Japan Tobacco (JT) plans to launch Ploom Tech in cities across Japan next year to challenge Philip Morris International’s iQOS heat-not-burn product, Reuters reported.

JT encountered supply problems following the test launch of Ploom in Fukuoka in March, however the cigarette maker will have increased production capacity by 10 times next year, the news agency said. When the roll out will begin next year has not been set, Reuters said.
