[Note:  The longstanding (circa 1919) pre-World War II, government managed, “Teiten” (Japan Imperial Art Academy) was reorganized into an independent private corporation called “Shin-Nitten” in 1946.  Nitten was again reorganized in 1958 and was reformed into its present expanded structure, “Kaiso-Nitten,” in 1969, developing into the largest and most prestigious national combined arts exhibition of its kind in the world.  Nitten is organized into five departments:  Japanese Style Painting, Western Style Painting, Sculpture, Art Crafts, and Calligraphy.  The great masters of the Modern Japanese Art World are encouraged, developed, and featured along side the new generations of artists in Nitten sponsored exhibitions across Japan.  A screening board decides which art works among thousands submitted are honored with acceptance as official exhibits at the annual Nitten exhibitions.  A panel of judges on the Nitten Selection Committee selects a special group of the higher quality exhibits deserving of the “Tokusen” (Special Commendation Citation).  The judges chose the very best of these candidates to receive honorable recognition as “Hakuju” (Superior Achievement Award) winners.  The judges then identify the top performing artists in each department to receive the highest Nitten honor bestowed upon an artist’s exhibit, the Japanese Prime Minister’s Award.]
