花火大会 (Hanabi Taikai) is a traditional Japanese fireworks festival held during the summer months. These events feature spectacular displays of colorful fireworks lighting up the night sky, often accompanied by music and food stalls. People gather in parks or along riversides to enjoy the show, wearing traditional clothing like 浴衣 (yukata). The origins of 花火大会 date back to the Edo period, when fireworks were used to ward off evil spirits and celebrate harvests. Today, these festivals attract large crowds, with some of the most famous events taking place in cities like 東京 (Tokyo) and 大阪 (Osaka).
