Cross the Tokyo Bay Aqua-Line to ditch the city noise for sea views and retail therapy. Walk the massive Nakanoshima Red Bridge for a view of the skyline, then hit Mitsui Outlet Park for better deals than Ginza. If you have a full day, take the Kamakura Cherry Blossom Walking Tour with a local to see the flowers without the crowds. It is the best day trip you aren't taking yet.
