Japan is set to impose stricter limits on mobile batteries carried by air travelers, joining a growing global push to curb fire hazards linked to lithium-ion powered devices.
Beginning April 24, new regulations from Japan’s transport ministry will align with updated international aviation safety standards, reflecting heightened concern over a rise in mid air battery incidents.
Airlines worldwide have reported cases of power banks overheating, emitting smoke, or catching fire, prompting regulators to act more decisively.
Under the revised rules, passengers may bring no more than two mobile batteries on board, each capped at 160 watt hours. The use of these batteries during flights will also be restricted. Charging power banks or using them to charge other devices will no longer be allowed while airborne.
Authorities are also urging passengers to keep batteries within easy reach rather than stowing them in overhead compartments, where delayed detection could worsen safety risks.
The long standing ban on placing such items in checked baggage remains firmly in place.
The measures highlight the aviation sector’s growing focus on lithium ion safety as portable electronics become essential travel companions.
Travelers are advised to take extra precautions, including insulating battery terminals, using protective cases, and avoiding contact with metal objects that could trigger short circuits.
For airlines and regulators alike, the message is clear. As passenger reliance on portable power grows, vigilance in managing the risks must keep pace.
