Emperor Taisho, born on August 31, 1879, was the 123rd emperor of Japan, reigning from 1912 until his death in 1926. His reign is often referred to as the Taisho Era, a period marked by significant political and social changes in Japan, including the rise of democracy and modernization. During his rule, Emperor Taisho faced health issues that limited his public appearances, leading to his son, Crown Prince Hirohito, taking on many responsibilities. The era saw Japan's involvement in World War I and the signing of the Treaty of Versailles, which established Japan as a significant global power.
