The best know Japanese smart card is SUICA, launched 12 years ago by the JR East. The JR West version is called ICOCA and it was launched... 10 years ago today! ICOCA is always impersonated by its mascot Ico the Platypus (Kamonohashi no Iko-chan in Japanese), thus being very easy to spot its charging stations - like in the billboard from today's photo.
So, Happy Anniversary Iko-chan, and for more travel tips, I recommend you to visit the Travel section of the new GaijinPot website.
