Asakusa Toro Nagashi (2014)

First held at the 1946 'Festival of Recovery', 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.
