We are seeking "initiatives" to create the future together! Introducing the "Tanseisha Sustainable Co-creation Partner Awards 2026"


Tanseisha will begin accepting applications for the "Tanseisha Sustainable Co-creation Partner Award 2026" (hereinafter, "this award") from Tuesday, July 21, 2026, targeting partner companies (cooperating companies, design partners, etc.) that support Tanseisha's supply chain.

This award program was established last year following the formulation of sustainable guidelines for procurement and design, and seeks to recruit and recognize the "sustainability promotion initiatives" of partner companies that support Tanseisha's supply chain. By "sharing and giving back" the best practices submitted, we aim to foster awareness and practice throughout the entire supply chain, and to realize a sustainable society and enhance value.

Our company is still in the early stages of development in promoting sustainability. We would like to work together with you, drawing on your on-the-ground wisdom and daily ingenuity. We look forward to receiving many applications.
