100,000 LED Lights Float Down The Sumida River

The inaugural Tokyo Hotaru festival was held last weekend. And kicking off the festivities were an impressive display of 100,000 LED lights – made to resemble hotaru (fireflies) – that floated down the Sumida River through central Tokyo. Dubbed “prayer stars,” the LEDs were provided by Panasonic, who claims that the balls, which were designed to light up upon contact with water, were 100% powered by solar energy. After illuminating a large stretch of the river, which also hosts a popular fireworks festival in the summer, the LEDs were all caught in a large net. There are plenty of literary references indicating that the Sumida River was once home to real fireflies, which were said to gather around clean, running water.

Most Colorful River In The World

During Colombia’s wet season, the water flows fast and deep, obscuring the bottom of the river and denying the mosses and algae that call the river home the sun that they need. And during the dry season there is not enough water to support the dazzling array of life in the river. But during a brief span between the wet and dry seasons, when the water level is just right, the many varieties of algae and moss bloom in a dazzling display of colors. Blotches of amarillo, blue, green, black, and red – and a thousand shades in between – coat the river.
