Sensoji Temple is one of the biggest, must-see sites in all of Tokyo and Japan itself. It is worth the visit despite the crowds that flood its grounds every day (during normal times).
Sensoji Temple, also known as Asakusa Kannon Temple, is a Buddhist Temple set in the middle of Asakusa and is Tokyo’s oldest temple.
Originally built in 645, the temple is a major attraction for tourists that draws people in with its history, features, and brightly colored grounds that are a photographer’s dream when they think about filming Tokyo.
The main entrance to the temple grounds will take you through the Kaminarimon, also known as the Thunder Gate which leads directly into the 200 meter long Nakamise Street. Nakamise Street is known for its stores that sell all sorts of souvenirs and foods as you make your way to the main temple itself. You will know you are on Nakamise Street by just the volume of people that are usually shopping the area (during normal times).
The temple is open from 6:00 AM to 17:00 PM and there is no admission fee to enter the temple (do not take photos of the inner part of the temple though). The temple grounds themselves are never closed, so you can explore the grounds after dark to get some incredible pictures and video of it (many do this) so take advantage of that if you want to really want some great pictures without the large crowds.
Overall, Sensoji is a wonderful site to visit while exploring Tokyo, one that I have visited multiple times now and highly recommend to anyone wanting to see Tokyo.
