Japan will tighten its in-cabin power-bank rules on Friday, April 24, capping passengers at two units and banning charging during flight. (mlit.go.jp) Japan’s transport ministry said the new rule applies to power banks of 160 watt-hours or less, which remain carry-on only, while anything above that limit is not allowed. The ministry announced the change on April 14 after an emergency revision to international safety standards was approved on March 27 by the International Civil Aviation Organization. (mlit.go.jp) The added restrictions are specific: passengers may not charge a power bank from the aircraft’s power supply, and they may not use a power bank to charge another device in the cabin. Japan Airlines posted the same April 24 effective date on its baggage pages for domestic and international flights. (mlit.go.jp) (jal.co.jp) The change rewrites a familiar routine for travelers who use battery packs to top up phones, tablets, or handheld game systems in the air. It also hardens a rule that already kept power banks out of checked baggage because lithium-ion cells can overheat, smoke, or catch fire if damaged or short-circuited. (mlit.go.jp) Japan’s ministry tied the new limits to a rise in lithium-battery fires on aircraft worldwide. In a separate July 2025 notice, it told passengers on Japanese airlines not to place power banks in overhead bins and to keep them where crew or travelers can see them. (mlit.go.jp 1) (mlit.go.jp 2) Airlines are already telling passengers to check carrier-specific baggage rules, especially on code-share itineraries where another airline’s policy can control. All Nippon Airways says different rules may apply when another carrier operates part of the trip. (ana.co.jp) For travelers connecting through Tokyo or Osaka, the practical question is no longer whether a power bank can fly, but how many and how it can be used once onboard. From April 24, the safest bet is a fully charged battery pack in your carry-on — and no plan to plug it in after takeoff. (mlit.go.jp) (jal.co.jp)
