Question

What was the last island the Allies captured before preparing to attack mainland Japan?

Answer 1

Okinawa

Step-by-step explanation:

Because On April 1, 1945, more than 60,000 soldiers and US Marines of the US Tenth Army stormed ashore at Okinawa, in the final island battle before an anticipated invasion of mainland Japan. After a largely unopposed initial advance, US forces soon encountered a network of Japanese inland defenses.
