Wild Japanese grape (Vitis coignetiae) native to Tōhoku and Hokkaido. Dramatically smaller and more acidic than European wine grapes, but with anthocyanin and resveratrol concentrations 2–4× higher. Iwate Prefecture is the centre of commercial cultivation and processing — local cooperatives produce yamabudō juice, jelly, wine, and increasingly resveratrol-rich extract concentrates for the international supplement market. Iwate's Kuji and Kunohe districts have GI-protected branding for yamabudō wine.
