A Japanese-style drain wet grater typically refers to a kitchen tool used primarily for grating vegetables like daikon radish or ginger. It usually consists of a wooden or plastic box with a removable grater inside and a drainage feature that allows excess liquid to be collected or drained away from the grated ingredients. The box packing likely refers to its packaging, which may include instructions in Japanese and English, and sometimes additional information about the product's usage and care. This type of grater is popular in Japanese cuisine for preparing ingredients finely grated or shredded, which is often used in dishes such as tempura, salads, and garnishes.
