DAIGAKU IMO: The Sweet Potato with a College Education

大学芋 Daigaku Imo​

While growing up in New York, I took lessons at The Art Student’s League on Saturday mornings. After class I would meet my father for a late lunch. His office was a few doors down from the Plaza Hotel (where Eloise had taken up residence in 1955) in the building next to Prexy’s. The burger chain’s slogan was “the hamburger with a college education” and their logo featured a nerdy-looking burger wearing glasses and mortarboard graduation cap.

Fast forward to the 1960’s when shortly after arriving in Japan I discovered the sweet pleasures of daigaku imo. Curious about the origins of college-educated potatoes (daigaku = college or university and imo = potato), I was told it was the favorite snack of Japanese university students in the early part of the 20th century. Although a few sources suggested a connection to Waseda University, most credited Tokyo University (Todai) as the elite institution responsible for daigaku imo’s popularity. Mikawaya, a yaki imo (stone-roasted sweet potato) vendor in front of Todai’s red-gate entrance was probably the first to glaze fried sweet potatoes with sugar.

Interestingly in Osaka a similar sweet potato snack is called Chūka Poteito implying the true origin of the dish to be Chinese. Indeed there is a Japanese publication dated Meiji 45 (1912) called “Practical Chinese Cooking Techniques” that introduces a lard-fried, sugar syrup-stewed sweet potato snack, minus the black sesame seeds. This Chinese version is still served today in many restaurants in both Kobe’s and Yokohama’s Chinatown.
