Topic: region locking games!

i need help i can get a Japanese super smash bros key and put it on my account by changing the region.

the reason i am doing this is its half the price of the European eshop

anyway my question is will it change language to English when i change the region of my account back to Europe and will i be on the European servers??

The Japanese version will run fine, the Switch doesn't have region locking.

Just be aware that you'd have to purchase all your DLC from the Japanese eShop as well.

If you have a game in one region DLC has to be from the same region. I bought the Breath of the Wild DLC for a friend and it didn't work because they had an American Switch, and I bought it on the British Amazon.
