The 48th Adachi Fireworks Festival launched approximately 13,000 fireworks [1] over the Arakawa River in Tokyo on Saturday, May 30 [2].
The event marks a significant return for the community after the festival faced cancellations due to sudden thunderstorms in previous years. Organizers and residents sought to ensure the event's success this year after a three-year hiatus [3].
Hosted by the Adachi City Tourism and Exchange Association and Adachi City, the display lasted about one hour [3]. The scale of the event reflects a commitment to restoring local traditions despite the unpredictability of recent weather patterns.
While Tokyo celebrated, unstable atmospheric conditions affected northern Japan on the same day. A pressure valley carrying cold air passed through the region, leading to record-breaking rainfall in Aomori and Akita prefectures [4].
In northern Akita Prefecture, hailstorms were recorded [4]. Local residents described the intensity of the weather, noting that the sound of hail hitting roofs was overwhelming.
"There was a loud popping sound on the roof, and the sound was just incredible," a local resident said [4]. "Everything turned white, and it looked as if fertilizer had been spread across the flowerbeds."
The contrast between the celebratory atmosphere in the capital and the severe weather in the north highlighted the volatile spring climate across the archipelago [4].

The successful execution of the Adachi Fireworks Festival demonstrates the resilience of local cultural events against increasingly erratic weather patterns. However, the simultaneous occurrence of record-breaking May rainfall and hail in Akita underscores a growing trend of atmospheric instability in Japan, where extreme weather can coexist across different regions on the same day.
