The Dogtooth Violet Festival is held in the middle of April at Kami-Gaito in the west of Hata. Dogtooth violets are wild flowers which grow in the northern Japanese mountains. They bloom early in April. The flower has six beautiful violet petals. On the leaves, there are unique purple spots. From the roots, people used to make a kind of white starch called "Katakuriko." But nowadays, the starch is made from potatoes instead. Years before the dogtooth violet garden was a mulberry field. The landowners have since protected the wild flowers in the field. Since 1997, the neighborhood has made a sidewalk and taken care of the area. Now, the garden has about 20 kinds of wild flowers and about 30,000 flowers in total. During the festival, which lasts for two weeks, there is a 200 yen entrance fee to the garden.
