[First in Japan] Higashi-Mikawa Companies and Startups Collaborate on a Demonstration Project to Create Sustainable Workplaces Through Bereavement Support
Waterhuman Inc. is partnering with a consortium of seven companies in Japan's Higashi-Mikawa region for a demonstration project focused on "Bereavement and Productivity." Spearheaded by the Sala Group's emCAMPUS STUDIO, this first-of-its-kind initiative aims to support 'working chief mourners' by providing practical and emotional care, while gathering data on the economic and personal impact of grief in the workplace. This unique "Higashi-Mikawa Model" leverages a private-sector-led ecosystem to help SMEs access and test innovative services, with the goal of establishing a new, more compassionate standard for employee support across Japan.

Waterhuman Inc. (Headquarters: Bunkyo-ku, Tokyo; CEO: Kakuaki Shintani; hereinafter "Waterhuman") announces the start of a demonstration experiment on "Bereavement and Productivity." This will be conducted with a consortium of companies from the Higashi-Mikawa region (eastern Aichi Prefecture), centered around the co-creation hub "emCAMPUS STUDIO," which is operated by the Sala Group. The Sala Group, with SALA CORPORATION (Headquarters: Toyohashi City, Aichi Prefecture; President & CEO: Goro Jinno) as its holding company, consists of 48 life-related businesses.
Traditionally, local ties and rituals supported bereaved families in Japanese society. However, with the recent "weakening of community ties" and the "rise of nuclear families," this burden is ever-increasing. Furthermore, the "aging of the labor force" due to labor shortages and the advent of a "mass death society," where many are expected to face the death of relatives within the next five years, are serious issues. Against this backdrop, there is a sharp increase in "working chief mourners" who must handle complex procedures and grieve while continuing to work. This is a pressing issue that society as a whole must address. In these modern times, providing "mental care" and "reducing the practical burden" for employees who become "working chief mourners" has become a critical management issue that affects a company's sustainability.
✦ "Co-creation" that Happened in Higashi-Mikawa
This demonstration experiment originated at emCAMPUS STUDIO, a co-creation hub in Higashi-Mikawa operated by the Sala Group.
For Waterhuman, which found it difficult to develop a demonstration field on its own, emCAMPUS STUDIO, which provides support services for challengers aspiring to start businesses in Higashi-Mikawa, acted as a bridge. In the Higashi-Mikawa region, an area with a concentration of manufacturing and logistics industries supported by the local economy and many sincere managers, seven local companies that resonated with Waterhuman's vision responded, leading to this collaboration. This initiative demonstrates that "Higashi-Mikawa has the foundation to connect a startup's challenge to social implementation."
Starting from emCAMPUS STUDIO, we will create new value by supporting working people in Higashi-Mikawa who are dealing with "grief," and update this region to become "the most supportive region in Japan for 'challengers' and the kindest to 'working people'."
Novelty of Co-creation through the "Higashi-Mikawa Model"
The scheme, "a co-creation hub operated by a regional core company acts as a hub, connecting small and medium-sized enterprises (SMEs) from different industries to simultaneously verify one startup's service," is unprecedented in its novelty.
-
Eliminating "Search Costs" and "Verification Risks" for SMEs
SMEs lack the resources to independently search for new startup services and verify their effectiveness. Therefore, by having a core company act as a "connoisseur" and having multiple SMEs conduct demonstrations simultaneously, the entire region can benefit from cutting-edge services while minimizing the cost and risk per company.
-
Ensuring Statistical Significance
While a single SME might only have a few cases of "bereavement" per year, a consortium of companies can gather diverse data in a short period, enabling meaningful analysis. The same applies to demonstration experiments for other services. -
A "Private Sector-Led" Ecosystem
While many regional projects are led by the government, this project is an autonomous consortium based on the trust and local ties among private local companies. This allows for flexible verification that is grounded in on-site realities.

