I do not know whether it is a studied affectation or just a habit--but the Prime Minister has a disconcerting way of staring slightly above and to the left of a person's head when he is trying not to appear bored.
You see it a lot when he is waiting for a reporter's question to end--or when others are speaking at public events where he himself is not required to speak.
This morning's Sankei Shimbun has a striking example of Abe lapsing into this "I must not look as bored as I feel" pose at the Kantei performance of Noel Paul Stookey's song for Yokota Megumi. Sadly, Sankei Web only offers a near cousin of the photograph.
I have to look for another example. A close approximation, but an engaged rather than bored version of the mannerism, can be seen in the campaign poster behind the PM in this photo.
