Actual number of nagaimo depends on the weight/thickness of each item. Approximately 500g.
Whole nagaimo should be wrapped up in newspaper and stored in a dark, cool place in order to remain fresh longer.
Cut nagaimo should be tightly wrapped in plastic wrap, so that cut edges are covered. Once cut, store it in the vegetable drawer of the refrigerator.
For convenience, grated or shredded nagaimo can be kept in a freezer and broken off when needed. Just place it flat into a storage container first. Frozen nagaimo can last up to about four weeks.
