Akira Kurosawa's Seven Samurai (1954) is a three-and-a half-hour-long black-and-white epic set in war-torn, 16th-Century Japan. As elevator pitches go, it’s hardly ideal, yet not only did Seven Samurai take first place in BBC Culture’s 100 greatest foreign-language film poll, with 41 critics (20 per cent of the total) voting for it, Kurosawa was one of the most popular directors overall, with three of his other films (Rashomon, Ikiru and Ran) all making the top 100. Tellingly, though, Kurosawa’s global appeal didn’t reach as far as the Japanese critics who took part; not one of them voted for Seven Samurai, or any other Kurosawa film, preferring the subtler homegrown talents of Yasujirô Ozu and Kenji Mizoguchi. But perhaps that’s what we should have expected. Even during his most successful film-making years, Kurosawa was often held in higher esteem abroad than in his own country.

To begin with, he was the first Japanese director to win international acclaim when his film Rashomon was awarded the Golden Lion at the 1951 Venice Film Festival. And Seven Samurai surely owes part of its popularity in the West to the fact that, in the pre-video era, it was one of the first Japanese films many viewers had ever seen. It introduced a culture that was foreign yet intriguing, and accessible to audiences weaned on Hollywood westerns. In later years, Kurosawa tended to downplay his enthusiasm for the films of John Ford, but his achievement was to combine the conventions of the western with a radical new fusion of Japanese genres: the chambara (swordplay film) and the jidaigeki (period drama).
