Dekopon, also known as Shiranui, is a well-known Japanese citrus famous for its distinctive bump on the top and its excellent balance of sweetness and acidity.
After harvest, Dekopon are left to ripen for several weeks to nearly a month before being shipped.

Challenges of Growing Dekopon
Although Dekopon remains one of Japan’s most famous citrus varieties, production has gradually decreased in some citrus-growing regions of Ehime.
One reason is the aging population of growers, while another is the increasing shift toward newer premium varieties such as Kanpei and Setoka.
Dekopon also requires careful post-harvest storage. Large well-ventilated storage facilities are needed, and some fruit may spoil during storage before shipment.
Because the variety requires significant labor and time while market prices are not always especially high, some growers have gradually reduced production.
Even so, Dekopon continues to have strong popularity because of its balanced flavor, approachable sweetness, and refreshing acidity.
In many citrus-growing areas of Ehime, Dekopon is still considered one of the classic family-friendly Japanese citrus varieties.
