Tokyo prefecture spans not just the city, but rugged mountains to the west and subtropical islands to the south. The center of Tokyo, the former area reserved for the Shogun and his samurai lies within the loop, while the Edo-era downtown is to the extreme north and east. Sprawling around in all directions and blending seamlessly into Yokohama, Kawasaki and Chiba are Tokyo's suburbs. Over 400 years old, the city of Tokyo grew from the modest fishing village of Edo. The former seat of the Tokugawa Shogunate, the Imperial family moved to the city after the Meiji Restoration in 1868. The metropolitan center of the country, Tokyo is the destination for business, education, modern culture, and government. Worth to visit: Chiyoda, the seat of Japanese power that includes the Imperial Palace, the electronics mecca of Akihabara and the business center of Akasaka, Chuo, including the famed department stores of the Ginza and the fish markets of Tsukiji . Shibuya is the fashionable shopping district which also encompasses the teenybopper haven of Harajuku and the nightlife of Ebisu.  In Old Tokyo you can find Sumida by the river of the same name, including Ryogoku, home of the Edo-Tokyo Museum, Taito and Bunkyo, the heart of downtown Tokyo featuring the temples of Asakusa and many museums of Ueno. Koto, between the two rivers Sumida and Arakawa, located on just the south of Sumida.
