In Japan, the train lines are generally named after the end stations in a way that is uniquely Japanese - by combining the first (or sometimes second) Chinese characters of the names of these stations. However, because the reading of the characters commonly changes when used separately, the names will often make no sense for non-Japanese speakers. For example, the line running from the north part of Tokyo (東京) to Yokohama (横浜) is called the Keihin-Tōhoku Line (京浜東北線), where Tōhoku means north-east. Knowing this, I can't help but wonder what the end station for the Utsunomiya Line (宇都宮線) is, since Uchū (宇宙) is the Japanese word for outer space...
