Fatal tick-borne disease cases in Japan surge faster than in 2025

Japan is witnessing an alarming rise in cases of a potentially fatal tick-borne infectious disease. Preliminary data from a national medical research agency shows that infections this year have already outpaced the record rate recorded in 2025.

Scientists warn that the disease, which typically causes high fever, rash, and multi-organ failure, is spreading faster than anticipated. The reason is believed to be climate change, which has extended the tick season and widened their habitat range.

Japanese health authorities are urging people to take precautions during outdoor activities, especially in wooded areas and tall grass, while stepping up surveillance to prevent a large-scale outbreak.
