In Japan we use the word “天の川(あまのがわ-amanogawa)” for the English word “Milky Way”. The “Milky Way” looks white like milk so in English you call our Galaxy “Milky Way”. Japanese ancient people named the Galaxy in same way. The first letter “天(てん-ten or あま-ama)” means “Sky” and the last letter “川(せん-sen or かわ-kawa)” means “river”, so the meaning of “天の川” is “a river of the sky”. From these two naming way to our Galaxy, I think the both of our ancient people had romantic thought to the sky.
