Japan's Peanut Butter

I recently tried peanut butter spread after a long abstinence period. Guess, what, the Japanese version of peanut butter taste nothing like what I was used to in Malaysia. Frankly, I do not dislike it, but it's just different. The non-chunky version of it tastes like kaya in syrup. Here's a picture of the peanut butter that I am talking about. See, even the texture look's like kaya.
