Yes if you jailbreak it
It removes the region lock and you can set the system language to english. The eShop was shutdown already so that doesn’t matter
Just seconding this real quick; I bought New 3DS systems in both standard and XL sizes from Japan. It's easy enough to jailbreak/install CFW on them and get it set up so you don't have to worry about it. (Note this was well before tariffs and other import problems, so I have no idea what the market looks like and if there are any caveats to be aware of if you live in the US.)
