The Lake Suwa Fireworks Festival, held each August, is one of Japan’s largest and most spectacular fireworks displays, launching tens of thousands of shells over the lake in a show that lasts around two hours. The surrounding mountains form a natural amphitheatre that amplifies and echoes the booms, while the lake reflects the bursts across the water, creating an overwhelming sensory experience; a separate autumn ‘new fireworks championship’ also showcases innovative competitive pyrotechnics, making Suwa one of Japan’s premier fireworks destinations.
