Swim on the 29th floor of the Shangri-La hotel Tokyo 

if you want a swim with a magnificent views then the pool at the Shangri-La Hotel Tokyo is hard to beat. At night then the view is magical overlooking the lights of the city. The water is warm and at the times we swam quiet. There is also a jacuzzi area in the male and female changing areas. At the side of the pool you will find comfortable loungers with fresh lemoned water. You can also have a work out in the small gym as you enter the pool area.
