Jump Square

Newsstands across Japan received the first issue of Jump Square on November 2, 2007, carrying a December 2007 date stamp. Shueisha launched this monthly magazine to replace Monthly Shōnen Jump, which had ceased publication just five months earlier after decades of operation. The debut run included 500,000 copies, and readers bought over 70 percent of them within three days. Tokyo retailers specifically moved 90 percent of their stock in that same window.

Kosuke Yahagi assumed the role of editor-in-chief in 2015 and steered the publication toward stories with darker tones and more mature themes. This editorial shift attracted a demographic of males aged 15 to 34 seeking complex emotional arcs alongside traditional action. Circulation figures reflect industry-wide trends; the magazine dropped from roughly 140,000 copies in 2021 to 90,667 copies during the October–December 2025 period.

The lineup features Kazue Kato's Blue Exorcist, which began serialization in April 2009 and remains the longest-running hit. Other major series include Kono Oto Tomare! Sounds of Life since 2012, Kemono Jihen since 2016, and Dark Gathering since 2019. Nobuhiro Watsuki returned with Rurouni Kenshin: The Hokkaido Arc in 2017, while World Trigger migrated from Weekly Shōnen Jump later that year. A quarterly spin-off called Jump SQ.19 launched on May 19, 2010, to host one-shots before newer digital content shifted to Jump SQ. Rise. [编辑]
