If you have 5 days to spend in Tokyo, then I would suggest spending on of those days visiting Nikko. Two hours north of Tokyo taking the Shinkansen and JR Nikko line which includes a transfer at Utsunomiya. It's easy to get to and if you are lost, just ask the station staff who will be happy to guide you to the right train and track.
I had seen photos of Nikko in the past and they looked impressive and wanted to get some of my own. Nikko is famous for the Nikko Toshogu Shrine and from the photos it looked stunning.
On my visit it was raining all day but that didn’t deter me nor the other visitors who were there, so remember to be prepared and bring waterproofs or at least an umbrella as it was non-stop rain when I was there. It actually added to the atmosphere and made it feel like being in ancient Japan.
