Yes, smoking is allowed at Niigata Airport (KIJ) in enclosed indoor smoking rooms. Like most Japanese airports, Niigata keeps the terminal smoke-free except for air-conditioned smoking cabins, so head for one of the designated rooms rather than looking for open-floor ashtrays. Best of all, two of the three rooms are airside, inside the boarding lounges, so you can smoke after security and still be near your gate.
Domestic Boarding Lounge (2F)
The 2nd-floor domestic boarding lounge has an enclosed smoking room inside the secure area. This is the most convenient option for travelers on domestic flights — clear the security checkpoint, then find the marked smoking room within the boarding lounge before you head to the gate.
International Boarding Lounge (3F)
International departures use the 3rd-floor boarding lounge, which also has an enclosed smoking room inside the secure area. After passport control and security, you can smoke airside while waiting for boarding.
International Arrivals Lobby (1F)
For arriving passengers, there is a smoking room on the 1st floor in the international arrivals lobby, beside the delivery (baggage forwarding) counter — handy for a cigarette right after you collect your bags and clear customs.

Heated-tobacco devices such as IQOS, glo and Ploom are treated like cigarettes in Japan, so use them inside the smoking rooms rather than in the open terminal. Flying onward along the Tohoku and Sea of Japan coast? See our guide to smoking at Sendai Airport (SDJ).
