In order to realize a space that is comfortable, easy to use, safe and secure for everyone, the entire company is working together to create a better space. We also continue to take measures to improve quality technology, such as holding construction technology review meetings.
We provide "professional skill training for production staff" on "laws and regulations," "safety," and "construction" with the aim of improving the quality and skills of production staff. We also hold seminars for production staff with the aim of meeting customer needs and improving satisfaction by calling attention to safety and quality management at the planning stage and on-site.
We provide technical learning opportunities to review the key points of "design basics," "regulations," and "facilities" that designers and planners need to know in order to proceed with their work, and to avoid problems and risks from the design stage. In addition, we hold technical seminars for designers four times a year with the aim of strengthening their engineering skills.
As part of the training for new employees, we provide technical training programs on laws, regulations, prohibited matters, special management matters, electricity, machinery, etc. In addition, we are working to improve the technical skills of young employees by providing them with opportunities for construction consultations and on-site guidance on projects they are in charge of.
Before construction begins, we check the construction plan and safety plan, consider key management items and measures for prohibited items and special management items in terms of safety and quality, and hold "construction technology review meetings" with the aim of eliminating complaints, troubles, disasters and accidents and ensuring smooth construction. We strive to ensure quality by pointing out and extracting issues and problems in space creation, and by confirming laws and regulations, verifying structures and confirming construction methods.
At the monthly "Safety and Health Committee," we analyze and share claims and maintenance reports, and strive to prevent recurrence, as well as consolidate information on quality and technology improvement, and provide coordination, instructions, and guidance to the relevant departments. In addition, we have created a site on the company intranet dedicated to safety and quality that consolidates technical knowledge and information, and share information widely, and we also regularly review the "Safety Handbook."
Every year, we provide seven types of qualification training: special training in scaffolding assembly, special training in low-voltage electricity, training for scaffolding inspection practitioners, training for foremen and safety managers, training for general managers, training to improve the skills of foremen and safety managers, and special training in full harnesses. We have established a system in which not only approximately 450 production staff, but also technical partners and cooperating companies can take the courses, providing a wide range of educational opportunities to improve safety and quality.
Based on the Tanseisha Group Code of Conduct "6. Building relationships of trust with customers and space users" and the Environmental Consideration design item "Universal Design," we promote the creation of universal design spaces that are comfortable and easy to use for a wide range of users, including the elderly, children, people with disabilities, and foreigners.
In addition to universal design in terms of both soft and hard aspects, we strive to practice "universal design of the heart."
Since 2018, we have partnered with Mirairo Co., Ltd., a company that specializes in universal design consulting, to create facilities that incorporate universal design.
In addition, we have developed a multilingual app called "T-VOIX" that uses UV codes * to provide information translated into various languages in text and audio in offline environments, and we are working to have this app adopted by cultural facilities throughout Japan.
Additionally, we are continually collecting information about universal design and sharing it on our company intranet.
*UV Code: "Uni-Voice" is a voice code developed by the Japan Association for the Dissemination of Information for the Visually Impaired (JAVIS), a non-profit organization.
Examples of spaces that take universal design into consideration
"Ikei Pharmacy Yanaka Store"
Together with Mirairo Co., Ltd., a universal design consulting company, we carried out on-site surveys and verifications, aiming to create a space that took into consideration the width of the aisles, the wheelchair space in the waiting area, the dimensions and shape of the prescription counter, and the location of assistants. In addition, in the lobby, we placed bookshelves that also function as partitions at a height that can be easily used by people of all ages, from children to the elderly. In the sales corner, we also installed a counseling counter and beauty salon booths to help people become truly healthy.

Personnel Policy
We recognize that the diverse personalities and creativity of our employees are our most important management resources, and we respect their autonomy and individuality. Based on the recognition that employee health is the foundation for the expression of creativity and healthy growth, we will create a comfortable working environment that considers the health and safety of our employees. In order for our company to continue to be a professional and challenging group, we will provide opportunities for growth and support the growth of the team and the organization as a whole, aiming for each employee who is a member of the group to become a strong individual.
We respect the basic human rights of applicants and conduct fair recruitment selection based on the aptitude and ability of the applicant. Furthermore, through this recruitment selection process, we hire people who strongly empathize with our purpose and values, who are dedicated to achieving them, and who strive to become and continue to be the type of people we desire.
Based on the idea that work develops people, we respect and support the desire of our employees to learn and grow. We base our human resource development on diverse work experiences and OJT, and support growth through visualization of skills and experience, placement and rotation, and OFF-JT education and training. We also support employees' autonomous career development.
