Japan is introducing a nationwide ban on power bank usage during flights from April 2026, tightening aviation safety rules and limiting how many portable chargers passengers can carry due to rising lithium-battery fire risks. Travel agents and airline partners must prepare for this change.

Japan’s 2026 Power Bank Ban: What Travel Agents, Corporates & Airlines Must Know

Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has confirmed a new aviation safety policy that will ban the use of power banks onboard aircraft starting April 2026. This significant change aims to reduce fire hazards linked to lithium-ion batteries — a growing concern in global air travel.

As B2B travel professionals, consolidators, corporate travel planners, and airline partners, understanding this new rule is essential for advising clients and updating travel compliance guidelines.

What the New Rule Actually Says

In-Flight Use of Power Banks Banned

From April 2026, passengers will not be allowed to use power banks to charge devices during flight — whether through USB cables or onboard power outlets.

Carry-On Capacity & Quantity Limits

While power banks can still be carried in carry-on luggage, there are strict limits:

Up to 2 power banks per passenger
Each must not exceed 160 watt-hours (Wh)
Devices above 160 Wh remain fully prohibited

These align with existing international safety protocols.

Applies to All Flights To/From Japan

The ban covers all international and domestic flights that depart from or arrive in Japan — regardless of carrier nationality.

Why Japan Is Taking This Step

Rise in Battery-Related Incidents

Lithium-ion batteries — the core technology in power banks — can overheat, emit smoke, and in some cases, catch fire. Japan’s safety authorities have seen a sharp increase in battery accidents in recent years, prompting regulatory action.

Real-World Incidents Highlight Risk

Incidents like the Air Busan Flight 391 fire in South Korea, linked to a power bank stored in carry-on baggage, emphasize how severe these hazards can be and why stricter oversight is emerging globally.

Aligning with Global Safety Guidance

The International Civil Aviation Organization (ICAO) has already discouraged in-flight charging of portable batteries. Japan’s regulation mirrors this international direction and may influence other regions.

What This Means for Travel Industry Stakeholders

Travel Agents & Consolidators

Corporate Travel Planners

Airlines & Ground Staff

Practical Tips for Travellers

Charge all devices fully before boarding
Confirm watt-hour rating of portable batteries
Keep power banks easily accessible (carry-on, not checked baggage)
Encourage use of aircraft USB or AC outlets for device charging

Key Takeaways

Japan’s April 2026 power bank ban marks one of the most stringent portable battery safety measures in aviation. While passengers can still carry approved power banks, they cannot use them mid-flight, reshaping passenger expectations and planning. For travel businesses and airline professionals, proactive communication and compliance support will be critical to smooth travel operations.
