When you visit Kyoto Japan, You can see find them at Kiyomizu-dera temple "清水寺" and Kyoto Imperial Palace "京都御所". We have brushed up the technology that has been a long-standing tradition and applied it to the production of Shinobi Gaeshi. Our Shinobi gaeshi is designed to match not only traditional Japanese architecture, but also modern Western architecture as you can see this website.
What is SHINOBI GAESHI?
In Japan, security spikes are called "Shinobi Gaeshi 忍び返し", which means literally “Ninja Deterrent™” in Japanese. The origin of "Shinobi Gaeshi" dates back to the era of Ninjas ”忍”. These spikes were used to prevent Ninjas from entering buildings and attacking the occupants.
More recently, Shinobi Gaeshi are used to secure homes and facilities from unwanted intruders particularly in the high-end home market. Additionally, they also have been installed as barriers to prevent animals from entering properties and from birds from perching on screen walls or security fences.
Our high quality, durable, and well designed "Ninja Deterrant™" helps prevent any unwanted intruders such as thiefs, cats, birds, and the occasional Ninja "忍".