To help people learn about and deepen their understanding of diversity, we have been conducting training for all executives and employees since 2017, and from 2021 we have been conducting training for managers who play an important role in human resource development and management.
In addition to deepening understanding of diversity, participants will be able to learn and become aware of many things related to work and working styles, which will help foster a corporate culture that responds to diversity and accepts diverse working styles.
In order to improve the employment environment so that women can play an active role, we have formulated and are implementing an action plan based on the Act on Promotion of Women's Participation and Advancement in the Workplace. We have set targets for the ratio of women in management positions, and are implementing career training programs, as well as promoting the acquisition of childcare leave, including for men.
In 2023, we received two stars (level 2) of the "Elboshi Certification" as a company with an excellent record of implementing initiatives to promote women's participation in the workforce.
General employer action plan based on the Act on Promotion of Women's Participation and Advancement in the Workplace
In order to create an employment environment in which women can thrive, we have formulated the following action plan.
In order to create a workplace environment that is easy for hearing-impaired employees to work in, we have introduced the corporate version of the communication support and conversation visualization app "UD Talk®," and we also use sign language interpreters. We are also working to foster an inclusive organizational culture by sharing and providing consultation on methods and procedures for ensuring information access on our in-house portal site, and holding in-house social events using sign language to facilitate smoother work-related communication between hearing-impaired employees and other departments.
We plan and implement educational and training programs both inside and outside the company so that new employees, as well as young employees, mid-career employees, and managers, can acquire the skills required for each level and job type as "spatial creation professionals." We also support the career development of our employees by holding career interviews to encourage their growth as managers and professionals.
We also provide evaluator training for managers with the aim of understanding the capabilities of individual creators and providing appropriate career support.
We support each employee's independent learning and aim to develop highly specialized human resources. As part of this, we have established a qualification support system for first-class architects, first-class construction management engineers, and other qualifications that are legally required or deemed necessary for the job, and we support employees in obtaining qualifications by paying a portion of the expenses associated with obtaining them.
1st class architect, 2nd class architect, 1st class structural design architect, 1st class Equipment Layout architect, building facility engineer, 1st class construction management engineer, 1st class construction management engineer assistant, 2nd class Building Work management engineer, 2nd class Building Work management engineer assistant, supervising engineer, real estate agent, curator, 1st and 2nd class event management specialist, small and medium-sized enterprise consultant, managing architect, outdoor advertising specialist, construction accountant, electrical and electronics general technical supervision, specially managed industrial waste management manager, safety manager, 1st class sanitation manager, fire prevention manager, safe driving manager, manager to prevent unreasonable demands, waste management manager, etc.
In order to strengthen our creative capabilities, we hold in-house seminars and "creative salons." In addition, we disseminate and share information for various research purposes, such as design knowledge, know-how, and materials, and we also invite top creators from outside the company to hold seminars and training sessions at our head office and in VR.
We have been conducting our original practical training for new recruits, the "Human Resources Development Project," since 2005. This training consists of "Introductory Training" and "Business Handbook," which allow new recruits to get to know the company and learn the basic knowledge necessary for business operations, and "Product Creation," which allows new recruits to put manufacturing into practice.
The core program of this training, "Product Production," aims for new recruits to work in teams while experiencing various difficulties through actual manufacturing, gaining basic knowledge according to the characteristics of the job, and preparing for practical work after being assigned. Through consensus building and relationship building with stakeholders, and managing quality, costs, and delivery dates, new recruits experience difficulties similar to those encountered in the workplace, overcoming them as if they were their own problem, and seeing the product through to completion, thereby gaining their first experience of success. At the exhibitions that have been held since 2011, new recruits are able to showcase their learning and growth through products created together with leading designers and first-class craftsmen, while also conveying the company's attitude and commitment to developing its employees.

In addition to the "telework system" and "flextime system" that allows employees to freely decide their working hours for all employees, we have introduced a short-time work system that is not based on childcare or nursing care reasons, and aim to improve productivity and well-being by promoting work-life balance. In addition, we are taking measures such as introducing sick leave and infertility treatment leave so that capable and motivated employees can balance their work with their family and private lives and choose various working styles, creating a workplace where diverse human resources can work comfortably and demonstrate their abilities, and promoting work style reform.
Childcare and nursing care support
We are working on improving our system to increase the rate of employees taking childcare leave, shortening working hours for employees who are raising children, encouraging employees to take annual paid leave, and partnering with company-run daycare centers. We have also established a "Family Friendly Promotion Committee" with the aim of supporting the development of the next generation, and are working to promote activities that allow for diverse work styles through support such as setting up a consultation desk for childcare and elderly care and holding elderly care seminars. In 2007, we obtained the next-generation certification mark (nicknamed "Kurumin").
