Naval operational range was vitally important in WW2. that is why the US had to have the campaign of islandhopping.
If you look at for example the IOWA class of US battleships, they had an operational range of 23000 KM.
The distance from San fransico to Tokyo is about 8200 km. If you assume it does not travel in a straight line, but does a zig zag pace to avoid submarine torpedoes, the distance will be about 12000 KM. However, it would be very stupid to travel just in the sortest route, they would be way to easy to find for japanese planes, so they would probably have to make a detour, so we can reasonably assume they would travel 14000-16000 KM to get there. When they get there, they would have to probably travel around alot to look for targets, I will add 700 KM/ day. For a 2 week raid, that works out to about 10 000 km. Then they will have to travel back again. This makes their total journey at about 40 000 KM. This is why they operated from Hawaii, and later from Guam.
The seazones is a small sense of trying to capture scales and the limited ability of fleets to project power. You can project power from hawaii to the sea of japan. You can not do the same thing from San fransisco.
