I'd like physical but unless the european copy has jp language enabled I will probably go digital, as even with preorder I would be waiting a month most like for a jp copy to get here, unless I could take a trip there but, expensive times lol
I have to explain something to you because you have made it clear a few times that you are planning on making things needlessly difficult and expensive for yourself. Not to mention a colossal waste of your time.
There exists only one SKU for Switch games. The SKU is universal, as it covers all regions at once. There technically is no American copy of Breath of the Wild, just the same as no European or Japanese copy exists. This is because of the Switch being openly region free and all regions sharing the same version of the game between all regions.
For example: Okami HD released on the Switch eShop in the US, but Japan got a physical edition. Because I didn't intend on playing the game anytime soon, I ordered a copy of the physical edition. Upon loading the game card in my Switch, I was not presented with the Japanese version of Okami, but the same exact version of the game that was available on the eShop for months prior. Why is that? Because it shares the same SKU as the version of the game that is available on all eShops around the world, and the version of the game that is loaded is not determined by the region in which you bought the game from, but the region in which your Nintendo account is set to.
In a nutshell, if you import a physical copy if Animal Crossing from Japan and you play it on your main profile that is set to your home region(something I believe that cannot be changed now on current firmware), you aren't going to get the Japanese version of the game, but the same exact game that you could walk out to your local brick and mortar and pick up off the shelf.
It isn't like the past with the 3DS where American and Japanese copies differed from each other. Switch games are the same no matter where you buy them from, and the version you get to play is entirely dependent on your own console settings.
In closing, if you import you're only going to get the box art with a Japanese logo and a different sticker on the game card. The game that loads on your Switch will be the European version with whichever region language is your native. The only way you circumvent this is create a new profile on your Switch and set the region to Japan, then all of your games will load with Japanese text if available.
