TOSO COMPANY,LIMITED Company Overview

Due to the recent escalation of tensions in the Middle East, there has been a rise in raw material prices and energy costs due to soaring crude oil prices, along with disruptions in the supply chain of crude oil and petroleum products. Consequently, there are some challenges emerging in the procurement of raw materials that our company sources, leading to an uncertain outlook regarding future procurement volumes and price trends. Our company will make every effort to maintain stable supply through measures such as securing inventory and reviewing production plans. However, depending on future circumstances, we may be forced to impose shipping restrictions, delays in delivery, or price revisions for our products. We will continue to monitor the situation closely and do our utmost to ensure stable supply, but if it becomes necessary to implement the aforementioned measures, we will inform you as early as possible. We kindly ask our customers for their understanding and cooperation regarding these circumstances.

Toso Co., Ltd. (Headquarters: Chuo-ku, Tokyo / President: Masato Yaeshima), a comprehensive interior manufacturer by the window, has started a donation initiative for plastic bottle caps and used stamps as part of its sustainability efforts from the fiscal year 2025 (ending March 2026). The proceeds from the sale of the collected caps and stamps will be used to purchase vaccines for children in developing countries through the certified NPO "Japan Committee for Vaccines for the World's Children" (hereinafter referred to as JCV). This initiative not only supports children in developing countries but also contributes to reducing greenhouse gas emissions by recycling plastic bottle caps that would otherwise be incinerated. Additionally, since it is an initiative that employees can easily participate in, it is expected to enhance awareness of sustainability within the company. This year, activities have started mainly at business locations in the Tokyo and Ibaraki areas, such as the headquarters and the Tsukuba plant. Our group will continue to advance its sustainability efforts toward the realization of a sustainable society. Please check the attached materials for the cumulative donation results for the fiscal year 2025.
