However, in the autumn of 1949, a publishing panic known as the "Mountain of Returns" occurred, and Shobunkan, unable to withstand this turmoil, transferred its debts and assets, establishing the new company, Houbunsha, on July 10, 1950.

Although once hailed as the king of boys' magazines, "Yakyū shōnen" continued to decline due to the increasing influence of mass media such as sports newspapers and television.

As manga diversified further and integrated into readers' daily lives, the market expanded to a scale of trillion of yen, including anime, character goods, and game software, growing into a mass production industry literally.

With the widespread of personal computers and mobile phones, traditional reading styles underwent significant changes, leading to a continued decline in overall sales in the publishing industry.

Taking these trends into account, especially the accelerating digitization of the publishing industry, they established the cross-media business division in 2007, aiming to flexibly respond to organizational changes and expand into overseas markets, integrating new cultures and media to continue creating content beloved by many readers.
