A resealed box is one that has been opened, searched or had its best packs swapped for weaker ones, then wrapped up again to pass as new. Popular Japanese sets sell well above their original price, so there is real money in doing it. It became common enough in Japan that Pokémon changed the design of the box itself in 2022, which also gives you the most useful check of all.
Check the perforated top
From late September 2022 Pokémon Japan began switching its expansion boxes to a new design. The old box had a tuck flap that could be lifted out and pushed back without leaving a mark. The newer box opens along a perforated strip that has to be torn, the way many snack boxes open, so a box that has been opened stays visibly opened.
If the box in front of you has that strip, it should be completely intact with no tears, cuts or glue anywhere along the line. A torn or reglued strip means the box has been opened, however good the wrap looks.
Look at the shrink wrap

Factory wrap goes on in a single neat seam, usually along the bottom of the box. Be wary of wrap that is held down with tape, shows traces of glue, sits in more than one layer or looks melted and bunched up at the corners. Compare it with photos of a box from the same set that you know is genuine, since packaging details vary from set to set.
A Japanese box with no wrap at all is not automatically a reseal. Some shops in Japan cut the wrap off at the counter so a box cannot be passed off as new later, which is part of why the perforated top matters so much.
Check the box and the packs
In a genuine box the packs sit in neat rows facing the same way with nothing rattling around loose. Each pack should be sealed cleanly at both ends. Treat any pack that looks reglued or sits loosely in its wrapper with suspicion.
Counterfeit boxes usually give themselves away in the printing, with blurry text, colours that look washed out and Japanese characters that do not match a box you know is real. If the set name or set code on the box does not match a set that was actually released in Japan, walk away.
Buy from a seller who stands behind it
The best protection is a seller who states plainly that a box is factory sealed and will put it right if it turns out otherwise. In Australia the Australian Consumer Law backs you up here, because goods have to match their description. A box sold as sealed that turns out to have been opened entitles you to a remedy from the seller. A price far below what everyone else charges for the same sealed box is the other warning sign worth taking seriously.
