BookWalker Adds Four Mahjong Pros Publishing Titles
Tuesday's additions include strategy guides, manga, and illustrated memoirs of Yuumi Uotani and Arisa Date.

BookWalker Global announced a partnership with Mahjong Pros Publishing on Tuesday and added four of the imprint's titles that day.
Kadokawa's BookWalker Global store announced Tuesday that it has partnered with Mahjong Pros Publishing, an imprint of mahjong set company Mahjong Pros. The retailer added four titles from the publisher that same day:
- Senba Kurono's 136 Ready-to-Use Mahjong Strategies and Tactics
- Hideki Ohwada's Reform with No Wasted Draws - The Legend of Koizumi, volumes 1–2
- Mio Junta and Suda Yoshiki's Crybaby Mermaid - Illustrated Memoir of Yuumi Uotani
- Ayato Sasakura's Vermilion Stella - Illustrated Memoir of Arisa Date, volume 1
BookWalker launched its rebuilt website, apps, and reader in March. They include the previously announced Lightweight Content Protection (LCP) DRM system, which lets users read purchases through compatible apps outside BookWalker.
All English-language manga and light novels transferred to the new BookWalker website and app. Japanese content will stay on the existing website and app.
In March 2025, ownership of BookWalker Global transferred from BookWalker Co., Ltd. to M12 Media LLC, formerly J-Novel Club LLC. Both BookWalker Co., Ltd. and J-Novel Club/M12 Media LLC belong to the Kadokawa Group.
Mahjong Pros announced its publishing imprint in June 2025. The imprint licenses, localizes, and distributes manga and textbooks focused on mahjong.
