Media Do International to Acquire Seven Seas Entertainment

(March 1, 2026) – Media Do International, Inc., part of the MEDIA DO Group, has entered into a definitive agreement to acquire Seven Seas Entertainment, Inc., the largest independently owned manga publisher in the English-language market and one of North America's leading publishers of manga, light novels, webtoons, and danmei.

Founded in 2004 by Jason DeAngelis, Seven Seas has played a central role in the growth of manga and light novels in the English-language market. Over more than two decades, the company has licensed and published over 1,300 series and thousands of titles from Japan, China, South Korea, and beyond. Known for its pioneering spirit, bold publishing choices, thoughtful curation, and strong editorial standards, Seven Seas has built enduring relationships with creators, licensors, retailers, and readers.

The acquisition reflects continued global momentum in manga, light novels, and international storytelling across print, digital, and audio formats, and positions Seven Seas for long-term growth within an expanding worldwide readership.

Seven Seas will continue to operate under its existing leadership team and editorial direction. There are no changes to distribution, publishing schedules, or core operations as a result of this transaction. All Seven Seas print imprints will continue to be distributed worldwide by Penguin Random House Publisher Services.

“For more than twenty years, our focus has been simple: publishing exceptional stories and treating them with care, respect, and the passion of fans who never forget what drew us to these stories in the first place,” says Seven Seas CEO and founder Jason DeAngelis. “This partnership strengthens our long-term position while preserving the creative independence and publishing mission that define Seven Seas. We remain deeply committed to our creators, partners, and readers.”

“Seven Seas has built a distinctive and highly respected publishing program, with a strong track record and deep connections across the industry,” says Daihei Shiohama, President and CEO of Media Do International. “We look forward to supporting their continued success and providing resources that allow the Seven Seas team to do what they do best—champion great stories for readers around the world.”

The companies will collaborate to further strengthen global distribution and support the continued growth of Japanese, Chinese, and Korean storytelling in the English-language market.
