Omachi
the century-old ancestor of many sake rice lines
Said to have been found in Okayama in the closing years of the Edo period, an ancestor of many modern sake rice lines, said to give sake a rich, distinct body. Said to be labor-intensive to grow as a sake rice, with its rarity rising as fewer farmers keep growing it.
Lineage
What it's made of
Said to have large, soft grains with a big starchy core, yielding a sake with a distinct aroma and flavor unlike Yamada Nishiki's. Said to lend itself to a rich, full-bodied sake, and said to have been judged top-grade at competitions in the early Showa era. Said to be labor-intensive to polish, and its tendency to break is said to make it less suited to very heavy polishing. Its aroma is also said to give a more grounded, earthy impression than Yamada Nishiki's.
How it's made
Said to trace back to 1859, when Kishimoto Jinzō is said to have found an unusual rice plant on his way home from a pilgrimage to Mount Daisen and raised it near what is now Okayama's Ward of Omachi. Standing about 1.8 meters tall, it's said to be prone to lodging and vulnerable to pests and disease, making it labor-intensive to grow. Its cultivation is said to have spread across Okayama afterward, with seed shared with breweries across western Japan from the Meiji through early Showa eras.
Why it took this shape
Said to run through the lineage of roughly two-thirds of existing sake rice varieties, an ancestor of many prized varieties including Yamada Nishiki and Gohyakumangoku. Its difficulty in cultivation is said to have let Yamada Nishiki eclipse it for a time, but its distinct character is said to be drawing renewed interest, with fewer farmers still growing it adding to its rarity. In recent years Okayama is said to have pushed to promote its cultivation, with events showcasing sake brewed from Omachi held around the country. Tasting events gathering only sake brewed from Omachi are also said to be popular.

- 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.
