Which prefecture would you associate with significant sake production, along with a rich history, especially noted for its rice?

Hiroshima Prefecture is well-known for its long-standing tradition of sake production, which is closely tied to its agricultural practices, particularly the cultivation of high-quality sake rice such as "Hattan Nishiki" and "Ginjo," which contribute significantly to the brewing of premium sake. The geographical features of Hiroshima, including its climate and water quality, are conducive to sake brewing, making it one of the leading sake-producing regions in Japan. The rich history of sake production in this area, along with the emphasis on local rice varieties, further establishes Hiroshima as a key player in the sake industry, renowned for crafting refined and flavorful brews.

While the other prefectures mentioned may have some level of sake production, they do not match the historical significance or the specialized rice growing practices associated with Hiroshima, which plays a pivotal role in its sake brewing identity.
