The Mazda Motor Corporation, founded in Hiroshima in 1920, still retains its corporate headquarters in the city of its origins. In addition to the headquarters, Mazda owns a large plot of coastal land which accommodates research and development laboratories, factories, and shipping facilities. The company museum and part of a factory are made available for public viewing.
Like Toyota to Nagoya, Mazda plays a large role in Hiroshima's economy. Although Mazda is not as large as Toyota, it still produces over a million cars a year and is an innovative player in the Japanese auto industry. For instance, in 1991 Mazda became the first and only Japanese company to win the Le Mans Grand Prix. Continuing efforts to create more efficient vehicles include improving its version of rotary engines. https://www.japan-guide.com/e/e3405.html
The museum continues to spearhead the global movement towards nuclear disarmament and lasting world peace. The museum is divided into the East Building and the Main Building. In the museum, the history of Hiroshima before and after the bombing is exhibited with pictures, movies and displays. Also, there are some items that convey the devastation caused by the atomic bomb. In spring, the Peace Park is covered with cherry blossoms. http://visithiroshima.net/things_to_do/attractions/museums/hiroshima_peace_memorial_museum.html
