Satsumaimo Japanese Yam + Recipes

Yams or “Satsuma Imo” were first introduced to Japan in the Ryukyu Islands (Okinawa) in 1604 by the Chinese. They were then introduced in Kyushu in 1609, an area that grows 80% of the total Japanese production.


Sweet potatoes should not be confused with yams or yama imo/山芋 in Japanese.


They have been recognized in this country for a long time for both their nutritional and pharmaceutical values.

Description/Taste Satsumaimo sweet potatoes have garnet colored skin and a pale cream colored flesh when raw. Once cooked the flesh turns a light yellow in color. The Satsumaimo are often longer and more slender tubers than other sweet potato varieties, boasting a mildly sweet flavor and soft, starchy flesh.


Seasons/Availability Satsumaimo sweet potatoes are available year-round with peak season in the fall and winter months.


Current Facts Sweet potatoes are botanically classified as Ipomoea batatas. Popular common names for Satsumaimo potato varieties include Beniaka, Beniazuma and Kintoki. The Satsumaimo is grown primarily in Kyushi, Japan and from there these sweet potatoes are shipped to the rest of Japan and around the world.


The Satsuma-imo is grown primarily in Kyushu, Japan, and from there the delicious sweet potatoes are shipped to the rest of Japan and around the world.

The only difference between that of a Satsuma-imo and an American sweet potato is that Satsuma-imos tend to have a milder flavor, softer flesh, and a lighter yellow coloring.

TIPS:
