Will have to look out for it! Also stationary is amazing in Japan. They have Pilot Friction erasable pens that erase perfectly and writes amazing. Its been popular there over 10 years and barely a blip here in the US. You can actually find them at depotmax.
Absolutely, Japan is great for stationary. I love the KuruToga mechanical pencils; these rotate the pencil lead some 30 degrees each time you lift the pencil from the paper. This means you always end up with a perfectly round tip and lines of equal thickness instead of the chisel tip you end up with normally.
I used to rotate my simpler mechanical pencils myself before I found these. Never going back.
