Japanese Kit Kat Onsen Manju Flavor Chocolate

Today when I went out shopping, I stopped by a supermarket and came across a rare Kit Kat by chance that had been sold only in Japan’s Onsen hot spring resorts in 2018.

That Kit Kat flavor is “Onsen Manju (温泉饅頭)” flavor, which seems to have been renewed recently and re-released for a limited time only.

I got this Kit Kat Mini Onsen Manju chocolate for 258 yen (about 2.5 USD). On the package front, you can see illustrated Onsen Manju, together with the drawing of a cute monkey soaking in the open-air bath. 

What is Onsen Manju?

For the unfamiliar with Japanese food, “Manju (饅頭)” is a traditional Japanese sweet consisting of a soft, fluffy steamed bun filled with sweet red bean paste called “Anko (餡子)”. 

The confection comes in several different varieties, and the one sold in hot spring resorts is generally called Onsen Manju.

Now, let’s get down to the main topic. So the white chocolate exterior of this Kit Kat is flavored with a flavoring that recreates the taste of Onsen Manju.

Meanwhile, the interior is filled with crispy wafers mixed with Koshi-An (a type of Anko, smooth Azuki red bean paste) cream. 

Overall, the bar is like a fusion of a Western chocolate snack and a Wagashi confection. The combination creates a great harmony, making this Kit Kat unlike any other.
