Here's a track from the 1981 martial arts movie The Shinobi Ninja. Ken Suzuki, played by Tadashi Yamashita, is attacked by ninjas in a Tokyo bar. It begins just after the 45 minute mark in the movie.
Fortunately we can narrow things down a bit, as this movie turns out to have been scored with a bunch of '70s European library tracks. For example the theme of the movie is Janko Nilovic's "La Longue Marche." Most of the other tracks are from Italian composers like Ugo Busoni and Massimo Di Cicco. It was quite the surprise when I found out a few years ago that it wasn't scored by some Japanese musician, as some cuts sound like the music used in '70s Toei films.
