Manga about mathematician Shunkai Shibukawa launched in 2011

The December issue of Kodansha's Afternoon magazine published the final chapter of Ebishi Maki's manga adaptation of Tow Ubukata's Tenchi Meisatsu novel on Saturday. In addition, the magazine notes that Kodansha will publish the manga's ninth and final compiled book volume on December 22.

In Ubukata's original novel, the real-life Edo-era mathematician Shunkai Shibukawa pursues a project that alters his life as much as it alters Japanese culture — the creation of Japan's own lunar calendar system.
