Review: I Taste The Okinawa Purple Sweet Potato Kit Kat!

When I first saw the Okinawa Purple Sweet Potato Kit Kat, I assumed that it was ube or taro but I later learned that it’s a different kind of starch.

What is purple sweet potato?

First I should point out, purple sweet potato often has the name “Okinawa” or “Hawaiian” attached to them because that is where they are commonly found. The difference between ube and purple sweet potato is that ube is a yam with an off white beige color to the skin while Okinawa purple sweet potato has purple skin AS WELL as some have light brown color to its skin, similar to a regular potato. The “meat” of ube is a light purple that turns dark purple when cooked, while Okinawa purple sweet potato has purple “meat” when it’s raw.

These 2 aren’t the only starches many people get confused when identifying. People confuse these with taro, other purple sweet potatoes and yams as well. Their flavors and textures can differ slightly but noticeable if you ever try to cook with them.

You can learn more about Japanese Kit Kat on their website!


I bought this at Fukuoka Airport before I left Japan.

You can find these in any souvenir shop or places like Don Quijote for a lot cheaper.

You can find it at most airports but they will be more expensive.


This cost me $800 YEN = about $7.05USD.

At Don Quijote it was $500 YEN Tax Free.

So definitely plan ahead to save money when you’re shopping.

I couldn’t smell anything when I first opened it so I was a little skeptical. However, I was immediately impressed when I first tasted it. The flavor was great! ٩(♡ε♡)۶

The Kit Kat tasted like a sweet blueberry flavor but slightly tart, like a blueberry pie.

Personally, I really enjoyed it. There was something about it that made me want to have another. The flavor is familiar and yet new.

Would I buy the Okinawa Purple Potato Kit Kat again? YES!i

I usually don’t like buying packets of candy because I rarely eat the whole pack. I’m more of a pastry person but it was worth buying the larger pack because I was able to enjoy these more thoroughly.
