Held in Koto-ku, this annual event sets off almost 4,000 colorful fireworks near the Arakawa River. That number might seem small compared to other hanabi events, but the festival draws huge crowds. This year, an estimated 300,000 will attend. The venue is just 15 minutes from the Minami Sunamachi Station, and the riverbank provides a friendly vantage point only 150 meters away from the launching site.
