Sudachi vs. Kabosu: Two Japanese Citrus Fruits Worth Discovering
Both are green, both are squeezed over food, and both are often mistaken for limes. A guide to telling these two seasonal citrus apart — and using each well.

Sharp. Fresh. Vibrant.

Origin & Heritage
Where It Comes From
Sudachi is closely associated with Tokushima Prefecture on Shikoku, which grows the great majority of Japan's crop. The fruit's white blossom is the prefecture's official flower.
It is a close relative of yuzu, but it is harvested young, while the skin is still green, when acidity and fragrance are at their sharpest. Left on the tree it will slowly turn yellow and mellow.
In Tokushima, sudachi is less an ingredient than a habit: halved and set beside almost anything — grilled fish, soba, miso soup — so each person can season to taste.
Culinary Uses
In the Kitchen

The last squeeze
Halve across the middle and squeeze over food just before eating. Classic partners are salt-grilled Pacific saury, matsutake mushrooms and tempura.
- 02
Thin slices
Paper-thin rounds float on chilled soba or udon, and add a bright green note to sashimi platters.
- 03
In the glass
A wedge of sudachi in a highball, beer or sparkling water gives a crisp, lime-like edge with a more delicate perfume.
