The first collaborator for this commemorative event is professional runner Daichi Kamino.

Mr. Kamino is the director of RETO Through the brand Leto, they are involved in a variety of running-related activities, including manufacturing and a running club.

RETO, which means challenge in Spanish, is a brand that continues to create new ideas from the perspective of athletes.

We resonated with founder Daichi Kamino's philosophy of "wanting to use good things for a long time," and this commemorative first collaboration became a reality.

The motif is the Hakone Ekiden, which was a turning point for Kamino himself, and the collection is inspired by the sashes that connect the team, and is inspired by bonds.

Connecting, unity, believing, a chain of feelings...

This bracelet captures this importance with a simple, sophisticated design using a "knot" motif.

The matching ring also has a double-strand style design, and is characterized by its sophisticated design that makes a strong impression.
