Titanist Laboratories Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Hiroki Kurita; hereinafter "the Company") is pleased to announce the signing of a sponsorship agreement with professional ultrarunner Tomomi Otoh, with the sponsorship officially commencing on June 1, 2026.

Through this agreement, we will support Ms. Otoh’s competitive activities and leverage the unique insights and firsthand experiences of a top-tier athlete to advance product development and public communications. Our goal is to enhance awareness of our technologies and products and to create new value through this collaboration.

Background of the Sponsorship Agreement

This sponsorship was made possible because Ms. Otoh had previously been using our products. Through her actual experience with our products, she came to resonate with our technological approach and philosophy toward product creation, leading to this partnership in the form of sponsorship.

Going forward, the Company will continue to support Ms. Otoh’s athletic pursuits while actively incorporating the authentic perspectives and insights of a top athlete into our product development and information dissemination. By reflecting the voices of athletes who continuously challenge themselves in extreme environments, we aim to develop products and technologies that are more practical and closely aligned with people’s daily lives and physical well-being.

Additionally, through this sponsorship, we aim to increase brand recognition within the athletic community, widely communicate the value of our product development philosophy—'Nature and Science'—and drive the creation of new value.
