It would have been better for the Japanese if they were to destroy the repair facilities and fuel farms at Pearl. Then if they took Midway, they could have been in decent positon to control the pacific. It would have been a difficult task to resupply, but it would have been easier than Hawaii. Also they would ot need the forces required to defend an area like Hawaii.

Without the facilities that were are Pearl to fix and supply the ships, the fleet would have been moved to the mainland. This would severly restrict the ability to strike in the Pacific. Aircraft at Midway would have been able to protect Japanese ships, who would have deterred any attempts at reconstruction of Pearl. However, such imagination and ability to develop the proper equipment to maintain such an operation was lacking in the Japanese fleet. If Naguma had not been allowed to lead the fleet, or had listen to Fuchida it might had extended the war for years. The big problem was that Japan never properly provided for the training and replacement of air crews.
