Hiroshima (広島市, Hiroshima-shi, /ˌhɪroʊˈ[unsupported input]mə/, also UK: /hɪˈrɒʃɪmə/, US: /hɪˈroʊʃɪmə/, [çiɾoɕima]) is a major city in Japan and the capital of Hiroshima Prefecture. As of 2019, about 1.2 million people live here. The city's mayor since 2011 has been Kazumi Matsui. Hiroshima is the second largest city area in the Chugoku Region of Japan.
Hiroshima started as a castle town in 1589 on the Ōta River delta. After the Meiji Restoration in 1868, it quickly grew into a big city and industrial center. In 1889, Hiroshima officially became a city. It was an important military hub during the imperial era, playing a big role in wars like the First Sino-Japanese War and Russo-Japanese War.
Sadly, Hiroshima was the first city ever hit by a nuclear weapon. This happened on August 6, 1945, during World War II. At 8:15 a.m., the United States dropped the atomic bomb "Little Boy" on the city. Most of Hiroshima was destroyed. By the end of that year, between 90,000 and 166,000 people had died from the blast and its effects. The Hiroshima Peace Memorial (a UNESCO World Heritage Site) stands today as a reminder of the bombing.
Since being rebuilt after the war, Hiroshima has become the largest city in the Chūgoku region of western Honshu. It is a symbol of peace and hope.

A Look at Hiroshima's Past
Early Beginnings of Hiroshima
The area where Hiroshima is now was once a small fishing village. It was located along the coast of Hiroshima Bay. From the 12th century, this village became quite successful. It traded a lot with other parts of Japan.
From Castle Town to Modern City (1589–1939)
Hiroshima was officially founded in 1589. A powerful warlord named Mōri Terumoto built it on the delta of the Seto Inland Sea. He quickly built Hiroshima Castle and moved in by 1593. The name Hiroshima means "wide island" in Japanese.
After a big battle, Mōri Terumoto lost control of Hiroshima. The city was then ruled by the Asano clan from 1619 until 1871. In 1871, Hiroshima became the capital of Hiroshima Prefecture.
During the late 1800s, Hiroshima grew into a major city. Japan's economy was changing from farming to industry. A new harbor, Ujina Harbor, was built in the 1880s. This made Hiroshima an important port city.
In 1894, the San'yō Railway reached Hiroshima. A special rail line was built to the harbor for military transport during the First Sino-Japanese War. The Japanese government even moved to Hiroshima temporarily during this war. New factories, like cotton mills, also opened.
More industries grew during the Russo-Japanese War in 1904. This was because the city needed to produce military supplies. A building called the Hiroshima Prefectural Industrial Promotion Hall was built in 1915 to show new products. Today, this building is known as the A-Bomb Dome. It is a World Heritage Site and is kept as it was after the bombing.
During World War I, Hiroshima was a key military center. About 500 German prisoners of war were held on Ninoshima Island in Hiroshima Bay. The city continued to grow after the war.

World War II and the Atomic Bombing (1939–1945)
During World War II, Hiroshima was a very important military city for Japan. It had army headquarters and large storage areas for military supplies. Other Japanese cities were heavily bombed during the war, but Hiroshima was not. This made people think it might be a target. To prepare, children aged 11–14 helped clear houses to create firebreaks.
On Monday, August 6, 1945, at 8:15 a.m., an American plane called the Enola Gay dropped the atomic bomb "Little Boy" on Hiroshima. At least 70,000 people died instantly. This included thousands of Korean forced laborers. Less than 10% of those who died were military personnel. By the end of the year, the total number of deaths from injuries and radiation reached 90,000–140,000. About 70% of the city's buildings were destroyed.
After the bombing, information about the attack was kept secret by US military censors during the occupation of Japan. Films and casualty numbers were not released to the public until 1951. The book Hiroshima by John Hersey, which told the stories of six survivors, was very impactful in the US but was banned in Japan for a time.
The Oleander flower is the official flower of Hiroshima. It was the first flower to bloom again after the atomic bomb explosion in 1945.

Rebuilding Hiroshima: Postwar Period (1945–Present)
Soon after the bombing, on September 17, 1945, a strong typhoon hit Hiroshima. This caused even more damage and led to over 3,000 deaths and injuries in the prefecture. Many bridges, roads, and railroads were destroyed.
From 1945 to 1952, British Commonwealth forces occupied Hiroshima. The city was rebuilt with help from the Japanese government. The Hiroshima Peace Memorial City Construction Law was passed in 1949. This law provided money and land for the city's reconstruction.
In 1949, the design for the Hiroshima Peace Memorial Park was chosen. The Genbaku Dome (Atomic Dome), the closest building to where the bomb exploded that was still standing, became part of this park. The Hiroshima Peace Memorial Museum opened in 1955. Hiroshima's historic castle was rebuilt in 1958. A unique Peace Pagoda made of steel was built in 1966.
In 1949, the Japanese parliament declared Hiroshima a City of Peace. The city's mayor, Shinzo Hamai, led this effort. Because of this, Hiroshima became a popular place for international meetings about peace and social issues. The Mayor of Hiroshima is now the president of Mayors for Peace. This group works to get rid of all nuclear weapons worldwide.
On May 27, 2016, Barack Obama became the first sitting United States president to visit Hiroshima since the atomic bombing. In May 2023, the 49th annual G7 summit was held in Hiroshima.
