Japanese Sweet Potato Varieties

Japanese sweet potatoes are often grouped into two main types:

Rich & Creamy type: These sweet potatoes are moist and silky with a high natural sugar content. They’re ideal for roasting (yakiimo) or making desserts.
Flaky & Soft type: These sweet potatoes are light, fluffy, and starchy. They’re perfect for soups, tempura, or other savory dishes.

Let’s take a look at some of the most popular varieties you can find in Japan.

For yaki imo, Annou Imo and Beni Haruka are perfect. They’re naturally high in sugar and become rich and honey-like when baked. If you prefer something a bit milder, try Silk Sweet for its smooth texture and elegant sweetness. Check out my full guide: Yaki Imo Taste Test: 7 Sweet Potatoes Compared.
For tempura or soups, the flaky type, such as Beni Azuma and Naruto Kintoki, works well.

How To Pick Delicious Sweet Potatoes

Choose plump, round sweet potatoes with smooth, bright skin. They tend to have a softer texture and taste sweeter when cooked.
Pick ones that feel heavy and firm when you hold them. That’s a good sign they’re full of moisture inside.
Look for a small dried black spot near the ends. It’s a sign of natural sugar. Sweeter potatoes often have this mark.
