Japan's cities may look Westernized -- often disappointingly so -- but beyond first impressions there's very little about this Asian nation that could lull you into thinking you're in the West. Yet Japan also differs greatly from its Asian neighbors. Although it borrowed much from China in its early development, including Buddhism and its writing system, the island nation remained steadfastly isolated from the rest of the world throughout much of its history, usually deliberately so. Until World War II, it had never been successfully invaded; and for more than 200 years, while the West was stirring with the awakenings of democracy and industrialism, Japan completely closed its doors to the outside world and remained a tightly structured feudalistic society with almost no outside influence.

It's been just a little more than 136 years since the Japanese opened their doors, embracing Western products wholeheartedly, yet at the same time altering them and making them unquestionably their own. Thus, that modern high-rise may look Western, but it may contain a rustic-looking restaurant with open charcoal grills, corporate offices, a pachinko parlor, a high-tech bar with views of Mount Fuji, a McDonald's, an acupuncture clinic, a computer showroom, and a rooftop shrine. Your pizza may come with octopus and beer gardens are likely to be fitted with Astroturf. City police patrol on bicycles, garbage collectors attack their job with the vigor of a well-trained army, and white-gloved elevator operators, working in some of the world's swankiest department stores, bow and thank you as you exit.

Because of this unique synthesis of East and West into a culture that is distinctly Japanese, Japan is not easy for Westerners to comprehend. Discovering it is like peeling an onion -- you uncover one layer only to discover more layers underneath. Thus, no matter how long you stay in Japan, you never stop learning something new about it.