✦ Challenges Addressed by Waterhuman
-
The Arrival of a Mass Death Society: All Employees Will Become Bereaved by 2030
Japanese society is currently in a transition to an unprecedented "mass death society." According to research by Professor Carl Becker (Professor Emeritus and Researcher at Kyoto University), an advisor to this demonstration experiment, it is predicted that most of the working population will face the death of a close person within the next five years. With an eye on the inevitable future where "all workers will be bereaved by 2030," we aim to quickly establish preparedness in local communities and companies.
-
Economic Loss of "Approx. 3 Trillion Yen": Bereavement Grief as a Management Issue
Professor Becker also states that grief from bereavement is likely to lead to decreased productivity and psychosomatic disorders. If proper care is not received, about 20% of the bereaved may suffer from serious mental health problems. Furthermore, it is estimated that the economic loss due to bereavement grief reaches about 3 trillion yen for Japan as a whole. As labor shortages become more severe, issues associated with bereavement are no longer a personal problem but a "management issue" that affects corporate sustainability.
-
A New Safety Net to Prevent "Working Chief Mourners" from Becoming Isolated
In modern times, where mutual support through local and blood ties has weakened, there is an increasing number of cases where individuals become isolated as they bear the burden of complicated post-mortem procedures and psychological stress alone. The typical "few days of bereavement leave" granted by companies does not cover the months-long burden of administrative procedures and emotional recovery. Waterhuman aims to establish a new safety net that protects Japan's productivity and the dignity of its workers by building a system based on scientific evidence to bridge this gap.
[In a preliminary survey (*), about 70% of those with experience as a chief mourner responded that they "desire support from their employer."]




✦ Overview of this Demonstration Experiment
Japan's First Empirical Approach to "Bereavement and Productivity"
This demonstration experiment aims to clarify the relationship between the "actual situation of employees during bereavement leave" and their "post-return productivity" based on empirical data—an area that has not been sufficiently accumulated as data or considered for improvement in Japanese companies.
-
Period: March 1, 2026 - August 31, 2026
-
Target: 7 companies in the Higashi-Mikawa region
-
Provided Content: For employees on bereavement leave, provision of a "post-mortem procedure list" created based on individual interviews and circumstances, as well as a private consultation service via chat.
-
Verification Content: In this experiment, we will acquire and analyze "data related to bereavement" from the following three perspectives:
-
Visualization of bereavement costs (quantitative data)
-
Impact of bereavement grief on individual productivity (qualitative data)
-
Estimation of long-term effects on turnover rates and engagement scores
-
-
Verification Method:
-
Company-side records (on an occurrence basis):
-
Recording "number of bereavement cases," "days of bereavement leave taken," "number of additional paid/half-day leaves taken," etc., on a management sheet.
-
-
Questionnaire surveys:
-
For managers: Burden on the workplace due to absence, post-return performance (subjective evaluation), etc.
-
For users: Time required for procedures, psychological burden, satisfaction with support, etc.

✦ Comments from Participating Companies


Sala Group
SALA CORPORATION (Headquarters: Toyohashi City, Aichi Prefecture; President & CEO: Goro Jinno) is the holding company for a corporate group of 48 companies that develop various businesses supporting life and business. With eastern Aichi and western Shizuoka prefectures as our core area, we handle comprehensive life-related businesses, including energy supply centered on gas and electricity, housing, infrastructure development, and imported car sales, as well as urban infrastructure development. Under the basic philosophy of "making living spaces more beautiful and comfortable," we contribute to the realization of a prosperous society by providing products and services tailored to customer needs.
【emCAMPUS STUDIO】
emCAMPUS STUDIO is a hub for creating a rich future for Higashi-Mikawa through 'co-creation.' The fact that local companies responded to the significant social challenge of 'supporting working chief mourners' and came together as one team is the very form of co-creation that this facility aims for.
As a hub connecting the passion of startups with the aspirations of regional companies, we will strongly support this project so that this 'Higashi-Mikawa Model' can grow into a new social infrastructure that supports working people.

Sala Butsuryu Co., Ltd.
The main players in logistics are 'people.' An environment where our drivers and on-site staff can work with peace of mind leads to the highest quality logistics. We will take on this challenge as a pioneer within the group.

Shinnichi Kogyo Co., Ltd.
SMEs, which account for 99.7% (approx. 3.3 million companies) of Japanese enterprises, are in the midst of a transformation for survival. The strategic options to break through this difficult situation are either to expand in scale through M&A, or to share resources and knowledge through strong collaboration between companies. We have believed that the latter, 'collaboration,' is an extremely effective survival strategy for regional companies. This project is an attempt to embody this very strategy in the land of Higashi-Mikawa.
The attempt for a metropolitan startup, a regional core company, and SMEs like us to work on a joint demonstration as 'equal partners' is an extremely rare case. For a company of our size, with about 50 people, there are limits to discovering advanced services and verifying their implementation effects. However, we are convinced that by taking on the challenge as 'one entity' of regional companies, we can create new value that could never be reached alone.
Our company has walked the path as an 'unsung hero' supporting industry from the manufacturing floor. However, what is being questioned in the coming era is the attitude to move beyond existing frameworks on one's own. As a 'first penguin,' we will fearlessly dive into unknown territory first, demonstrating our identity and resolve.
This initiative is also a challenge to build a unique, region-originated ecosystem that provides an attractive demonstration field for startups. We will join hands with new partners to co-create and orchestrate a future full of hope.

