Hi,
IIRC, the Japanese were enamored with complex battle plans. There was a Bantum War Book (c1970) detailing the Aleutian campaign. It goes into further details about your Aleutian summary (Sorry I can not recall the name of the book right now). The worst problem with flight operations there were the sudden weather changes.
When the B-29 was developed, the realization that they would need weather reports for flight planning.
An OSS team was sent in to place a weather station in the Gobi Desert. When they were placing the weather station and before the B29 was test flown, It was intended to bomb the Japanese northern home island from the Aleutians. As things went, the island hopping had moved close enough to the Japanese home islands that all flights there were from the middle and southwestern Pacific.
For a long time, the only flyable Japanese Zero came from the Aleutian islands. It had to crash land and flipped over in a marshy bog area on one of the islands.
FWIW
