Pollen Count & Forecast for Kobe

Kobe’s spring allergy season (February–May) is dominated by Cedar and Cypress pollen; Japanese Cedar (Cryptomeria japonica) is prolific across the Rokko Mountains; Japanese Cypress (Chamaecyparis obtusa) is widespread across urban districts through May. Mugwort (Artemisia) contributes to autumn counts from the Nunobiki hillsides. Summer (June–August) sees high Grass (Poaceae) pollen levels, originating from Suma Rikyu Park and along the Shin-Minato River.

The mountain-to-sea geography creates a trap for airborne particles; sea breezes push allergens against the steep slopes. High humidity during the summer rainy season increases Mould (Cladosporium, Alternaria) spore counts, from damp forests on Mt. Maya and leaf litter in Sorakuen Garden.
