Dear Valued Customers,

We would like to take this opportunity to express our appreciation for your continued support and the confidence that you have placed in Yamato. It has been a pleasure to manufacture our products for our valued customers, and we continue looking forward to doing business with you in the future.

As you are aware, due to the rapid escalation of tensions in the Middle East, prices for raw materials—including crude oil and naphtha—have remained high, and the procurement environment for resin materials, adhesives, packaging materials, and other items has rapidly deteriorated. In addition, various costs, such as logistics expenses, continue to rise, making it extremely difficult to maintain current prices through our own efforts alone.

We now would like to request you to note the Price Revision of some products effective October 1, 2026. Please see the attached list for details.
Yours Sincerely,
Yamato Co., Ltd.

◆Effective Date of Price Revision
Effective for shipments on or after Thursday, October 1, 2026

◆Revised Prices
Please refer to the list for details on specific items and the revisions.
