How was The Twelve Kingdoms anime made?
A public broadcaster’s prestige slot, a studio known for long runners, and the novels’ own painter setting the look.
The anime of The Twelve Kingdoms ran on NHK’s BS2 satellite channel from April 9, 2002 to August 30, 2003, forty-five episodes animated by Studio Pierrot and directed by Tsuneo Kobayashi. It was an unusual commission for its moment: a slow, political fantasy novel sequence, adapted at novel pace, for Japan’s public broadcaster.
Two choices define its feel. The scripts were written by Shō Aikawa for episodes 1 to 40 and Seiya Fujima for the final stretch, treating each novel as a sequence of titled "chapters" rather than self-contained episodes. And the look descends directly from the books: Yamada is credited with the character-design draft, so the anime’s faces are his paintings, simplified for motion.
THE PRODUCTION
Pierrot and NHK, 2002THE COMMISSION
NHK BS2 was the broadcaster’s satellite home for prestige animation. Forty-five episodes across sixteen months is a long runway by modern standards, and the show uses it: councils, journeys, and sieges get the episodes they need.
THE MUSIC
Kunihiko Ryo composed the score, including the opening "Jūnigenmukyoku," an instrumental theme at a time when anime openings were j-pop singles. The ending, "Getsumei Fūei," is sung by Mika Arisaka. Strings and melancholy, in keeping with the source.
THE DESIGNS
Yamada’s credit is "character design draft": the production designs are adaptations of his novel illustrations, which is why the anime remains, visually, a member of the same edition family as the books.
