Despite its business district location (convenient!), the brand-spanking new spot feels nothing like a business hotel. Modern Japanese sensibilities bring a coziness to both the private rooms and public spaces, like the lobby area that doubles as a communal tea-drinking space, the lovely contemporary gallery, and the indoor/outdoor rooftop bar. Wake up in a comfy yukata and visit the spa on the 37th floor for panoramic views of the Imperial Palace and central Tokyo.
