At the market, there are over 200 stalls you can check out. Mostly selling this plants ,but there are other shops such as souvenir shops, wind bell shops etc. It is said if you visit Sensoji Temple on these festival days ( July 9 and 10 ), it is worth that you visit 46000 days = 127 years !!!
If you are in Tokyo and wonder where to go, this could be a choice.
