The National Sports Festival is the premier prefecture versus prefecture sports event in Japan. The abbreviated name is Kokutai which literally translates into ‘National Polity’ or ‘Fundamental Character of the Nation.’
Winners in each discipline are awarded the Emperor or Empress Cup.
The first Kokutai was held in 1946 with the cities of Osaka, Kyoto, and Kobe being co-hosts.
Since then, the national sports festival has been held on an annual basis without interruption.
The last three Kokutai meets 64/65/66 were hosted by Niigata, Chiba, and Yamaguchi prefectures.
Yamaguchi Prefecture is hosting the event for the second time after 1965.
