This one's pretty simple — food, glorious food of all kinds, from international delicacies to local favorites, from roasted slabs of meat and seafood to delicious vegetarian-friendly dishes and desserts, served in stalls lining the moat of Hiroshima Castle and parts of Chuo Park. There's a flea market as well, and usually some cultural performances at the castle in the evening.
原爆ドーム Genbaku Dōmu
The skeletal remains of the dome are the most recognizable symbol of the atomic bombing in Hiroshima. In another lifetime, the building was one of the city's best-known sights for an entirely different reason; designed by Czech architect Jan Letzel in 1915, the Hiroshima Prefectural Commercial Exhibition Hall (and its fanciful green dome) had a bold European style in a grimy, crowded city with few modern flourishes. Because the explosion took place almost directly above the building, the walls remained largely intact, even as the dome shattered and the people inside were killed by the heat of the blast. Initially, as the city rebuilt, it was left alone simply because it was more difficult to demolish than other remains in the area; gradually, the A-Bomb Dome became the symbol it is today. The "Hiroshima Peace Memorial" was declared a UNESCO World Heritage site in 1996 amid some controversy — the United States and China both voted against the nomination for reasons related to the war. Today, the benches around the Dome are a favorite spot for Hiroshima natives to read, eat lunch, or simply relax.
One block east of the A-Bomb Dome (outside Shima Clinic) is a plaque which marks the exact point above which the bomb exploded.
(原爆の子の像 Genbaku no ko no zō
Perennially draped in thousands of origami paper cranes folded by schoolchildren across Japan in the memory of the young bomb victim Sadako Sasaki (see Literature). You can bring your own origami cranes and donate them to the memorial.
Commemorates the 6,300 students who were conscripted to work in munitions factories and killed by the atomic bomb. There are statues of doves scattered throughout its five levels; at the base is a beautiful Kannon statue, always draped with origami cranes.
The Peace Memorial Hall is dedicated to collecting names and photographs of people who died in the blast. The entrance of the memorial hall leads downward to a quiet hall for contemplation, and then back up again to a set of kiosks with compelling stories and recollections from survivors (in English and Japanese). Like the Cenotaph and the Peace Memorial Museum, it was designed by architect Kenzo Tange.
平和記念資料館 Heiwa Kinen Shiryōkan
This heart-wrenching museum documents the atomic bomb and its aftermath, from scale models of the city "before" and "after" to melted tricycles and other displays and artifacts related to the blast. Some are extremely graphic, evocative, and quite disturbing. The rest of the museum describes the post-war struggles of the hibakusha and an appeal for the abolition of nuclear weapons in the world today. Be warned: a visit here, while absolutely worthwhile, will ruin your day. Allow plenty of time afterward to decompress.
