Japan is the world’s biggest heated-tobacco market. IQOS and the rest of the “heat-not-burn” lineup just outsold regular cigarettes for the first time this year. You can buy those at a convenience store. What you still cannot buy, legally, is a nicotine vape.
That is not because nicotine is banned. It is because Japan treats nicotine that does not come from a tobacco leaf as a drug.
Cigarettes and heated tobacco contain leaf, so they sit under the Tobacco Business Act and the Ministry of Finance — the same ministry that likes the tax revenue. Nicotine liquid with no leaf falls under the Pharmaceuticals and Medical Devices Act and the health ministry. To sell it, a company would need two approvals: the liquid as a medicine, and the device as a medical device. Nobody has gotten that approval. The last time the government even said it would “look at” the rules was 2014. Twelve years later, same wall.
Nicotine-free vapes are just consumer products. That is why Japan has vape shops that cannot sell the one thing most vapers actually want.
You can import nicotine liquid for yourself. Customs will let through a one-month supply — 120 milliliters — without extra paperwork. More than that needs a pharmaceutical import certificate. Give it to a friend or sell it and you have broken the law, money or no money.
So the country ends up in this weird spot: personal use is fine, a legal domestic market is not. Adult smoking is still 15.7 percent (25.6 percent of men). About 40 percent of those smokers have already switched to heated tobacco. Health surveys even undercount it, because a lot of people who only use IQOS will say they “don’t smoke.”
Britain went the other way and regulated vapes as consumer products. That created a huge legal market — and then a disposable-vape mess, youth-use panic, and a public that now thinks vaping is as bad as smoking. Japan avoided that circus by never letting the market exist.
Could a company force a rule change the way LUUP did with e-scooters? Not really. You cannot run a “trial” that consists of selling an unapproved drug. And there is no big Japanese vape company with years of cash and a reason to fight. Anyone who wants nicotine just orders it from overseas.
The pharmaceutical system also wants a medical purpose. “This is for fun” is not an indication. Smoking cessation would be the obvious claim, but a health-ministry committee already said e-cigarettes have not been shown to work for quitting — and flagged formaldehyde and other junk that can spike depending on the brand and the batch.
So Japan keeps the legal nicotine that looks like a cigarette, taxes it, and leaves the vape bottle in a customs gray zone. Convenient if you like heated tobacco. Extremely annoying if you just want a legal pod.
