My name is Tsukasa Sakurada, and I am the CEO of Susumé Co., Ltd.

​

We are a startup venture company aiming to create a society free from the spread of infectious diseases.

In the past, the only infectious disease successfully controlled by human intervention was smallpox. As you know, with the current coronavirus, countermeasures have been extremely limited, consisting of handwashing, alcohol disinfection, and masks.

​

In 2008, the US EPA approved copper alloys as a sustained-release disinfectant. In the US, the Copper Development Association, under the International Copper Association, was the first in the world to statistically demonstrate that infectious diseases can be prevented through the sustained disinfection of copper alloys. While many papers exist, practical application has been hampered by issues such as versatility, cost, and discoloration.

With the support of JETRO and US universities, we have developed "AbedulAg+", a sustained-release disinfectant made from ceramic composite materials that overcomes the challenges of copper alloys. We have confirmed that it maintains a 99.9% disinfecting effect on textile products after 300 washes.