Subaru Higashi-Aichi Hanbai Co., Ltd.
As an authorized SUBARU dealer, we deliver 'peace of mind' and 'enjoyment' to our customers daily. That value is supported by the efforts of many staff, including sales, maintenance, and reception. The physical and mental state of each employee directly connects to the overall strength of the dealership.
That is why how we support our employees when they face difficulties or lose a loved one is not just a matter of welfare but a management issue itself. However, there are limits to what we can systematize on our own for this theme.
Therefore, we have decided to incorporate external expertise and collaborate with regional companies this time. Through this initiative, we will elevate our company's philosophy of 'maximizing the happiness of our employees and their families' into a concrete and sustainable system. Starting from this alliance, we will build a new corporate model where regional companies collaborate to address social issues.

Toyohashi Mokko Co., Ltd.
We currently have about 40 employees, and bereavement is not a frequent occurrence at this time. However, we believe it is important to have a system where we can introduce experts as an appropriate consultation point when an employee loses a close relative. We participated in this initiative as one way a company can 'be there' for its employees.
We also feel that supporting employees in their time of grief ultimately leads to protecting the quality of our craftsmanship.

Chubu Gosei Jushi Kogyo Co., Ltd.
At our company, 45% of employees are in their 50s or older, and 25% are in their 40s, meaning about 70% of our staff will face 'parental end-of-life care' in the near future. However, current support is limited to leave and funeral offerings. We want to establish a support system that goes one step further for the mental aspects and complex procedures that employees tend to handle on their own. We believe expanding our welfare benefits not only increases employee peace of mind but also demonstrates our stance as a 'company that values its employees' externally, and we expect it to strengthen our recruitment branding.

Marushime Co., Ltd.
Our company upholds a 'Human Resources First' policy and aims to create a workplace where employees can work with a sense of purpose. Within this, we believe that building a flexible corporate support system that corresponds to employees' life stages is of great value, and we decided to participate in this initiative thinking it would be a step toward that.
It is a great honor to participate in a challenge to create new value that cannot be achieved alone, and we expect that through the collaboration of diverse local companies, this initiative will take root in the region and become a model case for sustainable regional development.

Yamasan Co., Ltd.
At our company, which currently has about 70 employees, issues related to the senior generation, such as nursing care and inheritance, are steadily becoming more apparent as the age range of our workforce expands. With no one in the company, including myself, having specialized knowledge, we believe that securing a reliable consultation destination for our employees is extremely meaningful for the organization, and we decided to participate in this project.
While cases are limited within our own company, we see the ability to verify the necessity of the service from multiple perspectives through collaboration with other companies as a very valuable opportunity. This alliance brings together companies of various industries and sizes, and we expect to gain an understanding of needs that we couldn't obtain on our own. By accumulating verifications and experiments within this framework, we hope to contribute to the further revitalization of the Higashi-Mikawa area.

Waterhuman Inc.
In Higashi-Mikawa, we found the best partners to tackle the unexplored territory of 'bereavement and productivity,' an area that has not been in the spotlight until now. The essence of this demonstration experiment is not merely to collect numerical data. It is to present concrete solutions based on scientific evidence to the question of how companies should support 'working chief mourners' during the most difficult times of their lives. We believe this area holds immeasurable potential to make Japanese organizations stronger and kinder.
Together with the companies of Higashi-Mikawa, we will create a 'new normal' from here to save working people all over Japan.

Professor Carl Becker
Recent research has revealed that the loss in labor productivity due to bereavement grief is enormous. However, in Japanese companies, it has been made invisible as a personal problem. This demonstration experiment, in which the companies of Higashi-Mikawa are addressing this issue as an organization and attempting to visualize the data, has the potential to become a world-leading case. I wholeheartedly support this courageous first step.
