Needles and syringes on flights in and from Japan

The rule for needles and syringes comes from the Civil Aviation Bureau's list of restricted items and is the same on domestic and international flights.

Insulin pens, EpiPens, lancets and the paperwork for needles

Japan's list files needles with sharp objects, then makes room for the ones a patient uses on themselves.

Lancets for a glucose meter have their own row
Next to the injection needle rows, in the section for objects with markedly sharp tips, Japan's list has a line for the blood-sampling needles used to measure blood sugar. It is marked allowed both carried on and checked, with no remark. Narita Airport confirms that blood glucose meters can be carried on board, and the TSA lists the Blood Sugar Test Kit as allowed in both bags.
Insulin, its pump and its cooling pack
Japan's liquids list excepts the ice or gel that keeps insulin cold, on condition that it is packed with the medicine. The TSA asks for insulin to be placed in a bin separately for X-ray screening, and says pumps and supplies must be accompanied by insulin, with insulin in any form or dispenser clearly identified.
A medical purpose does not cover every sharp instrument
The exception is written for needles that inject prescribed medicine. Japan's list marks surgical scalpels as checked baggage only and adds that medical ones, whether surgical, ophthalmic or dental, cannot be carried on. Australia's Home Affairs department names scalpels among its prohibited items too, and lists hypodermic needles carried without proof of medical need among sharp items that can cause harm by penetration.

Needles and syringes: the rule country by country

In the United Kingdom the authority's page lists needles and syringes as allowed in carry-on.

Each row comes from that authority's own page. Airlines can be stricter, and the screening officer has the final say.

If security in Japan will not let needles and syringes through

What to do
Move needles and syringes to the bag you check in before you reach security. Narita Airport states that anything given up at the checkpoint is discarded and cannot be returned.

Frequently asked questions

Can you bring needles and syringes on a plane?

On flights in and from Japan: Yes for needles you use yourself to inject medicine a doctor prescribed for home use, such as insulin, interferon or adrenaline. Other injection needles cannot be carried on unless a doctor or nurse will use them on board. In checked baggage: Yes.

Can you carry an EpiPen on a plane?

Yes. Japan's list allows needles used to inject drugs that a doctor has prescribed for self-injection at home and names adrenaline preparations among them, next to insulin and interferon. The TSA lists EpiPens as allowed in carry-on and checked bags, and its entry says larger amounts of medically necessary liquids must be declared at the checkpoint. CASA lists EpiPen and other similar medical delivery devices as items that can be carried on or checked in.

Are sewing needles treated like injection needles at airport security?

No. Japan's list has separate rows for sewing needles and safety pins, both allowed in carry-on and checked baggage with no condition. GOV.UK lists a sewing needle as allowed in hand and hold luggage. The TSA allows sewing needles in both bags but sends cutters that contain blades to checked baggage. Taiwan's CAA is stricter with metal knitting needles, which it lists among piercing tools for checked baggage.

Do you need a doctor's letter to carry needles in carry-on?

In Australia, yes: the Home Affairs department says that if you travel with hypodermic needles you must have a doctor's letter with you. Japan's list sets no such condition for self-injection needles. Narita Airport asks you to present a medical certificate or prescription if you have one, and otherwise to inform the security inspector. The TSA recommends, but does not require, that medication be labelled.

Does the TSA allow needles and syringes in carry-on bags?

Unused syringes are allowed in carry-on when accompanied by injectable medication, and you must declare them at the checkpoint. Used syringes must be in a Sharps disposal container or similar hard-surface container. Allowed in checked bags.

The United Kingdom: Hypodermic syringes are allowed in hand luggage and hold luggage.

What is the rule for needles and syringes on flights from Taiwan and Australia?

Taiwan: Medical injection needles are listed as sharp objects that must go in checked baggage. Needles you must use during the flight for medical reasons may be carried on board if you declare them at the security checkpoint and get approval. Australia: Carry-on: allowed only with proof that the needles are medically necessary for you or a person in your care, and you must have a doctor's letter with you; otherwise they are prohibited.
