Morus will host pop-up stores at Gold’s Gym, one of Japan’s largest fitness gym chains, to sell its KAIKO brand products for approximately two and a half months starting July 13, 2026. Pop-up stores will be in three major Tokyo locations (Harajuku, Ginza, and Higashi-Nakano).
This collaboration with Gold’s Gym aims to establish a strong connection with health-conscious fitness enthusiasts who never compromise on nutrition for body conditioning. By showcasing our products at Japan’s premier hubs for dedicated gym-goers, we aim to enhance our brand’s credibility.
Furthermore, we will offer a pre-release trial version of our new supplement, scheduled for a nationwide launch this autumn, as the “SilkDiet+ Trial Set.” This initiative will not only raise awareness for the new product but also deliver a cutting-edge nutritional experience to our core users ahead of schedule.
During the event period, in addition to in-store sales, we plan to host regular tasting events. Visitors will have the opportunity to experience the taste and quality firsthand while learning more about the unique appeal of our products from our expert staff.
All products will be available at special Gold’s Gym promotional prices.
