What is "The Twelve Kingdoms"?

"Tsuki no Kage Kage no Umi (Part 1) The Twelve Kingdoms" by Fuyumi Ono, "Tsuki no Kage Kage no Umi (Part 2) The Twelve Kingdoms" by Fuyumi Ono.

Fuyumi Ono's representative work, read continuously since 1991. A grand story that shocked the Japanese fantasy world!

It is a magnificent fantasy set in our world and another world that does not exist on Earth. The two worlds are separated by a vast sea called the Kyokai and are connected only by a phenomenon called "Shoku." In the other world, twelve kingdoms—Kei, Sou, Han, Ryu, Kan, Kyou, Sai, Kou, Tai, Shun, Hou, Ren—surround the Yellow Sea, which is home to the five mountains where gods reside, in a geometric pattern. In each kingdom, a "Kirin," a divine beast that has received the will of heaven, finds a king and places them on the throne through a "covenant." The king has eternal life as long as they have the mandate of heaven, ruling the country, and the Kirin serves by their side as prime minister. The profound human dramas unfolded in each kingdom can be called an epic novel that asks us about "the meaning of life" and "the strength to believe." It also gained attention when it was adapted into an NHK anime (2002-2003).

In December 2025, the musical "The Twelve Kingdoms" starring Hikaru Yuzuka garnered a huge response and is once again attracting attention.
