What is their purpose in doing so?

It might seem “str.ange,” but the Japanese actually place these water bottles deliberately.

The Mysterious Water Bottles Lined Up Along Streets and Fences

If you’ve ever been to Japan or watched videos of its streets, you may have noticed something unusual in the quiet alleys of residential areas. Along fences, garden corners, next to plant pots, or at the edges of walls, you’ll often see transparent plastic water bottles neatly arranged.

At first glance, you might think someone simply forgot to put them away or didn’t clean up after a picnic. However, in reality, these bottles are deliberately placed – and the reason behind it is quite surprising. These bottles are not for drinking but are called “nekoyoke” – a tool used to “chase away cats.”

Japan is known for its deep love for animals, particularly cats. Cat cafes are widespread, and cats are even given important titles like principals or supervisors. However, stray cats are often not trained or properly cared for, which can pose risks like spreading diseases, damaging property, or even scratching and biting children or the elderly. Therefore, some families find ways to prevent strays from entering their homes. The practice of placing these “nekoyoke” water bottles has spread from this need.

This habit may seem puzzling to outsiders, but in Japanese cities, it is quite familiar. It represents an interesting blend of everyday logic, ancient beliefs, and practicality. While not ha.rmful to animals, people believe these water bottles help prevent stray cats from entering and making the area di.rty.

Although the reasoning behind this method has been questioned many times, the tradition continues to be maintained across generations, blending belief and habit. But the question remains: where did this odd habit start, and does it really work?

Where Did Nekoyoke Begin?

According to Indiatimes, the idea of using water bottles to deter animals didn’t originate in Japan. It actually came from the West, possibly from the 1980s in some European and American regions, where people placed water bottles on lawns to keep dogs away. Over time, this practice spread to Japan but was adapted for use against cats. Since Japan doesn’t have many stray dogs, people began using this method to keep stray cats out of gardens, walls, or in front of houses.

How Does It Work?

There are a few popular theories explaining why water bottles might repel cats. Some believe that sunlight or streetlights at night shining through the water bottles create surprising flashes of light that scare the cats.

Another theory is that cats see distorted reflections in the water bottles, which startles them.

Some also argue that the water bottle disrupts the cat’s perception of distance. Although none of these theories have been scientifically proven, the habit is still widely maintained.

Does This Method Really Work?

In reality – not necessarily. Studies and animal behavior experts suggest that there’s no clear evidence proving that water bottles effectively repel cats. On cloudy days or in areas lacking sufficient light, the light reflection effect almost doesn’t happen.

Nevertheless, many continue to place water bottles, partly out of habit and partly with the hope that “it’s better than nothing.”

Even if it doesn’t stop a curious cat, it remains a ha.rmless habit.

Today, the practice of placing “nekoyoke” water bottles is more of a cultural quirk than an effective solution. It reflects the neatness, creativity, and simplicity with which the Japanese approach everyday problems. Additionally, it adds to the charm of strolling through Japanese neighborhoods, making it a memorable experience.
