As well as the usual varieties of vegetables sold in supermarkets everywhere, when venturing to areas outside of the major cities, there are an assortment of regionally native vegetables also available. Traditionally, varieties of regional vegetables varied greatly in each locality, such as the vegetables produced around Edo (now Tokyo), called Edo Yasai (or Edo Vegetables), differed greatly from Kyo Yasai (or Kyoto Vegetables), grown in Kyoto. Another example are the native vegetables called Kaga Vegetables and Kaga Kutani Vegetables, produced in Kanazawa City and Kaga City in Ishikawa Prefecture, each used to produce dishes unique to the area. Visitors to the region can enjoy quite unusual parfaits or Wagashi (Traditional Japanese Sweets) using locally grown native vegetables.
