Lithium battery safety measures in flights took effect across Japan on Tuesday. Airlines now require passengers to keep portable chargers within easy reach during travel. This decision follows multiple incidents of lithium-ion battery fires onboard, prompting urgent action.
At Tokyo’s Haneda Airport, All Nippon Airways (ANA) staff actively reminded travelers not to store power banks in overhead bins. “For safety, please keep them nearby,” announced a crew member at the gate. Other airlines quickly adopted similar measures nationwide after the transport ministry’s advisory.
Therefore, the Ministry of Land, Infrastructure, Transport and Tourism highlighted the dangers of damaged or aging lithium-ion batteries. These devices can overheat or ignite if crushed, especially in confined spaces. While power banks were already banned from checked luggage, the new rules tighten in-cabin storage.
Moreover, aviation safety experts suggest these lithium battery safety measures in flights may only be the start. “Passengers carry more high-capacity electronics than ever,” said Dr. Kenji Sato, an aerospace safety researcher. “Airlines worldwide must rethink how they handle devices like power banks and e-cigarettes.”
The International Air Transport Association (IATA) is reportedly updating global guidelines. New standardized protocols for battery-powered devices could emerge by early 2026. Meanwhile, Japanese airlines are training crews on emergency responses, including using specialized fire containment bags.
Recent thermal events pushed Japan to act faster. In May 2025, a power bank fire forced an emergency landing in Osaka. Another incident in April delayed a Fukuoka-bound flight. These cases reinforced the need for stricter lithium battery safety measures in flights.
Travelers had divided opinions on the new policy. “It’s a hassle, but safety matters most,” said frequent flyer Rina Kobayashi. Others raised concerns about enforcement. “Will flight attendants check every bag?” asked American tourist Mark Gibson.
Airlines now display warnings at check-in counters and boarding gates. The transport ministry will introduce multilingual advisories for international travelers by August. As lithium-ion devices become more common, Japan’s proactive approach may set a global precedent. For now, passengers must adapt to these crucial safety changes.
