Do we go about our daily lives consciously aware of “vibration”?
Whether we’re riding in a car, inside a building, or watching children play in a park, we rarely notice anything amiss. That means the vibrations are being properly controlled.
If vibrations weren’t controlled, cars would rattle, buildings would feel unstable, and machinery would make unpleasant noises.
The technology that makes everyday life feel just right is vibration control using rubber.
A Kurashiki company that has supported people’s lives for many years with this technology is Kurashiki Kako Co., Ltd.
Because its work takes place out of sight, the company struggled to get people to know about it. So, in 2025, Kurashiki Kako Co., Ltd. launched the KURATECA brand to share technology developed in Kurashiki.
What is KURATECA, which is deeply woven into our daily lives? Here’s a closer look.
The information presented was current when this article was published in June 2026. Please note that it may differ from current information.
About Kurashiki Kako Co., Ltd.
Founded in 1964, Kurashiki Kako Co., Ltd. is a manufacturer specializing in anti-vibration rubber and vibration-control equipment.
Its business spans automotive parts as well as industrial machinery, semiconductor manufacturing equipment, railway vehicles, and aerospace-related fields.
Its strengths include vibration-control technologies such as anti-vibration technology that harnesses rubber’s elasticity and vibration-isolation technology based on the principles of noise cancellation. These technologies address everything from minute vibrations at the nanometer scale to large tremors such as earthquakes.
Out of sight, the company continues to support people’s safety and comfort.
When you don’t notice it, that’s proof it’s working properly
Kurashiki Kako makes products such as anti-vibration rubber and vibration-control equipment—products designed to reduce vibration.
Reducing vibration is not a role that draws attention. In fact, its purpose is to keep vibration from being felt.
For example, we don’t notice unpleasant vibrations or sounds while driving because various components suppress them. Kurashiki Kako makes nearly all the rubber parts in a car other than the tires, and its technology is used in about 38% of passenger cars sold in Japan (FY2024 results).
Yet we don’t think about it, because everything is working as it should. The fact that something is not unpleasant is actually proof of advanced technology.
A part of everyday life, found in parks and buildings
Kurashiki Kako’s vibration-control technology is found not only in cars, but also in places close to home.
Take playground equipment in parks, for example.
Small rubber parts fitted where metal components meet soften the impact when children play.
The company’s rubber products are also used in vibration-isolation platforms beneath air-conditioning equipment on the rooftops of large commercial facilities. Without them, vibrations and noise would travel throughout the building, making it difficult to spend time there comfortably.
In both cases, these products are almost entirely out of sight. Yet they reliably support our sense of security and comfort.
Unobtrusive, yet indispensable
That is the role of rubber products.
From minute vibrations to earthquake tremors: continually tackling vibration
Kurashiki Kako tackles more than just “shaking.”
Its work ranges from fields where minute vibrations at the nanometer scale affect quality, such as semiconductor manufacturing, to protecting buildings from earthquakes with a seismic intensity of 7.
The goal is not to eliminate vibration, but to make it comfortable for people.
Perhaps it is this perspective that allows Kurashiki Kako’s products to blend naturally into our lives and go unnoticed.
KURATECA, a new brand sharing technology developed in Kurashiki
The products and technologies introduced so far are woven into everyday life, making them particularly difficult for the general public to notice.
That’s why, in 2025, Kurashiki Kako launched its corporate brand, KURATECA, and began working to share technology developed in Kurashiki with the world. It is a new brand name created to help more people learn about the company and to bring its work to the world.
But the foundation remains unchanged.
Its products and technologies continue to support people by removing discomfort and anxiety from their daily lives.
We spoke with the company about its products and technological initiatives, and the ideas behind them.
