No, I have no idea why The Fifth Dimension’s “Aquarius / Let the Sun Shine In” is the musical accompaniment for a YouTube video on Japanese submarines. (You have to admit, it is stirring in its own way, though. Sort of.)
The video is approximately 16-17 years old, as the visible hull number on one of the submarines, 8005, is JDS Yaeshio, a Uzushio-class submarine converted in the mid-1990s to a training submarine.
For a more serious treatment of Japanese submarines, here’s a TV tour of Oyashio, lead ship in her class.
