Japan

Flags through time 🎏

A flag is a country telling you what it believes. Scroll the timeline and watch Japan change.

1600s–1868

Tokugawa era banners

Japan was run by shoguns (military rulers). Each clan flew its own crest banner instead of one national flag.

1870–1945

Rising Sun naval ensign

When Japan modernised, the sun disc with rays became the navy's flag during a time of empire and war.

1870–today

Nisshōki β€” the sun disc

The simple red circle on white means 'origin of the sun'. It became the official national flag by law in 1999.

War room simulations βš”οΈ

Step into the room where the decision was made. You will see who really had the power β€” generals, a president, a parliament or a king β€” and what each choice cost.

1941–1945
Decided by: Military generals and admirals

The Pacific War (part of World War II)

Japan's military leaders expanded across Asia and the Pacific. The war ended after enormous destruction, including the atomic bombings of Hiroshima and Nagasaki.

Who was in the room? In the 1930s the army and navy had more power than the elected Diet, so a small group of officers made the biggest choices.

Policies today πŸ“‹

Environment

Aiming for net-zero carbon by 2050

Japan wants to stop adding extra greenhouse gases to the air by 2050. It is building more solar farms and restarting some nuclear plants to burn less coal and gas.

Population

Paying families to help with children

Fewer babies are being born, so the government gives money and free childcare to families to make raising kids easier.

Technology

Robots and AI in daily life

Japan funds robots that help nurses and farmers because there are not enough workers for every job.
