The official website for the live-action adaptation project of The Silent Service, based on Kaiji Kawaguchi’s political-military manga, released a teaser trailer and visual for its second theatrical film today, subtitled “Hokkyokukai Daikaisen” (translated to “The Great Sea Battle of The Arctic Ocean”).
The trailer shows the nuclear submarine Yamato sailing in the Arctic Ocean, and the general House of Representatives election beginning in Japan. Shiro Kaieda, the captain of Yamato played by Takao Osawa, murmurs with cold eyes, “Wake up.” at the end.
The tagline on the visual reads “There is no retreat. Find a way out.”
Eight cast members from the first film are additionally confirmed to reprise their roles:
Hiromi Ichitani (newscaster) played by Aya Ueto
Eiji Yamanaka (the Deputy Captain of Yamaro) played by Aoi Nakamura
Toshio Takegami (Prime Minister of Japan) played by Takshi Sasano
Hitomi Sonezaki (Minister of Defense) played by Yui Natsukawa
Seiji Kageyama (Minister of Foreign Affairs) played by Yoshi Sako
Wataru Kaibara (Chief Cabinet Secretary) played by Yosuke Eguchi
Takuo Minaguchi (sonarman of Yamato) played by Ko Maehara
Satoshi Irie (IC member of Yamato) played by Kodai Matsuoka
Kawaguchi’s original manga was serialized in Kodansha’s Weekly Morning magazine from 1988 to 1996, then compiled in 32 tankobon volumes with a total circulation of 32 million copies (paper and digital).
As Amazon Studios’ first Japanese theatrical film, the first live-action project’s feature film released in Japan on September 29, 2023, earning 1.37 billion yen (9.02 million USD) from its total domestic run. The eight-episode web drama series, The Silent Service Season One – The Battle of Tokyo Bay, followed on Amazon Prime Video in February 2024.
The sequel film focuses on the “Great Sea Battle of the Arctic Ocean” and the “Yamato Election” episode, which was made into a TV special at the time of the original manga’s serialization in Japan.
Theatrical screenings for the second film are scheduled to begin on September 26, 2025 in Japan.
The synopsis reads (translated):
Yamato submerges in the cold, deep northern seas with Mozart’s music echoing. The nuclear-powered submarine, named the “Great and Powerful Peace,” overwhelmed the U.S. Seventh Fleet in the Battle of Tokyo Bay and set course for New York. As it approached the Bering Strait, the border between the U.S. and Russia, a submarine loomed behind Yamato…
“Sink the nuclear terrorist Yamato!” It is a cutting-edge U.S. submarine, far superior to Yamato, sent by the U.S. President Bennett.
At the same time, a general election is held in Japan to dissolve the House of Representatives. Prime Minister Takegami announces his support for Yamato, and the two will share the same fate, whether they remain or sink.
Will Shiro Kaieda be able to overcome the greatest challenge of the voyage? Under the aurora borealis, in the Arctic Ocean with floating ice floes, the curtain rises on the battle to be fought.
