While walking aimlessly in Tokyo, I came across what could be the smallest festival in the city. It just had one mini portable shrine and a crowd associated with the festival.
Still, even such a small festival has to be organised, especially because the shrine had to pass a four-lane street. The police just blocked enough of the street for the festival, while the other half remained unaffected. Of course, everything went smoothly.
For me, it was just another random find in the city of Tokyo. For the people who participated in this festival, it was likely the highlight of the year.
