Lake Suwa
In Japan, Lake Suwa froze up considerably earlier than normal in 1601, and flooding and continuous rains were accompanied by harvest failures. Korea in 1601 saw an unusually cold spring and summer, followed by a humid and hot mid-summer. Epidemics ensued, although the epidemics in East Asia erupted under different weather conditions and linking them to the Huaynaputina eruption may not be straightforward. On the other hand, temperatures were not unusually cold in Nepal.
