It's a shame someone more qualified than me hasn't written a review of this. Kuki is a fascinating figure in modern Japanese aesthetics, and this short book is fairly easy going, when he's not having implied discussions with Heidegger or trying to interest you in many, many, many different fabric patterns which may or may not have iki. The volume itself is very well done, with exhaustive notes, including images of those fabric patterns and explanations of Heidegger. What we badly need is a biography of Kuki, whose life was fascinating.
