Okitsu mandarines mature early —between September and October — and can be eaten even when their peel is still green.

They have a pleasant aroma and great taste. They are of medium size, slightly flattened in shape, with greenish-yellow peel turning to orange-salmon, with rough skin, making them easy to peel. They provide lots of vitamins and minerals; they have bronchodilator and anti-inflammatory properties; and help digestion in the intestine.
