The Adachi Fireworks Display returned to the Arakawa Riverbed in Tokyo on Sunday, marking the first time the event has been held in three years [1, 2].

The revival of the festival represents a significant cultural milestone for the local community after years of disappointment. The event is considered a staple of the region's summer traditions, and its return follows a period of instability caused by weather-related cancellations.

Approximately 680,000 people attended the event [1]. The crowd included many residents who had waited since the festival was canceled in 2024 and 2025 due to poor weather [2]. The organizers shifted the event to an earlier date this year to avoid the conditions that led to previous cancellations [3].

Despite the celebration, the high temperatures took a toll on some attendees. Several people were transported by emergency services to hospitals after suffering from heatstroke [1, 2].

Attendees expressed relief that the event finally proceeded. "I was devastated when it was canceled at the last minute the year before last and last year," said a man in his 30s. "I really thought this year would be the one, and I am truly looking forward to it," he said [1].

Other visitors noted the timing of the event in relation to traditional clothing. "It is always hot in the summer, isn't it? That is why, if you are going to wear a yukata," said a university student [1].

While most reports confirm the event's success, some conflicting information emerged regarding the Sunday schedule. A representative for the Adachi City Tourism and Exchange Association said that a decision to cancel would be made if strong winds threatened to scatter firework debris [3]. However, the primary reporting indicates the display was successfully completed with a massive turnout [1, 2].

“Approximately 680,000 people attended the event”

The return of the Adachi Fireworks Display underscores the tension between maintaining traditional cultural festivals and the increasing unpredictability of weather patterns. By shifting the event date to avoid the cancellations seen in 2024 and 2025, organizers demonstrated a strategic adaptation to climate risks, though the resulting heatstroke cases suggest that moving the date creates new public health challenges.
