Directions: take exit 3B from the Waseda metro station (Tozai line), and turn right out of the station exit. Go to the next big intersection, turn left (there's a huge red temple gate there, and a koban - you should walk on the same side of the street as the koban) It's just up the hill from there, on your right, across from Waseda University campus. It's about a three minute walk from the station.
