Archaeologists have potentially discovered pottery from over 10,000 years ago at the bottom of Lake Biwa, Japan's largest freshwater lake located in Shiga Prefecture. The underwater exploration team found what appears to be ancient pottery fragments during a routine dive. Further analysis is currently being conducted to confirm the age and origins of the fragments, which, if estimates prove correct, could provide invaluable insight into the Jomon period, a pivotal era in prehistoric Japan.

Artifact discoveries such as this are of great importance in Japan, as they contribute to a better understanding of Japanese history, relate directly to the nation's cultural heritage, and often help to instill a general sense of national pride. The legal protections around archaeological sites and finds in Japan are robust, and such discoveries typically lead to further explorations and research, spurring scientific and cultural interest across the nation.

In the US or EU, similar discoveries would also be of significant interest. They are typically handled by archaeologists, universities, and other research institutions that work closely with government bodies committed to preserving cultural heritage. These discoveries not only add to the historical record, but also spur further education, research, and interest in local cultures and histories.
