Japan System Techniques Co., Ltd. (Head office: Osaka, Representative: Takeaki Hirabayashi, President and CEO; JAST)
and YARUKA YARANKA Inc.*1 (Head office: Kashihara-shi, Nara, Representative: Natsuki Nishi) are working together
since December 2022 for the provision of services that reflect the needs of generation Z students *2. YARUKA YARANKA isa start-up company managed by Natsuki Nishi, who is a student at Kindai University in the master’s degree course fortransdisciplinary graduate school of social innovation and entrepreneurship.
One result of this collaboration is the use of the know-how of both companies to develop MiraThin, which is an app thatenables generation Z students to use AI for determining a suitable career path. Closed beta testing of this app started on March13, 2024.
The main business of JAST is B-to-B operations involving the provision by companies of systems and services to universities.
Adding this service will expand JAST’s operations to include B-to-C businesses for the provision by companies of systems
and services directly to consumers. This will allow JAST to supply systems that even more closely match the requirements ofstudents who are the end users of UNIVERSAL PASSPORT *3.
Kindai University gives students opportunities to become involved with various industries as an institution with a commitment
to practical education. In addition, the university places a high priority on supporting student entrepreneurs. This collaboration

The MiraThin AI Career Path Determination App

The MiraThin app uses AI to ask students numerous questions to perform an automatic career path diagnosis. For example,students may be asked about the type of person they want to become, the careers interest them most and specific jobs thatappeal to them. Answers are used to generate 15 potential career paths. In addition, the student enters information aboutcareers that interest them. Based on all of this information, this AI service with an interview format provides advice about asuitable career path in order to enable students to discover new options.

The MiraThin System

The system used for MiraThin is based on the amplification of Amazon Web Services (AWS). The front end was developedby using a serverless and modern environment that utilizes Next.js. As a result, the strength of using the cloud can be used
for auto scale (automatic increase/decrease of cloud servers to match changes in the server load) and agile (a codedevelopment method that uses a repetitive cycle of small, incremental tests) updates. The result is a flexible structure that canbe successively improved as the system operates. The user interface is another priority. The app features a futuristic designthat appeals to generation Z and an intuitive user interface design. Results of the career path diagnosis are generated by using
an algorithm incorporating psychological elements and text created by the generative AI of OpenAI. Students’ replies andareas of interest are analyzed to create proposals for the next steps students should take. For example, MiraThin tells students
about job categories where specific capabilities can be used most effectively and identifies skills that should be upgraded toreceive the greatest possible benefits. As a result, MiraThin is a career path determination system that can produce
recommendations that are even closer to the characteristics and goals of each user than the conclusions of conventional webbased applications are.

Upcoming Activities

JAST and YARUKA YARANKA plan to start closed beta testing by using students at Kansai area universities, chiefly Kindai
University. Data obtained from these tests will be used for the full-scale launch of this app, which is to take place in 2024.
This development project is using the lean startup methodology with operations performed mainly by generation Z creators.
By aiming to create a product with the minimum capabilities needed in order to reduce expenses and shorten development
time, this methodology determines goals by repeatedly confirming customer feedback. This approach enables a business tooperate with no wasted use of time or resources. In the conventional waterfall software development methodology, thedevelopment process goes from upstream to downstream stages. When using this approach, the final product is created after
repeatedly receiving feedback from users in order to incorporate that information in the product. As activities leading up to
the official launch of this app continue, JAST and YARUKA YARANKA will continue to strengthen the framework for joint
activities.
JAST will continue to use technologies and knowledge acquired since its inception 50 years ago to provide assistance tostudents and young entrepreneurs. By thoroughly examining a broad range of issues in various markets, JAST is determined
to continue the “co-creation digital transformation” process backed by the launch of new services and the co-creation of valuewith customers.
