Asakusa Toro Nagashi

First held at the 1946 'Festival of Recovery' when much of Tokyo was still in ruins, the hauntingly beautiful Toro Nagashi lantern light-up was revived in 2005 after a 40-year break and now takes place in Sumida Park between Azumabashi and Kototoibashi. You can light your own lantern for ¥1,500, but enjoying the magnificent view of glittering fires on the Sumida River on a cool summer night is completely free.
