The allies adapted the strategy of island hopping in the war of 1945
the advantage of this strategy was that the allies encountered less japanese resistance. they were also able to obtain bases in order to japanese cities that housed wartime factories

Actually, the Allies adapted the strategy of island hopping in WWII because it saved lives, time, effort, money, ammunition, food, ships, and everything else. In taking only key islands, the other islands would be cut off from the Japanese mainland and basically all supplies and equipment. Island hopping also allowed the US to quickly go through the places without spending much time liberating each one. It help end the war sooner, and the US were able to complete their objective much more quickly.

hope this helps
