Nope. Nintendo DS was made at Foxconn. Nintendo 3DS was also made at Foxconn. The Wii was made at Foxconn. And Nintendo Switch is made at Foxconn.

They're assembled at Foxconn, the components themselves are typically made in much less formidable conditions, if you can believe it.

Maybe you read "designed in Japan" on the box, similar to how Apple likes to print their neat "designed in Cupertino" line on the package.

I read somewhere that 40% of all (consumer) electronic devices worldwide go through Foxconn. Pretty much everyone uses them. Don't see a proud "made in USA" or something like that on the website? Foxconn, most likely.

BTW some PS4s are made in Japan
