There is good evidence that Japanese made it all the way to New Mexico, and settled down with a pueblo Indian tribe.

The first evidence is the tribes unique DNA, unlike all other tribes in the area, but a very close match to ancient Japanese DNA. The second evidence is that their unique artistic styles bear strong similarities with ancient Japanese art.

There is a tribe in Peru that is pretty clearly proto-Japanese. Same rare DNA defect.

But they did not "discover" Peru. They were probably refugees that washed up on shore.
