Can you take a poster tube on a plane? The rule in Japan

Poster tubes on flights in and from Japan

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

Poster tubes and scroll cases: carry-on and checked baggage in Japan
Where	Allowed?	What applies
In the cabin	Yes, within limits	Storage tubes for posters and scrolls: yes if 70cm or less; a longer one only if it is paper or plastic and judged not to be a weapon. Hanging scrolls and tapestries: yes if the rod is 65cm or less, or made of plastic.
In checked baggage	Yes	Yes.

The security rule is about length. Your airline's carry-on size limit is a separate check, and a long tube can fail that one.

A poster tube is measured end to end, a scroll by its rod

Japan's list gives the tube and the scroll inside it separate rows, with different lengths and different exceptions.

The last rows of the list: The storage case for posters and hanging scrolls and the scroll itself close Japan's list, at the end of its section for other items. Both are marked × for carry-on and ○ for checked baggage, and both get their cabin allowance from the remarks column. Tapestries share the scroll row.
More room than the usual 60 cm: Many long objects on Japan's list are cut off at 60 cm for the cabin: folded tripods, beach parasols, massage sticks, even noodle rolling pins. Poster cases and scrolls get more, 70 cm for the case and 65 cm for the rod that a scroll or tapestry hangs from.
Paper and plastic can go past the limit: The exception for a longer case is a judgment, not a measurement: a case made of paper, plastic or similar material may exceed 70 cm when it is judged not usable as a weapon. The list's opening notes say the airline or the security screener judges, by material, strength and shape. For scrolls the wording is firmer: a plastic rod may exceed 65 cm.
Checked baggage and very long tubes: Both rows are ○ for checked baggage, with no length written. Narita Airport explains the difference: carry-on bags are inspected for items that can be used as a weapon, checked bags for goods prohibited from transport. Its FAQ also says that for items that are excessively long, passengers should consult the airline.

Umbrellas

If security in Japan will not let poster tubes through

What to do: Move poster tubes 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 take a poster tube on a plane?

On flights in and from Japan: Storage tubes for posters and scrolls: yes if 70cm or less; a longer one only if it is paper or plastic and judged not to be a weapon. Hanging scrolls and tapestries: yes if the rod is 65cm or less, or made of plastic. In checked baggage: Yes.

Is the 65 cm limit for a hanging scroll measured on the scroll or on its rod?

On the rod. Japan's list words the limit as the length of the rod: a scroll whose rod is 65 cm or less can be carried on. If the rod is made of plastic, the scroll can be carried on even when the rod is longer than 65 cm. Tapestries are in the same row and are measured the same way.

Does a cardboard poster tube longer than 70 cm have to be checked in Japan?

Not automatically. Japan's list lets a case of paper or plastic longer than 70 cm into the cabin when it is judged not to be usable as a weapon, a call made by the airline or the security screener. The row attaches no such condition to a case of 70 cm or less. Narita Airport says to consult the airline about items that are excessively long.
