Japan is experiencing significant temperature fluctuations as March progresses, with weather changes expected across various regions. According to forecasts, the northern region of Tohoku is anticipating increased snowfall, particularly on March 6, 2025, as weather conditions continue to evolve.
On March 8, the Kanto region will see cold rain or possibly snow at night, bringing mid-winter conditions to many areas. Weather experts warn of temporary weather changes, including snow turning to rain on March 5, which will occur just before this expected dip.
Reports suggest the northeastern areas will maintain snowy conditions, mainly along the Sea of Japan side by March 7, and the rest of Kanto down to Kyushu is expected to be clear. This clear weather is not set to last, as changing fronts will bring rain to eastern and western Japan after March 9. Forecasts show temperatures will fluctuate greatly during this period, leading to colder weather with the potential for significant temperature drops in specific regions.
Notably, temperatures on March 8 are expected to feel particularly grim as wind chill could amplify the cold sensations felt across Kanto and Tokai regions. Meteorologists predict around March 12, the weather could drastically shift to above-average temperatures, allowing for more comfort without coats.
From March 14 to 18, the report states, rain will gradually encroach from western to eastern and northern Japan, with heavy snow also expected for Hokkaido. The variability of the weather signifies the need for residents to remain prepared for unexpected switches, particularly with increasing reports of pollen dispersal expected as warmer air moves from the south.
By the weekend of March 8-9, Japan's winter pressure pattern will ease, pivoting the country under high-pressure systems. Although this high-pressure system might not be strong, forecasters warn cloudiness is likely, especially around the Pacific sides of western and eastern Japan.
Importantly, strength and behavior of low-pressure movements off the Kanto coast could lead to local rain showers during the weekend. Experts strongly recommend updating plans based on the latest weather forecasts, as conditions can change swiftly.
While temperatures around March 9 will trend toward being colder than average, predictions for the following week indicate significant warming. Starting March 10, 2025, temperatures will rise nearer to the average or even slightly above, heralding the return of spring like weather, which could significantly benefit the cherry blossom season due at the end of March.
Nevertheless, the arrival of warmer weather does correlate with the increase of pollen dispersal, which may exacerbate allergy symptoms for many. Consequently, residents are encouraged to take precautions such as wearing masks or glasses and implementing proper ventilation techniques inside their homes to manage discomfort.
With frequent changes and transitions expected throughout the month, residents and visitors alike should remain attentive to the daily forecasts as the next moments of weather phenomena evolve.
