What does the Japanese tram route map on Google Maps represent?

Japanese railways are divided into JR and private railways, each with its own logo. Therefore, on the map of Japan, the black and white grid lines generally represent the JR line, and the sign is JR and written together. Other companies use their own signs to mark their railway lines, which are represented by thin black lines.

On Google Maps, the thin black line represents the ground wire, and the blue sign in front represents the power station on the ground, which can be used by any company. The dotted red line with the sign represents the subway.

If you see a station marked with a blue front, it means that there is a tram and subway transfer at this station, and you can get off the tram and transfer to the subway here.

The green ginkgo biloba leaves are the symbol of Tokyo Transportation Bureau, and the blue square formed by two and a half ellipses is the symbol of Tokyo Metro.

Because the Tokyo Metropolitan Transportation Bureau has four subway lines (Edo Line, Asakusa Line, Shinjuku Line and Tamami Line), you can see the Ginkgo logo of the Tokyo Metropolitan Transportation Bureau on the map of Tokyo, which is one of those four subways.

Circle+Bar is the city subway of Osaka Transportation Bureau.
