Japan's pacific campaign

1. When the Americans cracked one of the codes that the Japanese used to sending secret messages on October 1940 that's how led to the war in Asia.





2. The advantages to the island hop plan were that he would seize islands that wasn't defended but were closer to Japan. The disadvantages were that they had trouble seizing guadalcanals airfield.


3. I think the reason the Japanese changed their approach in war is because they kept losing a whole bunch of soldiers and they believed that they were going to win.
