- The Rainy Season in Japan has officially ended for central, eastern, and northeastern regions.
- The season concluded earlier than average in Kanto-Koshin, Hokuriku, and southern Tohoku.
- A high-pressure system now dominates, promising sunny weather in eastern Japan for the coming week.

Rainy Season Comes to an Early End in Japan
The Japan Meteorological Agency has announced that the rainy season, or ‘tsuyu,’ has officially ended for large parts of Japan’s central, eastern, and northeastern regions. According to the announcement on Friday, the rainy season is over in areas such as the Kanto-Koshin region (which includes Tokyo), along with Hokuriku and the southern part of the Tohoku region. This marks an unusually early conclusion to the season. In some regions, this milestone occurred nearly two weeks earlier than average.
Statistical Insights into an Earlier End
Significantly, the rainy season’s end in the Kanto-Koshin region is just one day earlier than the historical average. Hokuriku, however, sees a more substantial difference, with the mild-weather season ending five days earlier than usual average and an astounding 13 days earlier than the same event last year. In southern Tohoku, locals are witnessing a conclusion that is six days earlier than average and a striking 14 days earlier than in 2022.
Weather Conditions Post-Rainy Season
The early end of the wet season is attributed to the dominance of a high-pressure system across Japan. This weather pattern has brought clear skies to eastern parts of the country, an occurrence that is expected to prevail in the coming days. With more sunny days on the horizon, residents and tourists alike can anticipate a stretch of pleasant weather.
The Impacts on Agriculture and Lifestyle
The early cessation of the rainy season can have mixed consequences. For farmers, the shortened wet period may impact crop yields, particularly for crops that rely on abundant water during the rainy season. Conversely, urban dwellers and tourists may welcome the sunny skies, especially with summer events and outdoor activities now more accessible and enjoyable. However, authorities and citizens alike are encouraged to remain vigilant about potential heatwaves, a common occurrence in Japan as summer progresses.
Looking Towards Summer
With the rainy season over, much of Japan will transition fully into summer mode. Beaches, parks, and outdoor recreational areas will likely see increased activity as people celebrate the sunny conditions. Festivals and cultural events that rely on good weather are expected to draw large crowds, contributing positively to local economies.
Commentary
The Early End of the Rainy Season: A Positive for Most?
The early cessation of the rainy season in Japan’s central, eastern, and northeastern regions has sparked interesting conversations about its implications. While the end of ‘tsuyu’ is often greeted with relief by people eager to escape the humid, damp conditions, this year’s earlier-than-usual conclusion raises questions about Japan’s changing climate and its broader impact on daily life.
Will Sunny Days Herald Optimism?
The promise of more sunny days brings an undeniable sense of optimism to many. From locals planning summer outings to businesses preparing for an influx of tourists, clear skies undoubtedly have a positive economic and cultural impact. Events hosted in cities like Tokyo, which were often marred by unpredictable weather, can now proceed confidently. Additionally, fewer rainy days might mean safer travel conditions, reducing risks like landslides or train disruptions common during tsuyu.
A Reminder of Climate Dynamics
However, the abrupt end of the rainy season warrants attention to climate-related issues. Meteorological changes that cause significant deviations from seasonal norms often serve as a reminder of the ongoing effects of global climate change. For farmers, this could mean adjusting plantation and irrigation strategies to adapt to shorter wet periods. Failure to adapt could result in reduced yields or quality for crops like rice that rely on consistent rainfall during early growth stages.
The Balance Between Benefit and Concern
As Japan embraces the sunny aftermath of this year’s shortened rainy season, it becomes evident that while clear skies bring numerous upsides, they also come with responsibilities. These include preparing for potential heatwaves and considering the long-term impacts of shifting weather patterns. Ultimately, a balanced approach is crucial to mitigating risks while enjoying the benefits of a brighter, sunnier start to summer.
