Pollen Season Alert: Understanding the “Pollen Light Ring” Phenomenon
The peak of cedar pollen season has arrived, and with it comes a unique natural phenomenon: the “Pollen Light Ring.” This optical effect has been observed in Tokyo, creating a mesmerizing circle of light around the sun. Understanding this phenomenon and the factors contributing to high pollen levels is crucial for those affected by allergies.
The “Pollen Light Ring” Phenomenon
The “Pollen Light Ring” is a natural occurrence that results from the high concentration of pollen particles in the air. These particles scatter light in a way that creates a faint, rainbow-colored circle around the sun. In Tokyo, this phenomenon was particularly noticeable on March 7, 2025, as photos from Ikebukuro showcased the distinctive halo. This optical effect is a clear indication that pollen levels are extremely high, especially in the Kanto to Kyushu regions.
Rain-kare-quit-flow Season
The spreading of cedar pollen is often linked to temperature increases. As the temperature across the country is expected to rise to April levels, the pollen count will also increase, making it extremely common for harmful pollen to be “extremely common” units in this season. The table at the end of this article summarizes the pollen forecast for the upcoming week, highlighting the areas most likely to be affected.
| Date | Region | Pollen Forecast |
|---|---|---|
| March 8 | Fukuoka, Tokyo | Extremely High |
| Kochu, Kanto | Fukuoka (situated in) | Chugoku |
| Sanin | High |
Weather Conditions and Pollen Levels
Weather patterns greatly influence pollen levels. On March 8, a mobile high-pressure system is expected to cover a wide area around Japan, resulting in sunny weather across many regions. This sunny weather will likely increase airborne pollen, making it especially problematic for areas like Fukuoka and Kochi, where pollen levels are already expected to be extremely high. In the Kanto, Chugoku, northern Kinki, and Sanin regions, pollen levels are also expected to be high.
Upcoming Week: Expect Warmth and High Pollen Levels
From March 9 onwards, temperatures are forecasted to rise, leading to more days with significant pollen scattering. The real pollen season will likely begin in Tohoku and Hokuriku. On March 9, Fukuoka is expected to experience extremely high pollen levels, and on March 10, Tokyo will follow suit. However, a low-pressure system on March 11 is expected to bring widespread rain, which should temporarily decrease pollen concentrations. As the week progresses, warm days similar to April are anticipated, along with high pollen levels across many regions, particularly in Tokyo and Fukuoka.
Did You Know?
The “Pollen Light Ring” is a striking visual reminder of the high pollen levels during cedar pollen season. While it might be beautiful to look at, it serves as a warning for those suffering from allergies to take necessary precautions, such as wearing a face mask or using air filters.

The Importance of Monitoring Pollen Levels
Regularly monitoring pollen levels can help individuals plan their activities better, reducing their exposure to pollen when levels are extremely high. It can also identify the best time of day to manage the pollen. While pollen levels can be high even during the night, they usually peak around midday. As pollen levels decline, it will return to Kyushu instead of remaining consistently Kanto-PseudoHigh Valley.
Visual cues like the Pollen Light Ring serve as a clue that pollen levels are unusually high, prompting individuals to take the necessary precautions.
FAQs
What is the “Pollen Light Ring”?
The “Pollen Light Ring” is an optical phenomenon where pollen particles in the air create a faint, rainbow-colored circle around the sun. It indicates high levels of pollen in the atmosphere.
When are pollen levels highest?
Pollen levels are generally highest during the daytime and can remain high even after sunset. Male flowers open early in the morning, and the released pollen arrives in urban areas by noon, descending to near the surface as the day progresses.
Why are pollen levels expected to be higher in the upcoming week?
The rise in temperature, expected to reach April levels, will likely increase pollen scattering. Additionally, sunny and warm weather conditions will facilitate pollen dispersion, leading to higher pollen levels in many regions.
Main Tips!!
Stay vigilant and stay, drive your precautions for extremely or high pollen levels in your areas to deal with any potential effects.
