Japanese has different ways to refer to the Milky Way depending on whether you are speaking scientifically or poetically. 銀河系 is the standard scientific term used to describe our galaxy. The term 天の川 (amanogawa) is used to describe the appearance of the band of light in the night sky, often in a more descriptive or literary sense. By combining these ideas, you can use 天の川銀河 to specifically refer to the Milky Way galaxy.
