buccel Apex will still be playable on the Switch, just what is happening is that on August 4th, 2026, the Switch 1 version will be discounted, where you would then need to own a Switch 2 in order to keep on playing on the Nintendo Switch platform.
All your Apex progress and data is tied to your EA Account, and that same EA Account is linked to your Nintendo Account, so when you sign into a Switch 2 System with your Nintendo Account, it should log you into the same account that you are using to play Apex right now.
Furthermore, your Apex Coins and Exotic Shards will move over to the Switch 2, (however keep in mind that since you are in Japan, the local laws for your area does require digital currencies to expire after a set timeframe, (so be sure to use those before those expire)).
