From the authors of "Shin Angyo Onshi" a new manga set in Japan and Korea during the Edo period, a time of great upheaval between the two cultural groups. In ancient times, Japan and Korea would send its criminals to a penal colony called "Kyokudo", situated in the channel between the two nations. There the cannibal Juu was sent for murdering over a thousand warriors while in Edo. Yet for an island meant for criminals, there was but one Korean medic, Han, exiled from Korea for killing and dissecting over a thousand people.

Osamu Tezuka’s vaunted storytelling genius, consummate skill at visual expression, and warm humanity blossom fully in his epic of Siddhartha’s life and times. Tezuka evidences his profound grasp of the subject by contextualizing the Buddha’s ideas; the emphasis is on movement, action, emotion, and conflict as the prince Siddhartha runs away from home, travels across India, and questions Hindu practices such as ascetic self-mutilation and caste oppression. Rather than recommend resignation and impassivity, Tezuka’s Buddha predicates enlightenment upon recognizing the interconnectedness of life, having compassion for the suffering, and ordering one’s life sensibly. Philosophical segments are threaded into interpersonal situations with ground-breaking visual dynamism by an artist who makes sure never to lose his readers’ attention.
Tezuka himself was a humanist rather than a Buddhist, and his magnum opus is not an attempt at propaganda. Hermann Hesse’s novel or Bertolucci’s film is comparable in this regard; in fact, Tezuka’s approach is slightly irreverent in that it incorporates something that Western commentators often eschew, namely, humor.

Note: Won the Bungei Shunju Manga Award in 1975 and the Best U.S. Edition of International Material for the Eisner Award in 2004 and 2005.
