Since my inn was just a 10 minute walk from the Sensoji Temple, it was my favorite place to start the day, or rest after a day of sight seeing. If possible, see the temple in the early morning. An amazingly peaceful place in the morning mist as the sun rises. No stalls full of venders, no loud crowds. Just the statues, the running water, the clink of coins as the occasional dark-suited businessman on a bicycle stops by to pray on his way to work. After an hour or so about 50 or 60 school children will come though on a field trip, all in their matching uniforms. Since there are so many schools in Tokyo, apparently you can expect a group about every day. Not that it is a bad thing. Personally I prefer their cuteness and excitement over the packed crowds during the afternoons and evenings. Oh ok, indulge the tourist in you and see all the stalls full of T-shirts, key chains, and folding fans. One midday walkthrough was enough for me. Night is another great time to visit, after the venders have closed shop. You will have it almost all to yourself again. Except if you happen across a model photo shoot like I did. The only time the crowds are enjoyable is during the huge Sanja Matsuri; a festival held every May. It is a must see if you are in Tokyo at that time. All of Asakusa is alive with chanting and drums as golden shrines are marched though the streets.
