Artist Yu Nagaba's designed "Us 4 IRIOMOTE" charity collaboration items arrive again this year. April 15 is Iriomote Wildcat Day

Since its founding in 2003, the outdoor footwear brand "KEEN," which defines "everywhere without a ceiling" as the outdoors and proposes innovative hybrid footwear manufactured with reduced environmental impact, will release new charity collaboration items for the "Us 4 IRIOMOTE" project. This project aims to pass on the nature and culture of Iriomote Island to the next generation. The items will be available at the KEEN official online store, KEEN direct stores (excluding some), and authorized retailers.

A portion of the sales from these charity goods will be donated to activities for the natural environmental protection of Iriomote Island, cultural inheritance, and educational activities on ethical travel.

What is Us 4 IRIOMOTE?

What we can do for the tomorrow of Iriomote Island.

"Us 4 IRIOMOTE" is an action-oriented project where each of "Us" thinks about and acts on what we can do to pass on the rich nature and culture of Iriomote Island to "tomorrow." Initiated by KEEN in 2019, the project continues to receive our support. It also advocates a new travel style called "ethical travel," where one approaches the nature and life of travel destinations with respect and compassion.

It will celebrate its 7th anniversary on April 15, 2026 (Iriomote Wildcat Day).
