The city of Kyoto consists of a square grid of streets running north-south and east-west around the Kamo river. A large number of temples and historical sites are located in the city. In addition to being a significant tourist magnet, attracting every year a large number of visitors, Kyoto is also a regional industrial centre for IT and electronics: several Japanese multinationals are headquartered here. Kyoto's historic district of Gion originated in the middle ages to accommodate travelers and visitors to the Yasaka shrine. Over time it became one of the most exclusive and well-known geisha districts in Japan.
