What is Yakiimo?
Yakiimo or Baked Sweet Potatoes is a mouth-watering baked Japanese sweet potato snack, especially popular during the colder seasons in Japan.

Yakiimo History
The origins of roasted sweet potatoes may be traced back to the Edo era. To bake the sweet potato, they placed the charcoal in a waist-high jar, and heated the air within the jar. Manzo Minowa devised the stone-baked sweet potato, which is baked on a hot stone in a kiln, after the war in 1951. When opposed to the pot-baked method previously utilized, stone-roasted potatoes can cook a significant volume in a short amount of time. In addition, Mr Minowa leveraged his past expertise working at a ramen shop to sell a set of tools for creating stone-baked sweet potatoes on a cart.
Baked sweet potatoes, which first debuted in the late Edo era and are still popular today, have experienced three booms so far, and the fourth is already quietly started. When the first baked sweet potato boom happened in the late Edo era, inexpensive and sweet baked sweet potatoes were the “jusanri, sweeter than chestnuts,” and a baked sweet potato boom arose. The second boom occurred during the Meiji era, when Tokyo’s population surged. It gained attention as a cheap dish, and it grew in popularity, resulting in the establishment of several stores that also operated as shaved ice shops during the summer.

Manzo Minowa of Mukaishima, Sumida Ward, began selling stone-baked sweet potatoes from a cart in postwar Tokyo, and stone-baked sweet potatoes spread quickly in downtown neighborhoods like as Asakusa and Fukagawa. The sale of stone-baked sweet potatoes peaked during the 1960s time of tremendous economic expansion. However, following the Osaka Expo in the 1970s, fast food restaurants and convenience stores proliferated, and sales of stone-baked sweet potatoes dropped. These days Japanese now offered them in supermarkets during the winter, and it is simple to obtain stone-baked potato cooking gear and tools online, so the old-fashioned stone-baked potato auction has all but vanished.
