The ninth exhibit is Death at Japanese Doorstep, the first assault on Japanese soil. The last two D-Days, Okinawa and Iwo Jima, proved to be some of the most fierce fighting in world history. The Japanese had built extensive underground defense tunnels and caves, which are realistically portrayed in this part of the exhibit. You also learn about all of the Medal of Honors that were given out. There are 27 at Iwo Jima alone, and you're introduced to the Navajo code talkers who played a pivotal point in this part of the war. As you walk into the last exhibit, you realize that Downfall, Endgame Against Japan, is a different piece of this exhibit. The music is much more somber and reflective as you watch on the humongous video screens what occurred at the end of the war, including the firebombing by United States forces of hundreds of Japanese cities.
