Japan will start enforcing tighter in-flight rules for power banks on April 24, limiting passengers to two units and banning their use for charging onboard. (mlit.go.jp) Japan’s transport ministry said the new standard follows an International Civil Aviation Organization emergency revision aimed at reducing lithium-battery fire risk on aircraft. The ministry opened public comment on February 27, 2026, and said the new standard was expected to take effect in mid-April. (mlit.go.jp) Under the revised rule, each passenger may carry no more than two power banks, and each must be 160 watt-hours or less. Power banks remain banned from checked baggage, and airlines tell passengers to insulate terminals with tape or a plastic bag to prevent short circuits. (ana.co.jp) Japan Airlines said charging a power bank from a seat outlet or USB port will be prohibited from April 24, 2026. It also said using a power bank to charge another device during the flight will be prohibited. (jal.co.jp) The change follows a run of lithium-battery fire incidents on aircraft that regulators in Japan described as increasing worldwide. Japan’s ministry said the risk review also drew on International Civil Aviation Organization deliberations in late March. (mlit.go.jp) Japanese airlines are already warning passengers that the limit could tighten again. JAL said expected International Air Transport Association rule changes could cut the per-unit limit to 100 watt-hours from January 2027. (jal.co.jp) The battery rule change is landing as travelers also face disruption checks tied to recent earthquake activity. Narita Airport says it broadcasts emergency earthquake warnings in all three terminals when a quake of at least lower-5 on Japan’s seismic scale is forecast, and suspends other announcements during the alert. (narita-airport.jp) Japan’s Meteorological Agency is still publishing current earthquake information and tsunami potential updates, and the Japan National Tourism Organization is directing visitors to monitor transport news and weather advisories during their stay. (data.jma.go.jp, japan.travel) As of April 23, ANA’s international operations page showed no airports under a delay or cancellation advisory, but both ANA and JAL tell passengers to check live flight-status tools because operating conditions can change on the day of travel.
