Ginza in Tokyo is filled with lights - lights from the street, lights from the cars, and lights from all the fancy retail stores. One thing very common in Tokyo during rainy days is the umbrella - clear color umbrella - almost everyone is using it, and every convenient story is selling it. Doesn't matter how crowded the street is, how dark the night is, you can always see you way clearly. If my suitcase had room, I would get one and bring home.