General employer action plan based on the Act on Advancement of Measures to Support the Development of the Next Generation
In order to provide an environment in which employees can demonstrate their capabilities and work comfortably while achieving a good work-life balance, we have formulated the following action plan.
We have set a goal of reducing long working hours and are working across the company to achieve it. We have also established a Work Style Reform Promotion Committee to review work styles and the office environment.
In order to streamline operations and improve productivity, we are providing employees with work devices that match their working styles, as well as improving our IT environment by introducing RPA (Robotic Process Automation) and AI chatbots, and digitizing and going paperless for purchasing transactions and internal application documents and procedures.
With the aim of streamlining our internal business processes, we are also working to utilize unique digital tools tailored to each job type and task, such as expanding our dedicated information database for production positions and introducing a document creation navigation system.
We are creating offices that take into consideration productivity improvement and well-being in line with new ways of working. In the head office office update, we added more facilities for mental, physical and social health, such as a space for relaxation and communication, massage space and play zone (ping pong table and putting mat). We have set up a "distributed network office" to increase contact points between employees without dispersing people. In addition, from the perspective of improving productivity and risk management, we are increasing the options for places to work other than the head office, branch offices, sales offices and home, such as using external shared offices and opening a Yokohama satellite. In addition, we have introduced a free address system at the head office and each branch office, and are improving the office environment by installing web booths that can be used as simple changing rooms as part of our consideration for privacy.
Through "Work Style Reform NOW," a regular message from the president sent out within the company, we inform employees of the importance of health, as well as the importance of correcting long working hours and being conscious of how we use our time, which are the foundation of health.
We have established a "Health Management Department" as a dedicated department for health promotion, and in addition to providing education to raise awareness and responding to incidents, we are implementing company-wide measures by sharing current data and information. By early detection of mental and physical disorders that can occur to anyone and careful follow-up according to the situation, we are contributing to maintaining the social health of the entire organization.
In addition to conducting regular health checkups and stress checks based on the Industrial Safety and Health Act, we also provide comprehensive medical checkups, women's health checkups to prevent diseases specific to women, influenza vaccinations, interviews with industrial physicians, online counseling, etc. In addition to holding "self-care training" for all employees and "line care training" for managers, we are also working to raise employee awareness by visualizing vacation acquisition status in real time, which will lead to promoting vacation acquisition.
We have introduced Group Long-Term Disability Insurance (GLTD) and Group Medical Insurance as employee benefit programs to protect the lives of employees and their families from unforeseen work-related disabilities, allowing them to focus on recovery with peace of mind and support their early return to work.
Tanseisha has been conducting employee opinion surveys every two years since 2016. We consider this survey important in order to continue being a "good company" that balances "employee happiness at work" with "high performance" and to become an even better company. Based on the survey results, we link them to environmental improvement activities for the whole company and each department. In addition, with the aim of strengthening communication between employees and improving engagement, we also promote communication with employees' families by publishing the in-house newsletter "TANSEI-zine" and holding family days where employees' families can tour the office.
In order to improve engagement across the entire group, we hold a walking event called "Tansei Telewalk" using a pedometer app, hold joint induction ceremonies and training for new recruits, and proactively disseminate information within the company and to group companies. Furthermore, we hold an annual awards ceremony to recognize the work performance and results of employees, including those in group companies, and outstanding design activities.

Since 2011, we have been participating in the "Art and Sign Language Project," which aims to create an environment where various people can connect loosely and enjoy art appreciation with the keywords "art," "museum," "sign language," and "people who are deaf or hard of hearing." Since 2021, one of our employees has served as the representative, and has been planning and implementing appreciation tours and workshops with art museums and organizations across the country.

Since 2021, we have been cooperating on the event ``Super Welfare School @ SHIBUYA,'' which broadcasts concrete actions and the latest examples related to education, lifelong learning, learning, working, etc. from all over the country offline and online from Shibuya, and in 2023 we co-hosted the event and spoke at a symposium.
"Super Welfare School @ SHIBUYA" is being held as one of the "After Super Welfare Exhibition" projects of the "Super Welfare Exhibition (official name: 2020, Shibuya. Let's Experience the Daily Life of Super Welfare Exhibition)" which has been held for one week in November every year since 2014 mainly at Shibuya Hikarie in an effort to remove "mental barriers" against minorities such as people with disabilities and welfare itself. Our company has been cooperating with the Super Welfare Exhibition since 2014, and co-hosted it with the NPO People Design Institute for five years from 2017 to 2021.
