Seven Seas Entertainment

Seven Seas Entertainment is an award-winning American publisher that publishes and translates into English Japanese manga, light novels, Chinese danmei and manhua, as well as original English-language manga.

Seven Seas was founded in 2004 by Jason DeAngelis. Originally, it only published "world manga," a synonym for original English-language manga coined by DeAngelis.

In 2017, Seven Seas entered into a partnership with J-Novel Club to release print editions of some of their titles.

In 2018, Seven Seas won the Harvey Award for Best Manga for its English version of My Lesbian Experience With Loneliness.

On November 20, 2020, Seven Seas announced that it would be switching distributors worldwide, with all imprints moving to Penguin Random House starting on July 1, 2021.

In early 2021, it was found by fans on Reddit that Seven Seas had been making alterations to their English translations of certain light novels, namely Classroom of the Elite, Mushoku Tensei: Jobless Reincarnation, and I'm in Love with the Villainess. This was seen by fans as intentional censorship due to the fact some of the material removed or altered was controversial. The original authors were not consulted nor were the translators made aware of the changes until after the fact. Seven Seas announced that they would be revising these changes, republishing the affected volumes, and making changes to their editing process.

On May 23, 2022, employees of Seven Seas formed a union called "United Workers of the Seven Seas." A week later, Seven Seas management announced they would not recognize the union and had a brought a case against them with the NLRB. On June 24, 2022, the United Workers of the Seven Seas announced that Seven Seas had agreed to voluntarily recognize the union.

On March 1, 2026, it was announced Seven Seas was wholly acquired by Media Do International, part of the Media Do Group, Japan's largest ebook distributor.
