About Nihon Sankoku
Nihon Sankoku is a manga by Matsuki Ikka, serialized on Shogakukan’s comic app “Manga One” and the web comic site “Ura Sunday.” Set in a near-future Japan where civilization has collapsed in the wake of nuclear war, natural disasters, and corrupt governance, the story follows a revolution that splits the country into three rival kingdoms. Amid this era of division, a minor local bureaucrat named Sankaku Seiki rises through the ranks using his vast knowledge and sharp tongue, driven by a dream of reunifying Japan.
