Tokyo Tower has been celebrating the coming of spring with a special Setsubun ceremony every year since the tower's opening in 1958. This year’s edition, the 64th, will be held on the second floor of the Main Deck from 10:45am to 11am, when monks from nearby Zojoji Temple will perform their rites. After that you can join the tower's official mascot, Noppon, as well as the mascot for Ishikawa prefecture’s Komatsu city, Kabukki, in the ritual throwing of beans and candies.
The event is free, but you’ll need to purchase a ticket to enter Tokyo Tower.
