Yamada Nishiki rice is still very much a part of the modern Aiyama rice strain, as it is one of its ancestors. It is renowned for its ability to produce fragrant and fruity sake, while it is also one of the most challenging rice types to cultivate. This is because it needs to be grown in regions that have an uneven terrain and that can protect the rice from being flattened by the wind. As a result, Yamada Nishiki rice is more expensive, yet widely accepted as a king of sake rice varieties in several locations like Shiga, Kanagawa, Tokushima, Fukuoka, and Okayama. Therefore, if you are looking for high-quality sake, it could be a great option to bear in mind.
