Sweet potato rice, or Satsumaimo Gohan, is a popular dish in autumn. It is made by cooking satsumaimo or Japanese sweet potato and rice for slightly sweetened rice. The natural sweetness of the satsumaimo with the rice makes it a great standalone meal or can complement any other dish. If you like Japanese sweet potatoes, this is a dish you have to try. This post is about easily making sweet potato rice or satsumaimo Gohan at home with a few ingredients.

Ingredients for Sweet Potato Rice
- Japanese short grain rice – typically, Japanese short grain rice is used in most Japanese dishes. It is a sticky rice type that perfectly matches the dense, nutty sweet potato. If you want stickier rice, you can combine mochigome, rice used to make mochi.
- Japanese sweet potato – Japanese sweet potato is the key ingredient in this recipe. This type of sweet potato is mildly sweet and nutty with a chestnut-like texture.
- Cooking sake – adding sake to rice helps bring out the rice flavors. It makes a slight difference in the taste. However, you can omit it if you do not have it or do not want to use it.
- Mirin – mirin is a type of sweet sake. It adds a little extra sweetness and flavor to the dish.
- Pinch of salt – this helps bring out the sweetness of the satsumaimo even more
