Tokyo, consistently rated one of the world's most expensive cities, has had a glaring absence of luxury hotels. Certainly, the Four Seasons is probably the best in town, but up till now it hasn't had any real competition. The Mandarin Oriental has just opened its 179 room hotel in Nihonbashi that balances the natural elements of forest and water. In other words, its designed to make you feel at one with nature, even though you are on top of a skyscraper is one of the most densely populated cities on Earth. Joining Four Seasons and Mandarin in 2007 are both Peninsula and Ritz-Carlton, who will open new hotels in Tokyo later in the year. The venerable Peninsula Hotel Group is opening a 315 room, 24 floor hotel in the Marunouchi district of Tokyo. Situated in a area experiencing a revitalization, the triangular shaped hotel will certainly become a hub of luxury-minded travelers. Ritz-Carlton is opening 250 rooms on the top nine floors of a high rise in Roppongi district. Part of a mixed-use facility designed by American architecture firm Skidmore, Owings & Merrill. The hotel will feature a sky lobby, several restaurants, and a large spa. At long last, a place to lay my head where I can dream of the world's most expensive hotel bill.
