サブマリン７０７ [Submarine 707]

In the mid-1960s, creator 小沢さとる launched this six-issue manga series for 秋田書店, a taut naval thriller centered on the crew of a cutting-edge submarine. The story pits the titular 707 and its commander against a shadowy undersea threat, blending Cold War-era tension with detailed, mechanical artistry. Though brief in its original run, the series has endured since 1967 as a cult touchstone for fans of Japanese military adventure comics.
