Hoku-hoku Yaki-imo

You know we are in the middle of autumn when you hear calls of ishi yaki-imo (sweet potatoes baked on hot stones​) ringing through the streets. That’s the sound of vendors driving trucks through residential areas to sell baked sweet potato​es. Harvested in September, and then after a period of storage to reduce excess water, now is when they are the most delicious. Not all imo are the same! Some are bright purple, while others have white skin. The hot, fluffy sweet potatoes known as naruto and benisatsuma are especially delicious.

In contrast, the silky sweet beniharuka variety from Kumamoto has a softer quality. Each variety has its own characteristics, so try a variety, and soon you’ll become a connoisseur. Recently, honey potatoes made from the sticky annoimo variety have become particularly popular, with customers falling for their moist, sweet texture and sugary flavor. Here are three recommended shops. But if it’s 4 am and you’re feeling the need, keep in mind that all Don Quixote (open 24 hrs) sell piping hot yaki-imo too.

Sweet Potatoes

At a glance it might appear that all sweet potatoes are the same, but there are many varieties! Each kind has a unique taste and texture. Give them a try and find your favorite!

Hokuhoku (Soft and Fluffy)
Beniazuma: A sweet potato typically used for roasting. This variety has a low fiber content, which means that it becomes soft and fluffy once baked. (Others: naruto, benisatsuma)

Slightly sweet with a soft texture. This variety is known for its light, refreshing aftertaste. (Beniharuka, silk sweet, etc.)

Animo (orange fleshed yams): Sweeter and more moist than most sweet potatoes. They have an almost sticky texture and are perfect for preparing yaki-imo.
