If you are a beginner for Japanese desserts and not so sure about jumping into sweet red bean paste concoctions, Green Tea Cookies might be the perfect place to start.  Most people are familiar with western-style cookies, and this is certainly in the same family.  It just has less butter and more flour (two different kinds, cake flour and cornstarch).  Because of that, the texture of the cookies is more powdery, and the texture might be a little different from what you are used to.  Also it’s not overly sweet.  Nonetheless, it tastes good (and Japanese)!
