Our 6-hour layover tour was with Tony, a private guide, it was great. Tony took us to major sites such as Asakusa Temple, Tokyo Skytree, Ginza, and Shibuya Crossing. He was very knowledgeable about every site and Tokyo in general. We also had an authentic ramen dinner. He also took many pictures of us at the sites as well. Highly recommended!
