Media Do Acquires Seven Seas Entertainment for $80 Million

The biggest publishing industry deal to break in the last 24 hours is the acquisition of Seven Seas Entertainment — the largest independently owned manga publisher in the English-language market — by Media Do International, the San Diego-based subsidiary of Tokyo's MEDIA DO Group, Japan's largest e-book distribution company. The purchase price is reported at $80 million USD (approximately ¥12.4 billion JPY), with the announcement made in the early hours of March 2, 2026 (5:00AM JST). Seven Seas, founded in 2004 by Jason DeAngelis, has licensed and published over 1,300 series and thousands of titles from Japan, China, South Korea, and beyond, spanning manga, light novels, webtoons, danmei, and audiobooks. All Seven Seas print imprints are distributed worldwide by Penguin Random House Publisher Services. The deal carries significant implications for digital publishing. Media Do already owns Firebrand Technologies, NetGalley, and Supadü — giving it a powerful stack of publisher-facing technology and marketing infrastructure. The acquisition of Seven Seas adds a high-volume English-language content operation to that ecosystem. According to reporting by Danmei News, a Nikkei article published alongside the official press release states that Media Do plans to use its own AI to assist translators, reducing manga translation time from the current five to six months per volume to approximately two months, and to increase Seven Seas' annual output from around 1,000 titles to approximately 2,000 titles per year. The official Seven Seas press release does not address the AI translation plans, and the company has not publicly responded to questions about the Nikkei report. The deal is notable for the broader publishing industry as a signal of continued consolidation in the digital and manga publishing space, and for the explicit role AI-assisted translation is expected to play in scaling output post-acquisition. ---
