic cigarettes (e-cigarettes), new heat-not-burn @entity286 products Ploom and iQOS have recently begun to be sold by @entity286 companies. These products are regulated differently in Japan, depending on whether the contents are liquid or @entity286 leaf. Our objective was to estimate percentages of awareness and use of e-cigarettes and heat-not-burn @entity286 products among the Japanese population, including minors. DESIGN AND SETTING: An internet survey (randomly sampled research agency panellists) with a propensity score adjustment for "being a respondent in an internet survey" using a nationally representative sample in Japan. @entity1 : A total of 8240 respondents aged 15-69  years in 2015 (4084 @entity1 and 4156 @entity1 ). MEASUREMENTS: Adjusted percentages of awareness and use of e-cigarettes ( @entity1239 or non- @entity1239 e-cigarettes) and heat-not-burn products among total @entity1 ; product types and percentages ever used among e-cigarettes ever users. FINDINGS: Of respondents in Japan, 48% [95% confidence interval (CI)  =  47-49] were aware of e-cigarettes and heat-not-burn @entity286 products, 6.6% (95% CI  =  6.1-7.1) had ever used, 1.3% (95% CI  =  1.0-1.5) had used in the last 30  days and 1.3% (95% CI  =  1.1-1.6) had experience of >  50 sessions. Seventy-two per cent (95% CI  =  69-76) of ever users used non- @entity1239 e-cigarettes, while 33% (95% CI  =  30-37) of them used @entity1239 e-cigarettes, which has the majority share world-wide; 7.8% (95% CI  =  5.5-10.0) and 8.4% (95% CI  =  6.1-10.7) of them used the new devices, Ploom and iQOS, respectively, with a relatively higher percentage among the younger population. CONCLUSIONS: Approximately half the respondents in a Japanese internet survey were aware of e-cigarettes and heat-not-burn @entity286 products, 6.6% had ever used. More than 70% of ever users used non- @entity1239 e-cigarettes, the sale of which is not legally prohibited, even to minors, in Japan, and 33% of them used @entity1239 e-cigarettes; 3.5% of never smoking @entity1 and 1.3% of never smoking @entity1 had ever used e-cigarettes. Corresponding figures for use in the last 30  days were 0.6% and 0.3%, predominantly non- @entity1239 e-cigarettes.
