Wikipedia definition
2. Dioscorea oppositaDioscorea opposita (nagaimo, Chinese yam, Korean yam) is a type of yam that may be eaten raw. Dioscorea opposita is an exception to the rule that yams must be cooked before consumption (due to harmful substances in the raw state). In Japanese cuisine, it is eaten raw and grated, after only a relatively minimal preparation: the whole tubers are briefly soaked in a vinegar-water solution, to neutralize irritant oxalate crystals found in their skin.
