A Little Backstory
Sweet potatoes didn’t start in Japan, they actually came from Central and South America. But they found their way to Japan in the 1600s, likely through China and Okinawa. Once they arrived, they became a lifesaver during tough times. They were easy to grow, didn’t mind poor soil, and could survive harsh weather.
During famines, especially in the Edo period, these potatoes fed entire communities. They were mostly grown in the Satsuma region (now Kagoshima), which is why they’re still called Satsumaimo—literally “potato from Satsuma.”
