The Senso-ji Temple is Tokyo's oldest shrine dating back over 1000 years, before Tokyo, or even Edo were thought of. Like most Japanese temples it has been rebuilt many, many times, but it is still a draw card for tourists and Toykoites alike.
The crowds, the incense smoke, the pagodas, the kimonos. Its all a bit Disney and historic at the same time. Gotta love Japan and its theatre.
