Come see a piece of history at Japan's oldest stone arch bridge, a charming spot right in the heart of the city. When you look at just the right angle, the bridge and its reflection in the Nakashima River form a perfect pair of spectacles, which is how it got its name. Take a relaxing stroll along the riverbank, watch the koi swim by, and try to find the heart-shaped stone hidden in the wall—it's said to bring good luck in love!
