System integrator Tokyo System House Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo; Representative Director: Tomoyuki Hayashi; hereinafter 'the Company') has been promoting internal communication measures tailored to diversifying work styles since 2023. Through these initiatives, the retention rate for new graduate employees has been maintained at over 90% for the past three years. This is the result of implementing communication measures such as the employee-led exchange initiative '○○-kai Support,' aimed at revitalizing communication among employees.
*○○-kai Support: Read as 'Marumaru-kai Support'.
■ Background
Against the backdrop of diversifying work styles, such as an increase in mid-career hires, client-site assignments, and telework, the Company launched the 'Communication Promotion' team within the Corporate Planning Office in 2023 to foster internal communication.
The team plans events 12 times a year where employees can interact with each other. Emphasizing that 'initiatives should not be limited to only some employees' and 'the design should allow for natural participation without coercion,' the team has organized sports days and open offices (family invitation events), aiming to create an environment where all employees can have a point of contact somewhere.
On the other hand, with the diversification of employee values, it became a challenge to provide uniformly attractive events to all employees. Therefore, as a new initiative to create opportunities for exchange driven by employees themselves, the '○○-kai Support' was launched and has now been held for the 4th time.
■ About '○○-kai Support'
'○○-kai Support' is an initiative where the company supports cross-departmental networking among employees, such as peer group meetings, girls' gatherings, and hobby groups. Its feature is that employees can independently plan and freely participate. This time, 27 diverse plans were implemented, including 'Wanko Soba Challenge Group,' 'Eel Appreciation Group,' and 'Ski/Snowboard Group,' with a total of approximately 190 employees participating.
Natural interactions are born when employees with similar interests and concerns gather, leading to the strengthening of cross-departmental ties. Furthermore, by making 'participation by 3 or more employees from different departments' a condition, it promotes cross-organizational communication.
[Outline of the Initiative]
- Support up to 3 times, with a maximum of 3,000 yen per person
- Participation of 3 or more employees from different departments
- Advance application system
Through this initiative, the Company is creating opportunities for interaction among employees who have little contact in their daily duties, thereby revitalizing internal communication.
■ Effects and Future Outlook
We believe that maintaining the retention rate of new graduate employees is not due to a specific measure, but the accumulation of multiple initiatives, such as employee growth support and communication measures. As a result of these efforts, the Company has maintained a stable level in the retention rate of new graduates.
[Retention Status of New Graduate Employees]
- 2025: 7 hired / 0 left (Retention rate 100%)
- 2024: 9 hired / 0 left (Retention rate 100%)
- 2023: 11 hired / 1 left (Retention rate 90.9%)
Moving forward, the Company will continue employee-led initiatives, including '○○-kai Support,' to strengthen the bonds between employees and promote the creation of an environment where they can continue working with peace of mind.
