Shirataki (Japanese: 白滝, often written with the hiragana しらたき) or ito-konnyaku (Japanese: 糸こんにゃく) are translucent, gelatinous traditional Japanese noodles made from the konjac yam (devil's tongue yam or elephant yam).The word shirataki means 'white waterfall', referring to the appearance of these noodles. Largely composed of water and glucomannan, a water-soluble dietary fiber, they are very low in digestible carbohydrates and food energy, and have little flavor of their own.

Shirataki noodles come in dry and soft "wet" forms in Asian markets and some supermarkets. When purchased wet, they are packaged in liquid. They normally have a shelf life of up to one year. Some brands require rinsing or parboiling, as the water in the packaging has an odor some find unpleasant

The noodles can also be drained and dry-roasted, which diminishes bitterness and gives the noodles a more pasta-like consistency. Dry-roasted noodles can be served in soup stock or a sauce.
