In this timeline, Japan wasn't forced to demilitarize, so they have quite a large military. Sure, they may eventually try to integrate Alaska as a state, but they have the Treaty with Japan to worry about. Also, they had gotten the nuke a little later than OTL, and while they did annex the land from Cuba and the Hispaniolan Alliance, that was the last of their expansionism, as sure, the Soviet Union was weaker, but they did eventually become stronger, and when they collapsed, they were about as strong as OTL WW2 Soviet Union, so the Cold War still occurred, with it being much more successful for America. America was just not focused on Japan and Alaska, as they have had more important issues than integrating 20,000 people in a frozen wasteland with only one purpose that America did not need it to be a state for: gold and oil.But… America has nukes. And Alaska has gold and oil. If we’re still in the part of the show where nations annex land, shouldn’t Congress be itching for a rematch with Japan?
Eventually, they may renounce the treaty preventing that, and Japan would do nothing, except maybe request for Taiwan back. That would be a Philippine issue, however.
tl;dr America outgrew their annexing phase after the Hispaniola War, when they got nukes. Also, Alaska was not worth a war with Japan. Maybe in the future, but not for a while yet.
