Earlier, the BBC News website reported that there was a fireworks explosion, injuring and seriously injuring about 50 people including children in Kyoto, and of which caused the cancellation of a fireworks display (BBC News). It was later revealed that it was a food stall or similar (like shown below) was using a generator and possibly was refilling the generator fuel tank when some fuel splashed onto the generator itself, causing a fire and explosion of the fuel tank. Then later a second fuel tank exploded, of which was recorded and released on the internet. Stalls like these below are typical scenes seen all over Japan for all festival and cultural events. See the Japan Today article for more information. These images, and others like them are available at my portfolio and my agent’s website.
Both images are typical stalls found at all Japanese festivals. The lights are typically powered by fuel generators.
