Origin & Heritage
Where It Comes From
Shikuwasa grows wild and in cultivation across the Ryukyu Islands and is also found in Taiwan. In Okinawa it is most closely associated with the forested northern part of the main island, known as Yanbaru.
The fruit is used at two stages. Green fruit, picked from late summer, is squeezed for its tart juice. Fruit left to ripen into winter turns orange and is eaten fresh like a small mandarin.
In Okinawa, shikuwasa juice is a household staple — splashed over sashimi, stirred into water and tea, and mixed with awamori, the islands' traditional spirit.
Culinary Uses

Fresh juice

- 02
Coolers & tea
Shikuwasa juice diluted with chilled water or tea, lightly sweetened, is a classic Okinawan refresher.
- 03
With awamori
A squeeze of shikuwasa is the traditional partner for Okinawa's rice spirit, served on the rocks or with soda.
