Around the world, there are approximately 1 billion citrus trees thriving in countries ranging from Italy to Haiti, Vietnam to Senegal, and beyond. All of the world's commercial citrus fruits share three main ancestors: the Mandarin (Citrus Reticulata), the Pomelo (Citrus Grandis), and the Citron (Citrus Medica). The very first citrus ancestor evolved in northeastern India and the borderlands of southwestern China and Myanmar, as evidenced by the archaeological discovery of 8 million-year-old citrus leaves in Yunnan, China.
Today, citrus groves worldwide are dominated by Valencia, Navel oranges, Lisbon lemons, and Persian limes. However, indigenous groups still coexist with the wild ancient relatives of these fruits. In Meghalaya, the home of the Khasi tribe, you'll find villages scented with oranges and forests teeming with wild citrus. This region alone houses two-thirds of India's biodiversity. Citrus fruits here play various roles, including being placed on the dead during death ceremonies and serving as natural insecticides in the region's humid conditions.
The word "orange" originated from Hindi literature and, along the Silk Road, transformed into "neranji," eventually becoming "naranja" in Spain, "laranja" in Portugal, "arancia" in Italy, and "orange" in France. (Reference: Dan Saladino's 'Eating to Excitation')
While citrus fruits often evoke images of the Mediterranean in Europe, there's limited information about Japan's citrus production. Japan boasts over 80 types of citrus fruits, including the lesser-known Unshu mandarin orange, which thrives in regions like Wakayama, Ehime, and Shizuoka due to their similar Mediterranean-like weather.

One such citrus, "Yuzu," beloved by chefs worldwide, originally hails from the upper Yangtze River basin in China. It reached Japan via the Korean Peninsula, flourishing over 1300 years ago and finding use in medicine in western Japan. Japanese yuzu boasts an unmatched, rich aroma due to cultivation in inland mountain areas with significant day-to-night temperature fluctuations. Japan produces around 27,000 tons of yuzu annually, with Kochi Prefecture leading the way, contributing about 52% of the total. In Kochi, yuzu cultivation areas span 860 hectares, approximately 1200 times the size of a soccer field.

Ehime Prefecture, renowned for its delicious mandarin oranges, benefits from an ideal environment with abundant sunshine and nutrient-rich, well-drained soil. In the late 1900s, the number of farmers cultivating mandarin oranges surged, ultimately surpassing Shizuoka Prefecture's production levels by 1968. Ehime's sloping islands along the coastline, Chito Seto and Uchiuchi Islands, are particularly famous for producing these delectable mandarins.

Ehime mandarins thrive under the "three suns" of direct sunlight, sunlight reflected from the sea, and warmth radiated from the stone walls. While rice typically takes the spotlight as Japan's representative agricultural product, mandarin oranges reign supreme in Ehime, both in terms of production value and diversity. In 2011, Ehime produced approximately 260,000 tons of citrus varieties, making it Japan's top citrus producer.
Now, let's explore some of the key mandarin orange varieties:
