You can see Max standing at the side of the memorial and the Genbaku Dome. Rex told Max that in August of this year the U.S. for the first time joined the Japanese in their memorial ceremonies.
As Max was listening to Rex talk, he was thinking of the ceremony going on at Ground Zero that very day. He thought, "Here we are at Japan's Memorial to their dead as the names are read of those who died on 9/11 back in New York. What irony!"
Hiroshima Peace Memorial, commonly called the Atomic Bomb Dome or A-Bomb Dome (原爆ドーム, Genbaku Dōmu), in Hiroshima, Japan, is part of the Hiroshima Peace Memorial Park and was designated a UNESCO World Heritage Site in 1996. The building serves as a memorial to the people who were killed in the atomic bombing of Hiroshima on August 6, 1945. Over 70,000 people were killed instantly, and another 70,000 suffered fatal injuries from the radiation.
The Genbaku Dome, originally close to Shima Surgical Clinic, initially was scheduled to be demolished with the rest of the ruins, but the fact that it mostly was intact, use delayed these plans. As Hiroshima was rebuilt around the dome, it became a subject of controversy; some locals wanted it torn down, while others wanted to preserve it as a memorial of the bombing.
