The heart-shaped "M" (Heart M) on our symbol mark stands for "Metro," the French word for subway. It reminds us that we serve the heart of Tokyo with thoughtful, heartfelt service. The background of the symbol mark is bright blue, our primary corporate color. This blue was chosen to convey an active, lively image in tune with the Tokyo Metro Group Ideal of "Keeping Tokyo on the Move."
We have combined the symbol mark and the "Tokyo Metro" name to create our communication mark which is displayed at points of contact with our customers, such as at station entrances, in train carriages, etc.
