Created in 2019, IWA (“the rock” in Japanese) is the publishing arm of Shibuya Productions.


Its first title, Blitz, is a shonen manga, exploring the elite world of chess.



With its chosen subject matter, Shibuya Productions attracted the attention of one of the greatest players of all time, Mr. Gary Kasparov, who now supervises and patrons the series.


Their common goal: to democratize chess by offering ambitious entertainment for all ages.

Blitz’s realization was made possible by the close collaboration between Monaco, Japan, the US and France, whose teams came together to produce a novel work guided by Japanese manga production techniques.


With the release of the first volume in the Blitz series, Cédric Biscay and Garry Kasparov immerse the reader into the fascinating universe of chess, where intuition and mental agility are precious assets on the way to victory.
