Try your hand at picking mikan at the Chikura Orange Orchard from October to April. But if you can't make it then, you can try the other fruit and vegetable picking experiences they offer year-round. Blueberries are in season from June to August. Other varieties of oranges, and citruses such as lemon, lime, and sudachi can all be found within the orchard at the right time of year. Load up on sweet potatoes plucked fresh from the ground in the fall.
