As Japan shifts into spring, the weather is playing a dual role of providing unseasonably warm temperatures while also raising health concerns due to pollen and the impending arrival of yellow sand. Weather forecasts predict sunny skies over much of Japan on March 23, 2025, with temperatures soaring to levels typically expected in June. In particular, the Kanto region is expected to experience temperatures of 24 degrees Celsius in Tokyo, 23 degrees in Nagoya, 25 degrees in Fukuoka, and reaching 26 degrees in Miyazaki.
However, despite the pleasant weather, individuals suffering from allergies need to be vigilant. Along with cedar and cypress pollen expected to blow in the air, yellow sand is anticipated to make its presence felt, especially in areas like Sanin and Tokai later in the day. According to a weather expert, some people may experience adverse reactions if they go outside, especially those with pre-existing respiratory conditions. "People should consider wearing masks when stepping outdoors," the expert recommends.
The looming threat of yellow sand is not limited to March 23. From March 25 to March 26, a more significant influx is anticipated, with yellow sand set to sweep across the entire nation. Conditions are expected to worsen, leading to concentrations particularly high in western Japan. Historical comparisons show that similar events have previously caused visibility issues, including those observed in Fukuoka in April 2002, where visibility dropped to just 3 kilometers due to yellow sand, affecting air travel significantly.
Echoing these concerns, health authorities have warned citizens, particularly those with respiratory or circulatory disorders, to exercise caution. They advise reducing outdoor activities during higher concentration periods of yellow sand and wearing protective masks to help mitigate the breathing challenges posed by the weather. Keeping laundry indoors during yellow sand events is also strongly recommended to avoid contamination.
As we look into the week ahead, the onset of rain appears likely on March 24, mainly affecting the Sea of Japan side and parts of the East Sea. Furthermore, precipitation is predicted to linger in northern regions around March 26, extending to widespread rain from March 27 to March 29. Prohibition against laundry drying outside may also become a precaution, as residents will witness rain likely saturating the region.
Moreover, after the rains in late March, temperatures are expected to dip again, as a colder air mass will move in, bringing a return to chilly conditions. The forecast suggests a significant temperature drop after several days of warmth — a classic example of Japan's unpredictable spring climate.
The return of such cold air could lead to severe weather conditions in certain areas, reminding everyone of the continuous changes that Japan's weather can bring. As yellow sand and pollen fill the air, the advice remains clear: keep informed about weather forecasts, limit exposure, and take proactive steps to protect your health amid these fluctuating conditions.
In conclusion, while many may enjoy the warmth of spring weather, it is imperative to remain mindful of the potential health impacts of yellow sand and pollen. The interplay of high temperatures and airborne irritants paints a complex picture of Japan's meteorological landscape, requiring residents to navigate carefully in the coming days.
