Tōrō nagashi is a long-held Japanese tradition where candle-lit lanterns are released into rivers to guide the spirits of the departed back to the other world. I saw it for the first time at Shinobazu Pond in Ueno. It was a hauntingly beautiful sight, with a zen priest slowly releasing lanterns into the water from a rowing boat. In the darkness, the boat was barely visible, and so each lantern seemed to appear out of nowhere. Music in the video is by Zahn | Hatami | McClure. You can purchase the track here.
