For the first time, Nintendo has done away with region locking with the Switch. That means we can access any region's eShop – and purchase games only available in certain regions – very easily. Well, almost.
While your Switch has its own region setting, this doesn't affect what store you see – rather, it's tied to your account. So if you want to have a gander on what's available in the US or Japan, you just need to create a new Nintendo Account, tell a little white lie about what region you're in, and link it to a new profile on your Switch.
Creating a new account is fairly easy – just head on over to accounts.nintendo.com and select 'Create a Nintendo Account'. The only caveat is you'll need to have a separate email address for each account you create, so unless you've still got access to your embarrassing 'xX_Em0Chick_Xx' or 'C00lD00d69' Hotmail account from the early 2000s, you'll need to set up a new email address, too.
You'll have to fill in the usual details – name, date of birth, etc. It doesn't matter what you choose. The only important part is the Country/Region of Residence. If you want to access the North American eShop, choose United States. If you want Japan, well, choose Japan.
Once it's set up, you'll need to check your emails for a confirmation, and then you're ready to link it to a new user account on your Switch. Head to System Settings, then User, and select 'Add New User'. Sign in with the account you've just set up, and voilá, you're all done.
Now, when you click on the Nintendo eShop icon on your home screen, you'll be asked 'Who is using Nintendo eShop?', and can choose which region of the store you want to see by selecting the appropriate user.
Already, there are different games available across the regions. Yesterday, America had The Binding of Isaac, Little Inferno, World of Goo and Human Resource Machine added to their store. These will be coming to the European store at some point, but if you're impatient, you may want to grab them sooner. Japan, on the other hand, has Puyo Puyo Tetris, Disgaea 5 and Dragon Quest Heroes, among a couple of other titles that haven't made it to the West yet.
You'll need to acquire eShop credit for each region though – and if you're browsing the Japanese store, everything will be in Japanese (d'uh). Still, it's nice to finally be able to access different country's eShops after Nintendo's long history of region-locking.
