The new model of PS5 for Japan comes with a price drop (from ¥72,980 (~$473) down to ¥55,000 (~$350)) and can only be used in the Japanese language, also requiring the use of a Japanese PSN account. This renders the unit almost useless outside of the country, as Sony specifically targets sales improvements in the Japanese market. Nintendo does offer a similar version of the Switch 2, and its sales successes are clear to see.

Here’s how the Japanese hardware sales look overall for 17th-23rd November (via Gematsu):

Switch 2 – 126,953
PlayStation 5 Digital Edition – 23,381
Switch OLED Model – 12,486
PlayStation 5 Pro – 11,367
Switch Lite – 10,908
Switch – 5,976
PlayStation 5 – 2,235
Xbox Series X Digital Edition – 201
Xbox Series X – 118
Xbox Series S – 30
PlayStation 4 – 17
