Astemo, the manufacturer of TOKICO products, was established in January 2021 as a new company through the merger of Hitachi Automotive Systems, KEIHIN, SHOWA, and NISSIN.
Since our establishment, our shock absorbers for 2-wheeled and 4-wheeled vehicles (mass production vehicles and aftermarket) have been highly evaluated by customers worldwide.
We have been pursuing high performance in all our products and pushing the limits of technology.
Our staff in the development, production, and quality sectors are working to create products that are of high quality and high functionality.
As part of this effort, we have supplied products to numerous races for both motorbikes and cars where every 1/1000 of a second counts, and our technical capabilities have been proven through activities that have led to title wins.
TOKICO shock absorbers, which integrate these technologies, are provided to customers from Astemo's worldwide service network with a sense of security and safety.


Astemo consistently strives for perfection with its sophisticated drive control systems. Struts are an integral part of your vehicles handling. TOKICO shocks and struts are designed and tested to support the vehicle weight, while providing the smooth handling in various road conditions. TOKICO shocks consists of a piston in a sealed tube filled with gas and/or liquid. When vehicle hits a bump, the shock is meant to absorb that impact so you don't have to while keeping your wheels in constant contact with the road. Our high performance shocks and struts are made for consumers who prefer smooth handling of their vehicles.
