Kabosu is Oita’s signature citrus fruit, and the prefecture grows the overwhelming majority of Japan’s entire crop. A round, green citrus resembling a large lime, kabosu is prized not for eating whole but for its fragrant, tangy juice, which is squeezed over food much like a lemon or lime but with its own distinctive, refreshing aroma and a milder, more rounded acidity. In Oita it’s a beloved everyday condiment: a squeeze of kabosu brightens grilled fish and sashimi, the region’s famous Seki-saba and Seki-aji, Bungo beef, toriten, hotpots, noodles and even miso soup, and it’s used in ponzu, dressings, drinks, sweets and more. Green kabosu is harvested from late summer into autumn, and the citrus gardens of Oita are laden with the fruit in season. Trying kabosu squeezed over local dishes is to taste the flavour of Oita itself.

Tips
Squeeze fresh kabosu over grilled fish, sashimi, toriten or Bungo beef to taste why locals love it, and look for kabosu-flavoured drinks, sweets, ponzu and dressings as souvenirs. It’s harvested from late summer into autumn when it’s freshest, buy some to take home, and use it anywhere you’d use a lemon or lime.
