The analysis below might be overthinking it a little, but I’ve got to agree with the bigger idea: this, like pretty much everything Muji makes, is made from at least 50% post-consumer awesome.
The Muji Chronotebook
I love this concept—a sort of open-ended day planner. Rather than constraining you into a certain way of planning your time, Muji’s Chronotebook simply has a small clock graphic in the center of every page, leaving room for the user to develop whatever system they like to organize their day. This product is a great example, in many ways, of the benefits of the “worse is better” school of design—the simpler and more general a product design is, the more free the end user is to evolve their own uses for it, many of which could not be anticipated by the designer (other great examples I like to point to: del.icio.us, Twitter, and the HTTP protocol’s “rule of least power”).
