Japanese Rice Varieties Koshihikari Akitakomachi and Selection

Japan — Niigata Prefecture, developed 1956; Koshihikari now the most widely planted variety in Japan accounting for approximately 35% of total rice acreage

Japan's rice culture is built on Japonica short-grain varieties bred specifically for the characteristics valued in Japanese cooking: high stickiness (amylopectin-to-amylose ratio), translucent appearance when cooked, slightly sweet flavour, and the capacity to hold shape in onigiri and sushi while remaining tender. The dominant varieties: Koshihikari (developed 1956, grown in Niigata, Fukui, and across Japan) is the gold standard — prized for its balance of stickiness, sweetness, and glutinous texture; Akitakomachi (developed 1984, grown in Akita Prefecture) is considered slightly firmer and less sweet, preferred in some northern regions; Hitomebore (Miyagi Prefecture) and Haenuki (Yamagata) are regional prestige varieties. Uonuma Koshihikari from the mountain regions of Niigata's Uonuma district commands the highest prices in Japan.

Clean, milky-sweet, slightly glutinous; the baseline flavour of Japan — against which everything else is measured
