Kabosu香母酢 (kabosu)
Mellow. Juicy. Balanced.
Kabosu is the generous one: larger than sudachi, softer in its acidity and full of juice. In Ōita it is squeezed over everything from sashimi to hot pot.

Origin & Heritage
Where It Comes From
Kabosu is the signature citrus of Ōita Prefecture in northeastern Kyushu, which produces most of Japan's kabosu. Old trees can still be found around the region, and the fruit is closely tied to local food culture.
Like sudachi, it is usually harvested while green, when its acidity is most refreshing. Left to ripen, the skin turns yellow and the flavor becomes softer.
Because the fruit is larger and juicier than sudachi, kabosu is often used in more generous quantities — in dressings, drinks and as a seasoning for whole dishes.
Culinary Uses
In the Kitchen

Over fish & hot pot
Squeeze over sashimi, grilled fish or a steaming nabe hot pot. The mild acidity brightens without overwhelming.

Juice for dressings
Its gentle acidity makes kabosu juice an easy substitute for lemon in vinaigrettes and marinades.
- 03
Soda & highballs
Kabosu with honey and soda water, or in a shochu highball, is a refreshing late-summer drink.
