Shueisha Inc., the largest manga publisher in the world, has purchased an equity interest in Viz Communications, Inc. Viz was previously a wholly owned subsidiary of Shogakukan, another leading Japanese publisher. Shueisha's investment means that Viz is now linked to two of the top three manga publishers in Japan. The catalyst for Shueisha's foray into the American marketplace was the launch of the American version of Shonen Jump, Japan's leading manga anthology magazine, which is published by Shueisha. Shueisha, which with its 30% market share is the 'Marvel' of Japan, is not just providing some of the most popular Japanese manga series for the American Shonen Jump, it is also investing real money in the time-consuming and expensive marketing campaign for the magazine. Clearly Viz will need a major marketing push to meet its announced goal of a Shonen Jump U.S. circulation of 1 million copies per issue in three years.
