Field notes
The growing section describes terraced gravel beds in Shizuoka and Nagano, supplied by spring water kept between 10 and 15 °C. For preparation, the page links the plant’s heat to broken cells and recommends gentle circular strokes with a fine sharkskin grater. Its recipe list ranges from sashimi to wasabi mashed potatoes; the homepage also says freshly grated flavor lasts about 15 minutes at its peak.
