[History]
It is said to have originated on the shores of Lake Titicaca in the Andes of South America.
It reached Europe around the 15th–16th centuries.
It was introduced to Japan from Java by the Dutch (or by merchant ships).
There are several theories about the year of introduction, but it was around 1600.
Later, in the 18th century, it came to be cultivated as a famine relief crop.
From the Meiji era onward, with the introduction of superior varieties, it came to be cultivated in earnest.
