Hiroshima, Japan
Smoking policy at Hiroshima, Hiroshima Airport (HIJ)
Warnings & Caveats
Smoking outside designated rooms anywhere in the terminal is prohibited under Japanese law and airport regulations. Heated tobacco (IQOS, glo) must also be used only inside smoking rooms. Vaping is subject to the same restrictions as cigarettes at most Japanese airports.
Hiroshima Airport follows the standard Japanese model: smoking is only permitted inside designated enclosed smoking rooms (喫煙室), and lighting up anywhere else in the terminal will get you in trouble. The airport's own floor map explicitly marks smoking areas on both the 1st floor (Arrival Lobby) and 2nd floor (Departure Lobby), so there are options both before and after security.
Before Security
The 1st floor Arrival Lobby has at least one marked smoking area, accessible to arriving passengers and anyone in the landside zone. The 2nd floor Departure Lobby also has a smoking area listed on the official floor map, which you can use before clearing security for your departure.
1F Arrival Lobby: Smoking area marked on the official floor map, usable by arriving passengers and meeters/greeters landside.
2F Departure Lobby: Smoking area on the departure level, accessible before you pass through security screening.
After Security
The official floor map lists smoking areas on the 2nd floor departure level, which in Japanese airport layouts typically includes both landside and airside sections. Based on the airport's own facility listing and the broader pattern confirmed for Hiroshima by third-party sources, enclosed smoking rooms are available airside as well. Exact gate-proximity details are not published in the scraped content, so check the airport's printed floor map or ask at the information desk (1F) once you arrive.
Vaping and Heated Tobacco
Japan treats heated tobacco products (IQOS, glo, Ploom) the same as cigarettes at most airports: use them only inside the designated smoking rooms. Vaping policy follows the same rule at the vast majority of Japanese airports. Do not assume an outdoor area or corridor is acceptable; the rooms are the only sanctioned spots.
Transit and Layovers
Hiroshima is a single-terminal airport handling both domestic and international flights on the same floors. If you are transiting between a domestic and an international flight, you will likely pass through the same building and can access the smoking rooms on the relevant floor without leaving the secure area, though re-clearing security may be required depending on your routing.
Bottom Line
Smoking rooms exist on both the landside and airside at Hiroshima Airport, so you are covered before and after security. Stick strictly to the marked rooms and you will have no issues.
