So the Moai in Shibuya is much harder to find than you would think.
It is, only around the corner from Hachiko, and right outside one of the exists of the train station, but somehow I managed to loop around quite a bit before finding it. =w=;;
It's somehow both bigger and smaller than I expected. The Japanese business man standing in from of it was kind enough to move when it looked like we wanted photos of it, although he looked a little mystified.
