Change of era
- 1278 : The new era name was created to mark an event or a number of events. The previous era ended and a new one commenced in Kenji 4. The era name comes from the Veritable Records of the Emperor Taizong of Tang and combines the characters ("broad") and ("peaceful"). It should not be confused with the later Kōan era of 1361–62, which used a different character for kō (, "peace").
Events of the Kōan era
- August 15, 1281 (Kōan 4, 7th day of the intercalary 7th month)<!-- NengoCalc 弘安四年閏七月七日 -->: Battle of Kōan -- The second Mongol invasion of Japan is foiled, as a large typhoon – famously called a kamikaze, or divine wind – destroys much of the combined Chinese and Korean fleet and forces, numbering over 140,000 men and 4,000 ships.
- November 27, 1287 (Kōan 10, 21st day of the 10th month): In the 14th year of Go-Uda-tennōs reign (後宇多天皇14年), the emperor abdicated; and the succession (‘‘senso’’) was received by his cousin. Shortly thereafter, Emperor Fushimi is said to have acceded to the throne (‘‘sokui’’).
