If you have a certain sort of love for big cities, you're bound to love Shinjuku. Come here, and for the first time Tokyo begins to seem real: all the celebrated virtues of Japanese society—its safety and order, its grace and beauty, its cleanliness and civility—fray at the edges.
To be fair, the area has been on the fringes of respectability for centuries. When Ieyasu, the first Tokugawa shogun, made Edo his capital,
Shinjuku was at the junction of two important arteries leading into the city from the west. It became a thriving post station, where travelers would rest and refresh themselves for the last leg of their journey; the appeal of this suburban pit stop was its "teahouses," where the waitresses dispensed a good bit more than sympathy with the tea.
When the Tokugawa dynasty collapsed in 1868, 16-year-old Emperor Meiji moved his capital to Edo, renaming it Tokyo, and modern Shinjuku became the railhead connecting it to Japan's western provinces. It became a haunt for artists, writers, and students; in the 1930s Shinjuku was Tokyo's bohemian quarter. The area was virtually leveled during the firebombings of 1945—a blank slate on which developers could write, as Tokyo surged west after the war.
After the Great Kanto Earthquake of 1923, Nishi-Shinjuku was virtually the only part of Tokyo left standing; the whims of nature had given this one small area a gift of better bedrock. That priceless geological stability remained largely unexploited until the late 1960s, when technological advances in engineering gave architects the freedom to soar. Some 20 skyscrapers have been built here since then, including the Tokyo Metropolitan Government Office complex, and Nishi-Shinjuku has become Tokyo's 21st-century administrative center.
Now, by day the east side of Shinjuku Station is an astonishing concentration of retail stores, vertical malls, and discounters of every stripe and description. By night much of the activity shifts to the nearby red-light quarter of Kabuki-cho, which is an equally astonishing collection of bars and clubs, strip joints, hole-in-the-wall restaurants, pachinko parlors (an upright pinball game), and peep shows—just about anything that amuses, arouses, alters, or intoxicates is for sale. Recent crackdowns by police have limited this sort of adult activity but whatever you’re after is probably still there if you know where to look.
