@@楽太郎-j7z yes, though Dravidian people is hypothetical. Japan and Tamil are close and possibly from same root. Bodhi Dharma (Daruma San) is Tamil. Japan and South India were connected by sea trade, so there has been cultural exchanges for a long time. There are both tamil & sanskrit words in Japanese. Go look it up. Japanese style pointy roof top buildings are found in South India even today. Especially in Kerala, the construction is very similar.
