Tsuyahime
Yamagata's glossy, restrained-sweetness flagship
Named for its glossy sheen, said to have firm grains and measured sweetness; Yamagata gave it a prefecture-wide full debut as a brand rice in 2010. Said to have repeatedly earned 'special A' ratings, with yields deliberately capped to protect quality.
Lineage
What it's made of
Said to turn glossy on cooking, with a whiteness and shapeliness to the grain that catches the eye. Its sweetness is said to be gentle, balanced against its stickiness, bred for a top-tier taste said to rival or exceed Koshihikari, reportedly carrying more of the umami compounds glutamic and aspartic acid as well. Its aroma on cooking is said to be gentle and refined, with notably large grains, prized for both appearance and taste.
How it's made
Said to have been crossed in 1998 at a Yamagata experiment station's Shonai branch, with 'Tohoku 164' as father and 'Yamagata 70' as mother, given the local line name 'Yamagata 97' in 2005 and named Tsuyahime in 2009. Shipping standards said to cap crude protein content at 6.4%, prioritizing quality over yield.
Why it took this shape
Yamagata is said to have thrown its weight behind branding the variety, giving it a full debut in 2010. That debut year brought record heat, yet the rice is said to have hit the nation's highest grade-one ratio, proving its quality under pressure. The Shonai region's inland climate and wide day-night temperature swing are said to underpin its sheen and flavor. The Shonai region is also said to be blessed with abundant water from the Mogami River and the sharp temperature swings of its basin terrain, a climate said to bring out the rice's sheen and sweetness.

Dishes in the same style
- AkamaiAn ancient category of rice said to carry a reddish bran layer; low-yielding but tied, it's said, to Shinto harvest rituals still kept at shrines like those on Tsushima. Traces of red rice are said to have been found at Jomon- and Yayoi-era sites, making it among Japan's oldest rice lineages.
- AkitakomachiA Koshihikari cross bred for Akita's cool climate, said to carry a lighter sweetness and moderate stickiness, long favored as an everyday table rice. Named, it's said, after the legendary beauty Ono no Komachi, it ranks among Japan's most widely planted varieties.
