Ancient Link Between Japanese and African People? (Old, Outdated, No Sources)

Disclaimer, this is a very old video where I was less experienced at video research and editing. Its not an attempt to discredit or steal from the rich history of the Japanese people. It is simply an old video where I noticed some similarities in the language and some cultural aspects of the Japanese and the various vibrant cultures of Africa. PS: I know that the statue in the thumbnail (also featured in the video) is Chinese. Honest mistake.
