Today, the 27th, was sunny and windy, and a “pollen halo” that can be seen when a large amount of pollen is scattered could be seen in Tokyo. Tomorrow, the 28th, it will be sunny and there will be a lot of pollen in many places. Take all possible precautions.
Pollen halo appears in Tokyo
Pollen dispersal is increasing even in Tokyo. Yesterday, the 26th, was sunny and windy, and a large amount of pollen was scattered: 2844.8 pollen/cm2 in Ome, 936.1 pollen/cm2 in Hachioji City, and 759.0 pollen/cm2 in Tachikawa.

Today, the 27th, the Kanto region is still sunny and strong winds are blowing. In Tokyo, a “pollen halo”, which can be seen when a large amount of pollen is scattered, was observed.
Pollen haloes look beautiful in photos, but they are evidence of large amounts of pollen being scattered. If a pollen halo appears, those with hay fever need to take thorough measures.
When photographing the pollen halo, it is easier to photograph the pollen halo by hiding the sun behind buildings, street lamps, leaves, etc. However, when taking pictures, please be careful not to look directly at the sun with your naked eyes.
Be careful after the rain for “massive scattering”
Tomorrow, the 28th, it will be sunny and there will be a lot of pollen in many places. It is predicted that there will be a “high” number of cases in Tokyo, Nagoya, and Hiroshima, and a “very high number” of cases will occur in Osaka, Kochi, and Fukuoka. People with hay fever need to take thorough measures.
On the 29th (Thursday), the rain will spread from the west, and the scattering of pollen will be suppressed in many places. The rain will gradually stop from the west on Friday, March 1st, and the weather is expected to improve during the day. Pollen dispersal will increase again. From March 3rd (Sunday) to March 4th (Monday), it is likely that there will be “very heavy” dispersal widely from Kanto to Kyushu.
What is the peak of pollen scattering?
Already in some parts of Kyushu, Tokai, and Kanto, extremely high amounts of cedar pollen have been observed. The peak season is expected to continue in Fukuoka until early March and in Takamatsu until mid-March. Hiroshima, Osaka, Nagoya, Kanazawa, Tokyo, and Sendai will reach their peak in early March. The peak period is expected to last from about 10 days to nearly a month. Particularly on sunny, warm days or windy days, the amount of pollen scattered increases, so please take thorough measures to prevent pollen.
Additionally, cypress pollen peaks in many places from late March to early April. In Sendai, the amount of cypress pollen scattered is small, and no clear peak is expected to appear.
