Taro
Japanese Taro
noun
A hometown potato is a taro. In Japan, taro is the kind of potato that everyone has in their hometown, because it's been around for such a long time and it'll grow anywhere.
In English, "taro" can sometimes be used for other root vegetables too, but just keep in mind this word refers specifically to the Japanese taro — a small, starchy, potato-like vegetable.
This is a jukugo word that uses the kun'yomi readings of the kanji.
