Roppongi Hills welcomes visitors, but it also has four high-end residential complexes designed to accommodate 2,000 year-round occupants. A good number of those residents are sure to be the employees of large businesses like Goldman Sachs that have offices in Roppongi Hills. But for business travelers and luxury-minded tourists, Roppongi Hills has the Grand Hyatt Tokyo, one of Japan's most resplendent high-end hotels. In a city notorious for tiny living quarters and cramped hotel rooms, the Grand Hyatt stands dramatically apart. It is a place of soaring ceilings and a vast open lobby, a hotel that buzzes with activity while still managing to feel soothing and serene.

"Because everything in Tokyo tends to be so micro, our desire was to create a contrast," says architect Tony Chi. "It isn't common in Japan to encounter 145-foot-high ceilings in vast open places. Our thinking was, let's create awesome public spaces that are in line with Mr. Mori's vision to create a vibrant, modern place."

Its 390 rooms and suites are graced with finely appointed five-star detail: 300-thread-count sheets, flat-screen TVs, limestone baths, and rain showers. But the elegance doesn't end there. It extends throughout the hotel.

The Grand Hyatt has eight restaurants, and they offer a variety of cuisines, from contemporary Italian to Northern European to traditional Japanese. And there is a spa, of course. It's called Na­gomi, meaning "harmony," and is imbued with the Japanese sense of simple grace and refinement.

The hotel is linked by walkways to the Tokyo subway system, and it's just a short ride from attractions such as the famed Ginza district, the Kasumigaseki government area, and the Tsukiji fish market, a must-see for anyone looking for a unique slice of Tokyo life.
