The Twelve Kingdoms (Japanese: 十二国記, Hepburn: Jūni Kokuki, also known as "Record of 12 Countries" or "Jūni Kokki," a common alternate reading) is a Japanese series of light novels written by Fuyumi Ono and illustrated by Akihiro Yamada. The first entry in the series ("The Shadow of the Moon, The Sea of Shadow") was published by Kodansha in Japan in 1992; the last Kodansha volume was released in 2001. In 2012 the series was resumed under the Shinchō Bunko line from Shinchosha. Shinchosha has also begun reprinting the older volumes with new cover and interior art from Akihiro Yamada. The Chinese mythology-influenced books were adapted into an animated television series in 2002. The Studio Pierrot production aired on Japan's NHK from April 9, 2002 to August 30, 2003, totaling 45 episodes. The novels were licensed in the United States by Tokyopop and the first four volumes were released between March 2007 and November 2010 as part of their Pop Fiction line. Subsequently, the English license reverted to Kodansha. The entire anime series has been released on DVD and Blu-ray in the United States by Media Blasters.
