September 20 — Japan’s History and Today

September 19, 2026

September 20 marks important historical events in Japan. In 1336, Emperor Komyo of the Northern Court ascended to the throne, deepening the split between the Northern and Southern Courts. Also, in 1498, the Meio Earthquake caused a tsunami that washed away the Great Buddha Hall of Kamakura, a notable natural disaster in Japanese history.

In 1336 (the first year of Engen era / the 3rd year of Kenmu), Emperor Komyo of the Northern Court took the throne, intensifying the divided reign known as the Northern and Southern Courts period. This political split was a critical episode in medieval Japanese history, affecting the cultural and warrior class structures of the time. Understanding this period helps grasp the complexities of Japan’s historical governance.

On September 20, 1498 (the 7th year of Meio), the Meio Earthquake struck, triggering a massive tsunami that swept away Kamakura's Great Buddha Hall. Japan is prone to earthquakes and tsunamis, and such events have shaped disaster preparedness culture today. For foreign residents and visitors in Japan, learning about earthquake and tsunami safety, including evacuation routes and emergency contacts, is essential.
