Tokyo’s sentinel surveillance weekly reporting highest record of Kawasaki disease cases in spring 2025 should be regarded as the key predictive indicator of a 2018-like situation, given Japan’s lack of rapid reporting of cancer incidence and the 2018 coincidence of extreme pollen levels with peak Kawasaki disease, cancer, and designated intractable disease incidence
