Japan-based air carriers reported a record 429 in-flight smoking incidents in 2025, the highest level since data collection began in 2004 and a sharp rise from 65 cases in 2019, according to the Ministry of Land, Infrastructure, Transport and Tourism. Authorities believe the growing use of heated tobacco products — now accounting for over 40% of domestic tobacco sales, per the Tobacco Institute of Japan — has contributed to the increase, as vapor can trigger aircraft smoke detectors. Smoking on board, including use of e-cigarettes and heated products, is prohibited under Japan’s Civil Aeronautics Act, with violators facing fines of up to ¥500,000 ($3,150) if they fail to comply with crew instructions.
