Origins and History of Lake Hamana Kanzanji Onsen Lantern Floating and Fireworks Festival
Lantern floating at Kanzanji Onsen has a history dating back to before the war.
It was suspended during wartime, but following the formation of the Enshu Tourism Association in 1948, a fireworks display became part of the Lake Hamana Summer Festival in 1949.
The event was canceled in 2020 and 2021 due to the COVID-19 pandemic.
