The Journey to Improved Workplace Safety with MEDIAID Insoles at Toyota Battery

Japan Sigmax Corporation, based in Shinjuku, Tokyo, has created a significant impact in the work environment with their dedicated brand "MEDIAID." The company specializes in support products aimed at reducing fatigue for workers, specifically with their innovative insoles, the "MEDIAID Assist Insole Arch & Grip." This insoles' implementation in the manufacturing sector of Toyota Battery has made waves, addressing the challenges posed by safety shoes in the workplace and enhancing the safety and comfort of employees.

Overview of Toyota Battery Corporation

Their product lineup includes nickel-metal hydride batteries, lithium-ion batteries, and Battery Management Systems (BMS). They even conduct contract testing for vehicle battery packs. The excellence of their technology supports the electrification efforts of Toyota and numerous electric vehicles worldwide.

Manufacturing Women’s Initiatives: Empowering Female Employees in Safety

In spring 2025, during labor negotiations, female employees in the manufacturing sector voiced concerns over career progression, highlighting a lack of female role models and a predominantly male workforce culture. This led to the initiation of the manufacturing women’s initiative, driven by the desire to create a better work environment. Eighteen women formed three teams to address themes related to challenges in protective gear, female-specific concerns, workplace environment, and organizational culture, identifying safety shoes as a significant issue under protective gear.

The Challenge: Safety Shoes that Weigh Down Instead of Protecting

In manufacturing, prolonged standing is commonplace, leading to excess stress on the feet. While safety shoes are designed to protect against falling objects, their stiffness and weight can conversely cause discomfort and fatigue. Many employees reported various foot-related issues, such as pain in the soles, heel discomfort, and swelling from prolonged wear or improper fit, leading to challenges like tripping—a serious safety risk in high-stakes environments.

The Improvement Process: Collaboration between Manufacturing Women's Initiative and Safety Promotion

Responding to feedback about foot strain, the initiative began assessing if they could improve safety shoes. However, safety standards often limited the ability to alter footwear—making it challenging to find a suitable solution. Fortunately, during discussions, both the manufacturing women's team and the safety promotion office realized they were tackling the same issue. This discovery accelerated their collaboration.

As part of an initial rollout, an on-site trial of the new insoles began, where employees tested them for two weeks, gaining insights through meetings on the insoles' effectiveness in alleviating discomfort. The positive feedback paved the way for widespread acceptance and consensus among the staff.

Results of the Insole Trial: Immediate Positive Outcomes

The initial findings were promising. Employees reported decreased discomfort and improved foot condition after just a few days of use. Some noted that their swelling from standing all day had significantly reduced. The results from a broader pool of employees also confirmed an increased ease in walking and diminished tripping incidents, with 87% reporting a reduction in fatigue from standing.

Transformation After Insole Implementation and Future Prospects

Post-implementation, positive changes were evident—not just in foot stability and reduced fatigue, but also in workplace morale. Conversations among team members about their experiences became more frequent, fostering better communication and camaraderie. Encouraged by the results, management is considering further rollout of the insoles across all locations as part of comprehensive safety measures—particularly in light of Japan's rising concerns about workplace injuries due to falls, which disproportionately affect older workers.

Bridging the Gap: MEDIAID’s Worker’s Care Program

Backed by decades of experience in medical support, MEDIAID launched its Worker’s Care program in 2021, focusing on workplace safety and health. This initiative aims to improve worker satisfaction and health management, solidifying their commitment to enhancing safety in various sectors.

These efforts exemplify how attention to employee well-being can transform workplace culture, directly linking safety innovations to enhanced productivity and morale. The close analysis of workers' needs can lead to a future where safety footwear is no longer viewed as a burden but rather as an integral part of a thriving work environment.
