Tsuburaya served both as director and cinematographer of this feature-length national policy documentary, supported by the naval ministry, which creates a sketch of life among cadets aboard a naval training vessel on a voyage around Indochina, Malaya, Hawaii and the South Pacific islands. The film clearly outlines the economic motives behind Japan’s southward expansion, but also presents the music and dance traditions of various regions, in what has been termed “folklore through sound”.
