The Japs also had huge submarine aircraft carriers that they planned to attack the Panama Canal and possibly US cities with!
Yes, Japanese I-boats had the range to cruise the West Coast. A couple even shelled the mainland.
Here is a brief but good story on that WW II secret mustard gas disaster, with fine photos.

And given the distance, would they even have had enough oil to have made the journey?

Read it again, please. Especially the word oil.
Santa Anna learned that from Houston.
Yeah, you should always make sure that the enemy knows that if they surrender they will survive. Killing prisoners is a bad practice for practical as well as moral reasons.
It really does read like you are questioning if Japanese submarines had the oil capacity to have the range to make the journey since Japanese I-boats could easily have carried a 1940’s atomic weapon. In any event, submarines don’t require all that much oil. The Type-B Mod. 2 (I-54) had a fuel capacity of 842.8 tons and a range of 21,000 nmi (39,000 km) at 16 knots (30 km/h). The I-58, which survived the war and was returning from patrol when Japan announced its surrender on August 15th, was a submarine of this class best remembered for sinking the heavy cruiser Indianapolis as it was sailing from Guam to Leyte on July 29th, 1945 the day after it had delivered parts for the atomic bombs to Tinian. By way of contrast the Indianapolis needed 1,500 tons of fuel oil for a range of only 13,000 nmi (14,960 mi; 24,080 km) at 15 knots (17 mph; 28 km/h).
No, I’m questioning if Japan had that much oil available to fuel a submarine for such a futile mission in late summer of 1945. Everything I’ve read says that the American blockade of Japan had caused an extreme shortage of fuel in Japan by that time.
