How to get there:
•At Ocahanomizu Station, go out the Ochanomizubashi exit.
•Turn right, cross the bridge.
•Keep going straight, up the yellow brick ramp (or stairs) to the hospital. Follow the outside walkway around to the right, and make your way (outside) through the hospital complex.
•When you arrive at the street on the other side of the block, look to the left and across the street. There is a huge hotel there with an entrance covered by a big bulge of the curving brick facade. Cross the street and go down the little alleyway to the right of the hotel.
•At the end of the alleyway, where it intersects the street on the other side of the block, the store on the left-hand corner is the Origami Kaikan (Origami Center) Building.
