A big war ended long ago. 

A big war was ending. 


A big war was ending in 1945. Japan had lost many battles. Their ships could not fight well. They also lacked oil for power. 
Leaders from the United States, China, and the United Kingdom met. They asked Japan to surrender. They said Japan must stop fighting right away. 
In August, two atomic bombs were dropped on Japan. One hit Hiroshima. The other hit Nagasaki. 

Emperor Hirohito made a big choice. He told his people to accept the peace terms. He spoke to them on the radio. 
On September 2, the war officially ended. Leaders met on a large ship called the USS Missouri. They signed papers to finish the war. 
By 1945, the war in the Pacific was reaching a turning point. Japan had lost many battles over two years. This included fights in the Philippines and the Marianas. 

Leaders from the Allied powers had a plan for peace. The United States, China, and the United Kingdom met at the Potsdam Conference. In July 1945, they issued the Potsdam Declaration. They asked Japan to surrender without any conditions. If Japan did not agree, they warned of utter destruction. Inside Japan, leaders were divided on what to do. Some wanted to fight one last big battle. Others wanted to find a way to make peace.
In August 1945, several major things happened at once. On August 6, the United States used an atomic bomb on Hiroshima. 

Emperor Hirohito played a very important role in the end. He ordered his leaders to accept the terms from the Allies. Some military members tried to stop this with a coup. However, the coup failed and the surrender went forward. 
The war officially ended with a formal ceremony. This took place on September 2, 1945. 

The surrender of the Empire of Japan marked the formal conclusion of World War II in the Pacific. This surrender happened in stages during the summer of 1945. It began with a public announcement by Emperor Hirohito on August 15. The process ended with a formal signing ceremony on September 2, 1945. 
By mid-1945, Japan's ability to fight was failing due to several factors. The Imperial Japanese Navy (IJN) could no longer conduct major operations. Many of their ships were damaged or lacked enough fuel to move. 
To force a conclusion, the Allies issued the Potsdam Declaration on July 26, 1945. This document called for the unconditional surrender of Japan. It warned that the alternative was "prompt and utter destruction." Inside the Japanese government, the Supreme Council for the Direction of the War held power. This group, known as the "Big Six," included the Prime Minister and top military leaders. 
Two main groups emerged within the Japanese leadership. The "peace" camp wanted to find a way to negotiate. They hoped the Soviet Union would act as a mediator to help Japan secure better terms. The "hardliners" wanted to fight one last decisive battle. They believed a massive defense of the Japanese home island of Kyūshū would force the Allies to offer more lenient terms. Their plan, codenamed Operation Ketsugō, involved using thousands of kamikazes and suicide motorboats to attack Allied ships. 
In August 1945, several rapid events pushed Japan toward surrender. On August 6, the United States detonated an atomic bomb over Hiroshima. On August 9, the Soviet Union declared war on Japan, breaking a neutrality pact. 

Emperor Hirohito eventually intervened to end the conflict. He ordered the Supreme Council to accept the terms of the Potsdam Declaration. This decision faced resistance from some military members. A group of hardliners attempted a failed coup d'état to stop the surrender. 
The formal end of hostilities occurred aboard the U.S. Navy battleship USS Missouri.
