What region in Japan supplies over a third of the world's sake?

The correct response identifies Nada as the region in Japan that supplies over a third of the world’s sake. This area is located in the Hyogo Prefecture and is renowned for its sake production due to its unique combination of geographical and climatic factors that contribute to exceptional brewing conditions. The region benefits from pure water sources, especially from the famous Miyamizu water, and has a long-standing tradition of sake brewing that dates back centuries.

Nada is also home to many well-known sake breweries, making it a significant hub in sake production. The emphasis on using high-quality rice varieties and adhering to traditional brewing techniques further enhances the reputation of the sake produced in this region. This is why Nada stands out above other options, which may refer to specific brewing processes, rice types, or other regions, but do not encompass the same level of global sake production influence.
