The New Otani boasts one of the city's best hotel gardens, more than 400 years old and once the private estate of a feudal lord. Spreading over 4 hectares (10 acres), it contains ponds filled with koi, waterfalls, arched bridges, manicured bushes (the many azaleas are especially striking in spring), stone lanterns, bamboo groves, and a stone garden. The large outdoor pool, shrouded by greenery, provides more privacy than most hotel pools and is free for members of Otani Club International (membership is free). That's about it, however, when it comes to communing with nature, as this is one of Tokyo's largest hotels (be sure to pick up hotel and garden maps at the concierge, because you're going to need them). Its 31 restaurants and 6 bars draw huge crowds of locals, especially its very popular Garden Lounge offering the best views of the garden and The Sky revolving restaurant. Rooms are spread among the main building, built for the 1964 Olympics and offering the best up-close views of the garden, and the 40-story Garden Tower with views over the glittering city. Because rates are the same regardless of view, ask for a room facing the garden. Hotel facilities are so exhaustive this is like a city within a city; folks who shun crowds will be happier elsewhere.
