고구마

A sweet potato depicted with textured purple, orange, or brown skin and sliced in half to show its golden-brown flesh. Sometimes called a yam, though they are unrelated. Not to be confused with the Potato.

Commonly roasted as a snack in East Asia during winter, much as squash and pumpkin are popular in the United States during fall/autumn. Used as an offering to the full moon in Japan during the Moon Viewing harvest festival.
