Kōan (Kamakura period) facts for kids

The Kōan (error: {{nihongo}}: Japanese or romaji text required (help)) was a special way of counting years in Japan long ago. It was like a time period or an 'era name' (called nengō in Japanese). The Kōan era came after the Kenji era and before the Shōō era. It lasted for about ten years, from February 1278 to April 1288. During this time, two emperors ruled Japan: Emperor Go-Uda and Emperor Fushimi.

Key Events During Kōan

The Mongol Invasion Attempt (1281)

One of the most important events during the Kōan era happened in 1281. This was the second time that powerful Mongol forces tried to invade Japan. This big conflict is known as the Kōan War (or Kōan no Eki).

The Mongols, led by Kublai Khan, had already tried to invade Japan once before. This second attempt was even larger. They sent a massive fleet of ships and many soldiers. However, the Japanese warriors fought bravely to defend their homeland.

Luckily for Japan, a powerful typhoon, often called a "divine wind" or Kamikaze, struck the Mongol fleet. This storm destroyed many of their ships and forced the invaders to retreat. This event saved Japan from being conquered.

Emperor Go-Uda Steps Down (1287)

In 1287 (which was the 10th year of the Kōan era), something important happened with the emperor. Emperor Go-Uda decided to step down from his role. This means he gave up his position as emperor.

After Emperor Go-Uda stepped down, his cousin became the new emperor. This was a common practice in ancient Japan, where emperors sometimes chose to retire and let someone else take the throne.
