How far could Japan get towards the west coast after Pearl Harbor

There's also the Drake Passage and Strait of Magellan.

They could also take the long route, from the East Coast to South Africa, across the far southern Indian Ocean to Australia, and then northeast into the Pacific.

By the standards of this challenge, the Japanese could have probably destroyed both the Drake Passage and the Strait of Magellan as well, forcing the Americans to supply Hawaii by going around the world the other way.

Except that both are far harder, and in the case of the Drake Passage, nigh impossible to destroy - no dams or locks to blow up, no avalancheable vertical cliffs flanking narrow cuts, it's all entirely at sea level...

Unless Chile joins the Axis, the Drake Passage and Strait of Magellan are staying open. Heck, even in the ASB event that Chile DOES join up, the Drake Passage is probably still doable, and the Allies might even be able to force the Strait of Magellan.

Sarcasm was meant...

Anyway, my question is whether 21st century Chile and Argentina working together could close the Drake Passage. OTOH, if they tried to do that, more vulnerable targets like Buenos Aires and Santiago would be attacked to try to alter the issue....
 
But how plausible would it be for the Japanese to send commando teams to the west coast to cause mischief? Not overly successful, but enough to give the US a headache.

Given that all the Japanese are in camps, they're going to stick out quite a bit. Wont have local support and they're gonna stir up a hell of a hornets nest. Not sure they could really achieve anything but pissing the US off and making things worse for Japanese-Americans.
