The water wasabi cultivation areas in the Izu region spread along the streams of the Amagi mountain range, with its highest peak at Mount Amagi standing at 1,406 meters. The water in this region is derived from rainwater that has percolated through layers of pumice and quartz andesite, volcanic deposits that provide an optimal balance of water volume, temperature, and nutrients for wasabi cultivation. The traditional farming method known as “tatami-ishi style wasabi fields,” which started in the Meiji era, has been recognized as a Globally Important Agricultural Heritage System. As the largest producer in Shizuoka Prefecture, the region consistently wins awards such as the Minister of Agriculture, Forestry and Fisheries Prize and the Director-General of the Forestry Agency Prize, ensuring its status as one of the top-quality producers in Japan. The wasabi from this region is distributed almost nationwide, including the Kanto, Chubu, and Kansai regions, and is renowned for its high profile and esteemed by chefs for its exceptional quality.
