Kito yuzu

Naka Town in Naka District, Tokushima Prefecture, forms the production area for Kitou yuzu. The terrain is enclosed by mountains over 1,000 meters and more than ninety percent forest, with a cool climate, heavy summer rain, and large differences between day and night temperatures. Those conditions are linked with vivid color, strong aroma, and fruit that resists disease. The landscape matters at the level of the peel: the place connection is visible not as scenery alone, but in a citrus fruit sorted for appearance, squeezed for juice, and used for acidity.

Long before recent product development, yuzu trees in this area grew near house fronts and along field ridges. When people spoke of “vinegar,” they often meant yuzu-su: squeezed, unfermented yuzu juice, seasoned with salt and kept for cooking. It went into dressed dishes, fish, and hot-pot meals. In the former Kito area, hand squeezing and wooden presses also belong to the juice-making work, so the sharpness of Kitou yuzu starts in kitchens before it appears in processed juice or peel.

Modern production activity took shape in 1960, when six volunteers from former Kito Village sent trial fruit to Osaka Central Market and the effort became a trigger for full-scale production. In 1961, local seedling work began for strain selection. Production later expanded through the Naka River basin to five towns and villages that are now within Naka Town. The timeline is concrete: six people, one market trial, seedling work the following year, and a river basin that carried the fruit beyond the old village boundary.

Kitou yuzu is described through thick peel, few peel blemishes, clean appearance, vivid color, high aroma, and strong acidity. Its geographical indication gives context to a practical boundary: varieties selected from native Naka Town strains, cultivation standards set by the producer group, and sorting rules for fresh and processing fruit. Fresh fruit for shipping must be at least 4 centimeters in diameter and free from loose wounds or puncture wounds. Fruit outside that fresh standard can still move to processing when it is not badly damaged, harmed by pests, or rotten.

After sorting, Kitou yuzu can travel through juice, peel, and seasoning rather than only through fresh fruit. Regional processing examples include squeezed juice, ponzu, tea, jam, marmalade, powder, frozen juice, frozen peel, cider, and yuzu kosho. Each form holds a different part of the citrus: acidity in juice, fragrance in peel, and a sharp edge in condiments and drinks. The range also keeps the fruit useful when appearance or size sends sound fruit away from the fresh-fruit line.

Recent regional work has joined agricultural cooperatives, local companies, and public bodies around processing, local cooking, food fairs, and chef outreach. Product-development examples include ponzu, canned chuhai, and jelly; export examples include fresh yuzu for French food service and processed forms such as frozen juice and frozen peel reaching Thailand, France, the United States, and other markets through a Naka Town processor. Alongside fruit and juice, the same processor handles items such as cider, yuzu kosho, and fragrance products, showing how aroma, acidity, and peel can move through separate food and craft pathways.
