Answer: Japan
Notes: Researchers found a nearly intact ancient pottery vessel near Lake Biwa in Shiga Prefecture, dating back over 10,000 years. It is Japan’s largest freshwater lake on Honshu, about 64 kilometres long and 672 square kilometres in area. The lake looks like a biwa musical instrument and is over four million years old. It is fed by mountain rivers and drains into Osaka Bay through the Yodo River. It supports fish, pearl culture, water supply, textile industries, and was listed under the Ramsar Convention in 1993.
