(Note 1) This refers to the Agreement on Ensuring the Safety of the Hamaoka Nuclear Power Station concluded between Shizuoka Prefecture, Omaezaki City, Makinohara City, Kakegawa City, and Kikugawa City and our company, as well as the Agreement on Ensuring the Safety of Municipalities Surrounding the Hamaoka Nuclear Power Station concluded between Shizuoka Prefecture, Shimada City, Iwata City, Yaizu City, Fujieda City, Fukuroi City, Yoshida Town, and Mori Town and our company.

Through mutual cooperation based on this agreement, the 3rd Regional CG HQ will transport personnel and equipment from Chubu Electric Power and Power Grid necessary for restoring power to isolated areas where roads have been cut off and power outages have occurred due to various disasters such as typhoons, earthquakes, and tsunamis, using patrol vessels belonging to the 3rd Regional CG HQ. Chubu Electric Power and Power Grid will supply power to facilities, activity bases, etc., necessary for the 3rd Regional CG HQ’s disaster response measures.

The three parties will contribute to the local community by promptly carrying out such activities and connecting them to the relief and recovery efforts in the affected areas.

The three parties will conduct a demonstration experiment utilizing an app that promotes communication between local governments and town residents ("this app") linked to e-Frail Navi, a DX tool that supports the regional comprehensive care system provided by Chubu Electric Power to local governments.

Residents participating in this demonstration experiment will be able to receive notifications of local events that were previously confirmed in publicity magazines and posters, as well as information tailored to individual circumstances that was previously received by mail from Toin Town, via this app developed by Chubu Electric Power.
Furthermore, residents can use this app to accumulate points through checking in at local government events and engaging in daily healthy activities with the Toin Town Health Promotion Point Card, as well as to provide feedback to Toin Town on the results of their actions in response to the information provided.

This will enable Toin Town to go beyond simply disseminating information and create a system for receiving information from residents, with the aim of working with residents to develop a data-driven health management system and services tailored to individual health conditions.

Toin Town aims to extend healthy life expectancy by fostering health awareness among its residents and maintaining and improving their life functions, under the future vision of "Healthy and Active Town". Through this demonstration experiment, we aim to create a town where residents can live with peace of mind, so that each individual can receive appropriate support and continue to live independently according to their abilities in their familiar neighborhoods for as long as possible.

Chubu Electric Power and nekoriko will verify the effectiveness of this app and confirm operational issues, while also considering its future introduction and expansion to other municipalities. By working to solve various social issues in an aging society, we will contribute to the realization of a safe and secure community.

Initially, our company planned to establish TCK in collaboration with Helsinki Education Pty Ltd (Headquarters: Victoria, Australia; Director: KAM MING YU; “Helsinki”), which operates HEI's early childhood education program in Australia, and Alpha Corporation, which operates childcare services in Japan(Press release issued on February 4, 2025).

As a result of subsequent discussions, the framework will change so that our company and Alpha Corporation will establish TCK. HEI, a Finnish educational research institution that distributes licenses and curriculums for HEI Schools (Note) worldwide, will be directly involved in dispatching Finnish teachers. This will provide a higher quality of service than originally planned, as teachers with experience in HEI's educational philosophy and curriculum at the kindergartens in Finland will be involved in the operation.

HEI Schools Nagoya Sakae, an international preschool located in The Landmark Nagoya Sakae, currently under development in Naka-ku, Nagoya City will open as scheduled in April 2026.

We will continue to provide services that enrich our customers' lives, including childcare support services, and contribute to solving local issues and revitalizing the community.

(Note) It is a Finnish-style early childhood education program developed by HEI based on research at the University of Helsinki, and is currently being implemented in more than 14 countries around the world (as of July 31, 2025).

1 Current status of the domestic lumber market

The domestic market for structural timber for residential use is dominated by foreign products in terms of price and strength. Because of this, even when the time comes to harvest Japan's abundant forest resources, most of them are not being put to effective use, limiting their contribution to the recycling of forest resources and the realization of a decarbonized society.
In addition, many domestic laminated wood manufacturers rely on imports from Europe for their raw material, "laminar (sawn lumber)", and due to exchange rate fluctuations and the current uncertain global economic situation, it is difficult to predict stable procurement.

2 Overview of Business Scheme

Kushiro Wood Products will establish Japan's largest sawmill in Hokkaido, equipped with European-made lumbering machinery and kiln dryer. It will manufacture laminar from Hokkaido-grown logs such as Todo-fir, which are of the same quality as imported wood, and sell it to domestic laminated wood manufacturers. In addition to laminar, the company plans to sell dimensional lumber (2 x 4 lumber) and other products manufactured at this mill to housing manufacturers and other customers.
At the time of the announcement in July 2024, the initial plan was to establish a new laminated wood factory equipped with a laminated wood production line to mainly manufacture and sell laminar for residential structures, in addition to the above-mentioned sawmill. However, after verifying the profitability of the business, it was decided not to establish the laminated wood factory and instead to specialize in the manufacture and sale of laminar and dimension lumber.

In order to secure distribution volume and reduce costs, the mill will introduce large European-made machinery to enable mass production and stable supply. This will enhance its competitive advantage over imported woods in terms of quality, price, and distribution volume, leading to the promotion of domestic materials by housing manufacturers.

We will engage in lumber business in Kushiro, Hokkaido, with the goal of expanding the domestic lumber market, thereby contributing to the realization of a decarbonized society, the preservation of forest cycles, and the revitalization of the local economy.
