Emperor Seimu

Mausoleum of Emperor Seimu near Heijô-kyô

• Reign: 131-191
• Japanese: 成務天皇 (Seimu tennou)

Emperor Seimu is an early emperor described in the Kojiki; he is considered the 13th Emperor of Japan by the "traditional" counting. It is unclear whether he was a historical figure, or should be regarded as more purely legendary.

According to the Kojiki, it was during the reign of Emperor Seimu that the borders were determined, and the land developed.

A kofun northwest of the Heijô Imperial Palace is traditionally identified as his mausoleum. It neighbors those of Empress Kôken and Hibasuhime no mikoto, consort to Emperor Suinin.
