I found the front page of a manga on a JP blog that had "yandere" in its filename.
There was a link to its Amazon page on the blog too, so can anyone confirm?

That series is called "Yandere Kanojo".
Before you get excited, let me just say that the title is misleading. The title character is a yankee (delinquent) with more tsundere tendencies than anything else. Don't get me wrong, it's a good series, pretty funny, but if you were planning to read it exclusively to see an actual yandere character then you're out of luck.
