关于本原料
Native Japanese yam (Dioscorea japonica) and the related cultivated nagaimo (D. opposita), distinguished by the viscous mucin-rich tuber flesh that drives both culinary and functional positioning. Aomori produces over 50% of Japan's nagaimo for export and domestic processing; jinenjo (wild yamaimo) commands premium pricing in retail and restaurants. Used in tororo, okonomiyaki batter, soba-noodle binder, and increasingly as a freeze-dried functional ingredient for digestive-support supplements.
