Initiatives for Employees̶ Reforming Human Resources System
toward the Next Century
Here at The Yokowo Group, we celebrated the 100th anniversary since ourfounding in September 2022, while at the same time we are embarking on
the next 100 yearsʼ journey.
As one part of our idea to “Be a good company” (see the p.17 “YokowoʼsMateriality”), the Yokowo Group has as our objective to “Be a company
where employees feel comfortable being employed, and which ensures that
employeesʼ families are happy for them to work there.”
In order that employees can feel good about the company, we feel that
as well as their achievements being recognized and them being satisfied
financially, their job satisfaction and sense of growth along with how they areachieving self-fulfillment are also important factors.
On the other hand, this rapidly changing and uncertain future meansthat existing frameworks are no longer as immediately applicable, and thatthe creation of new value is constantly required. And it is our people whowill create this value. This is achieved by each one of our diverse humanresources enhancing their own abilities, and combining them together.
This growth and self-realization of our employees is the source of thiscreation of new value, and an asset to the company. Looking forward, we
will promote a human resources system that can support active employee
growth, and that maximizes these abilities while achieving self-realization
for diverse human resources. At the same time, we will sublimate this intoa system that promotes the provision of opportunities that can lead to thecreation of new value (For specific efforts, see the p.43 “Employees”).

External Engagement Initiatives
̶ Toward External Assessment Responses
in ESG Management
As well as disclosing details of the measures taken to confront climatechange through the Carbon Disclosure Project (CDP) framework, an external
evaluation organization, the Group is aiming for a “B” rating, together withaiming to improve its rating with other ESG evaluation organizations. As one
part of our efforts in fiscal 2022, as well as publishing the Integrated Report,
we also expanded the content on our website and published a collection of
ESG data*. In addition to starting Scope 3 calculations for greenhouse gas
emissions, we will disclose detailed DEI (Diversity, Equity, and Inclusion) data
and update this as needed.
We were able through these initiatives to obtain an FTSE Russel ESG
rating of 3.2 (2.5 in previous year). We still have progress to make, but we are
steadily moving toward better evaluations.
The Group will strive to keep enhancing our corporate value as an evolving,
enduring company that continues to create something new for our customers.
At the same time, we will proactively confront new social issues on a global
level, and looking forward contribute to bringing about a sustainable society.
