Great Depression, Militarism and World War II in Japan

In 1929 a money crash in the USA became a world-wide Great Depression. In Japan, silk prices fell, farms and factories suffered and many people lost work. Army leaders gained power by promising a way out, party government ended, and Japan went to war in Asia and then in the Pacific. The war ended in 1945 after great loss of life and homes.

🎬 Step-by-step story

  1. 1929: the economy looks healthy. Factories are busy, so the green Output bar is tall. Few people are jobless.
  2. 1929 to 1931: the Great Depression. Output falls and the grey Jobless bar shoots up. Silk and rice farmers also lose their income.
  3. 1931 to 1936: army officers say, "Take land abroad and the economy will recover." The red Army bar grows as party government weakens.
  4. 1937 to 1941: war with China widens, then the Pacific War starts. Output is used for weapons, and the Army bar becomes very tall.
  5. 1945: the war ends. Cities, homes and factories are damaged. Millions of people have died. The black Damage bar is full.
  6. Your turn: drag the year slider from 1929 to 1945. Watch all four bars and read the event under the picture.

🤔 Common doubts, cleared

Why did a crash in the USA hurt Japan?

Because countries trade. When Americans bought less silk, Japanese farm families lost income. Watch the Output bar fall and Jobless rise.

Why did people listen to the army?

They were afraid and wanted a quick answer. The army promised land and resources abroad. The red bar grows as other voices weaken.

Did war help the economy?

For a short time output rose, but it was used for weapons. In the end the damage was far greater. See the tall Army bar and then the Damage bar.

How many people died?

More than 70 million in the world. Most were ordinary people. The Damage bar shows the size of the loss.

Which year was the worst for jobs?

Around 1931. Set the year slider to 1931 and read the Jobless bar.

The Great Depression reaches Japan

In October 1929 share prices in New York crashed. Banks closed and factories stopped. Because countries trade with each other, the trouble spread. People call this world-wide slump the Great Depression.

Japan was hit in two ways:

In 1931 poor harvests in the north-east made life harder. Many workers lost their jobs, some city people returned to villages, and anger grew against the rich business groups (zaibatsu) and against parties that seemed unable to help.

Rise of militarism

Militarism means that the army and its ideas get more power than elected leaders, and the country is run mainly for war. Here is how it grew in Japan:

Newspapers and schools were controlled, and speaking against the war could lead to arrest.

Second World War and its damage

In 1939 war began in Europe. In 1940 Japan joined Germany and Italy in a pact. On 8 December 1941 (Japan time) Japan attacked places in Hawaii and South-East Asia, and the Pacific War began. Japan took many lands across Asia, but from 1942 it began to lose. From 1944 bombers attacked Japanese cities. On 10 March 1945 a night raid burned much of eastern Tokyo. In April to June 1945 a long battle in Okinawa took the lives of many local civilians. In August 1945 atomic bombs fell on Hiroshima (6 August) and Nagasaki (9 August). On 15 August 1945 the war ended.

The human toll: in the whole world more than 70 million people died. About 3 million Japanese died. People in China, Korea, the Philippines and other Asian lands also suffered terribly, and in Europe about 6 million Jews were killed. Children were sent from cities to the countryside, food was rationed, and students worked in factories. After the war, many cities were rebuilt and many survivors worked for peace.

Try it: the four bars

Open the last 3D step and drag the year slider. Predict first: in 1931 which bar is highest? Then check. Next, move to 1941. Which bar has taken the place of Jobless as the main story? At home, ask an elder in your family what they know about hard times in their youth and write down two words they use.

Key formulas and definitions

Worked examples

1. How many years passed between the world crash of 1929 and the end of the war in 1945?

1945 - 1929 = 16 years.

2. Explain in two lines why the Depression helped the army gain support.

Many people lost jobs and income, and they were angry that parties and big business did not help. The army promised new land and resources abroad, so many people accepted its leadership.

3. Raw silk sold for 100 yen a bale in 1929 and for 40 yen in 1931. By what percent did the price fall?

The fall is 100 - 40 = 60 yen. 60 / 100 = 60 percent.
