Tsushima and Tanegashima maintain pre-modern Japanese akamai cultivars; ceremonial-use lineage 1,500+ years.
Tannin / proanthocyanidin 0.5-2% in seed coat; protein 8-9%; brown-red colour distinct from anthocyanin black rice.
Akagohan (ceremonial red rice), niche-export functional rice, traditional-craft retail.
Ancient red-pigmented rice variety, historically the original Japanese rice before whitening cultivars dominated. Limited contemporary cultivation in Tsushima (Nagasaki), Tanegashima (Kagoshima), and pockets of Okayama. Often used in ceremonial rice-blends (akagohan), and increasingly as a niche functional-food and storytelling ingredient for export retail. Tannin and proanthocyanidin content distinguishes red rice from black rice (anthocyanin-driven) and white rice. Distinct from kuromai-black-rice and existing rice entries.
