Sudachi is believed to have originated in Japan, specifically in the Tokushima Prefecture on Shikoku Island. The fruit has been grown in Japan for centuries, with references to sudachi appearing in historical texts dating back to the Edo period (1603–1868). It has its name from the way it is consumed, as the name “sudachi” is a combination of “su” (vinegar) and “tachibana” (a traditional name for another citrus fruit). It is often compared to yuzu and kabosu but is prized for its unique tartness and aroma. Sudachi is a key ingredient in regional cuisines, particularly in Tokushima, where it is celebrated in local dishes. The juice is squeezed and used in place of vinegar. The cultivation and sale of sudachi have contributed significantly to the local economy in Tokushima Prefecture. It is often featured in local festivals and is an important agricultural product for the region. In recent years, sudachi has gained popularity beyond Japan, recognized by chefs and food enthusiasts for its versatile flavor and is being increasingly used in gourmet dishes, cocktails, and international cuisine.
