⚠️ Can you bring Cordless hair straightener (built-in battery) on a plane?
Not permitted — confiscated in Japan
The rule in detail
A cordless straightener whose battery cannot be removed is banned from both the cabin and checked baggage. Security at Japanese airports (Narita, Haneda, Kansai) confiscates and destroys them, so take a corded one instead.
Why the rule is written this way
It is classified as Allowed with conditions — check the rules because capacity, shape and quantity decide whether it passes, so the same object can be confiscated on one trip and not the next.
Measure it yourself before you leave, and if it is borderline ask the airline and keep the answer in writing. At the checkpoint the final call is the security officer’s.
What actually happens at the airport
- Check-in desk — this is the point of no return for your suitcase. Anything that may only travel in the cabin cannot be retrieved after this step.
- Security screening — if the X-ray flags a shape, the bag is opened. Most problem items are caught here.
- Extra check at the gate — on some routes there is one more inspection.
Confiscated items are rarely returned. If you are unsure, confirm the specification before you leave home.
Only models with a removable battery are allowed, and then the battery travels in the cabin
Other items in the same class
The items below are also classified as Allowed with conditions — check the rules. Quantity and volume limits differ per item, so check each rule separately.
| Item | Rule |
|---|---|
| Liquids / gels / cosmetics | Cabin: 100ml or less / checked: no limit |
