Lake Kasumigaura
The water from Lake Kasumigaura has long been used for the irrigation of paddy fields in the surrounding alluvial plain and upland fields on diluvial terraces covered by thick deposits of volcanic ash. The primary crops are rice and lotus root (a local speciality). Other crops include tomato, cucumber, eggplant, watermelon, corn, edamame, sweet potato, kabocha, daikon and peanut.
