Why are couples along the Kamo River always sitting evenly spaced?

If you walk along the banks of the Kamo River in Kyoto, especially between Sanjo and Gojo bridges, you’ll notice a funny yet charming pattern: couples and friends sit in neat lines, spaced out like dots on a grid. It almost looks choreographed—but it’s not! This phenomenon is often joked about on social media, but it's actually a reflection of Japanese social manners. People tend to respect each other's space, even in public places. In Kyoto, where tradition and subtlety are valued, this habit is especially visible. Some say it's because couples want privacy while still enjoying the same romantic view. Others believe it’s an unspoken rule passed down through generations. Whatever the reason, it’s become a kind of “living artwork” that both locals and tourists enjoy watching. So next time you’re in Kyoto, take a walk along the river and see for yourself—it’s one of the city’s quietest quirks.
