What is The Silent Service: The Great Arctic Ocean Battle?

‘The Silent Service: The Great Arctic Ocean Battle’ is the latest live-action film in the series based on Kaiji Kawaguchi’s bestselling manga The Silent Service. As a continuation of the season released exclusively on Amazon Prime Video in 2023, ‘The Silent Service Season 1: The Battle of Tokyo Bay’, this new installment has been announced for theatrical release on September 26, 2025. This time, the conflict between Shiro Kaieda, the Japanese government, and the United States intensifies further, with a new strategic showdown set in the Arctic Ocean as the main highlight. The live-action version is produced by Amazon MGM Studios, with the stellar cast returning—led by Takao Osawa, joined again by Aya Ueto and Yosuke Eguchi. Not only fans of the original, but also newcomers can enjoy this entry, which is drawing attention as a high-quality Japanese military suspense film.

What’s the difference between the theatrical and streaming versions?

The Silent Service series has, at times, featured different edits or previously unseen scenes between its streaming and theatrical versions. For the previous title, The Silent Service Season 1, an eight-episode series—edited from the theatrical version’s footage—streamed exclusively on Amazon Prime. Given that, it’s highly likely this film will also stream exclusively on a subscription platform after its theatrical run.
