Wasabi is a specialty of Okutama, the Okuzashiki (living room) of Tokyo. Yamashiroya sells Wasabi-zuke (Wasabi pickles) that use plenty of fresh Wasabi from Okutama. Wasabi-zuke, which has been made here for 75 years is created by a carefully cultivated traditional method and is very popular with side dishes and sake. It has a rich repertoire as a flavoring on such items as cheese Wasabi pickles and kazunoko Wasabi.  This makes it a perfect souvenir to bring from Okutama.
