Tori no Ichi is said to have originated at Asakusa's Otori Shrine and the nearby Juzaisan Chokokuji temple, so you can expect a major spectacle here. This is the biggest Tori no Ichi festival in Tokyo with 800 to 900 booths selling kumade, souvenirs and plenty of food. The event attracts 700,000 visitors every year and gets very crowded in the evening, so go during daylight hours if you have the chance and snack on some old-school kiri-zansho candy.
The festival is held for 24 hours each day, starting with the first taiko drum sound at 12 midnight.
