Our comprehensive support system covers the entirety of testing ― from test planning, through implementation, to reporting results.

Primary Service Offerings

Third-party testing service for websites and applications

Web Application Testing

The advantage of our testing service lies in the “third-party perspective” that objectively evaluates what users experience on your website and in your applications. This perspective allows us to identify the issues associated with a website or application’s design, user interface, functionality, and usability ― in order to enhance the product to become more intuitively usable. To achieve the most effective testing solution, we start by conducting extensive client interviews, from which our team of seasoned testing specialists builds our test plans and support tools that encompass the entire course of testing.

Why You Must Choose TOKO DS!

1. Proven track record in global (multinational) projects

The greatest advantage of choosing TOKO DS as your testing partner is our excellent capability in handling cross-border projects, particularly when introducing global systems into the Japanese market. That is why we are a preferred vendor for project managers in need of detailed quality checks prior to their product release in Japan. Our bilingual/bicultural staff smoothly handle meetings and report production, offering multilingual services for all aspects of the project.

2. Ingenious web usability enhancement know-how

Our long track record in usability testing attests to our ability in conducting website analysis, identifying problems, and in proposing solutions, based on our accumulated expertise. Even if a system displays text correctly, functions according to specifications, and provides all required content, it often needs improvement due to poor usability.

3. Maintained customer confidence resulting from 20 years of experience

TOKO DS is the IT service division of Toko Denki Seisakusho Co., Ltd., an ISO9001/13485-certified manufacturer specializing in medical and precision instruments. Initially formed as a printer testing department in 2002, TOKO DS has since expanded its service portfolio, which now includes testing services for a variety of IT devices (multifunction printers, mobile phones, audio-visual equipment, etc.), contributing to our customers’ product quality enhancement efforts. Our clientele includes several major global corporations. Fully leveraging our background as a manufacturer, we meet, with great flexibility and agility, the needs of project managers seeking a reliable outsourcing partner.

Are You Having Any of These Problems?

Our product needs a third-party evaluation, as testing based only on our internal knowledge may not be sufficient in terms of quality assurance.

 We are facing resource (personnel) shortages for testing that needs to be done immediately.

It’s hard to find a good partner company that offers comprehensive support.

We need people in Japan to handle meetings and reports in English.
