As you probably already know, the PlayStation 5 is not an easy console to find — and this is just about as true in Japan as it is here in the West. Naturally, Sony's doing all that it can to sell as many current-gen consoles as possible — but because of ongoing chip shortages and other persistent manufacturing issues (largely caused by the pandemic), it's still going to be while before Sony is able to match consumer demand.
A new incentive could help ease the situation, however. As reported by Yahoo! Japan a few weeks back (sorry we missed it!), Sony is currently working with retailers to tackle PS5 scalping in Japan. A quick explanation just in case: a 'scalper' is a person who snaps up limited stock in order to resell it at a higher price — and the PS5 has been a key target for scalpers since its launch in 2020.
Anyway, Sony's providing retailers with official seals, which are applied to PS5 packaging. The idea is that when a PS5 is sold, the retailer breaks the seal so that the PS5 can be identified as sold and 'opened'. The seal itself is apparently difficult to remove, so a boxed PS5 that's been sold be scalpers should be easy to spot because of the seal or the damaged packaging that a removed seal has left behind.
It's a bit unclear how far this incentive's reach is within Japan, but it sounds like a decent enough plan. Hopefully it's had some degree of impact on scalping market, and more PS5s are finding their way to regular customers.
