I would like to introduce you the Panda Bus (パンダバス).
If you plan to visit Asakusa (浅草) and don't want to walk a lot, I suggest you to use either the girl or boy Panda bus.
Why ? Because it is FREE and cute at the same time. When you get on, all seats are their own ears.
I think you will appreciate to have a good overview of Asakusa and (around) as well as a good mean to reach Tokyo Sky tree.

So to find this bus you need to reach "Asakusa Tsukuba Express station" in front of the Sensoji temple (浅草寺) or go to the ROX building (see picture 3), which is the initial stop. All Panda bus stops have an icon where it is marked Asakusa Pandabus in japanese.

Check out the official website (only in Japanese) to discover the schedule time and the map.
If you need help in japanese, let me know and I will help you to figure it out.
