As of February 16, the start of cedar pollen dispersal has been confirmed in parts of the region stretching from Kyushu to Tokai. By late February, dispersal is expected to begin across a wide area ranging from Kyushu to southern Tohoku. In Shizuoka Prefecture specifically, cedar pollen began dispersing in early February 2026; total volume is expected to reach 1.9 times the average of the past 10 years. Thick pollen is visible in the video, creating hazy conditions across the mountain range.
