Y’s will release the second installment of its collaboration with Flower MOUNTAIN on Wednesday, April 15, 2026.
This collaboration silhouette is based on Flower MOUNTAIN's 'PUMA PUNKU' footwear, which is attractive for its nature-inspired forms and manual processes. Following the same model announced last year, this second release features updated colors, available in blue and black.
Compared to last year's model, the size adjustment range at the heel has been expanded to achieve a more stable fit. The insole, with its excellent cushioning and elasticity, combined with a lightweight, high-grip sole, provides exceptional comfort.
Interpreting Flower MOUNTAIN's characteristic use of multiple colors in a 'monochromatic' way, the design expresses depth through the textural and tonal differences created by combining multiple materials. It is constructed from shrink leather, hair-on, and nylon.
The design incorporates refined details, such as removing the original punching holes across the upper and changing the materials and specifications of the lace tips and heel elastic. The center of the instep features the double branding of 'Y’s' and 'Flower MOUNTAIN', while the side displays the 'Y’s' logo on a woven label.
Flower MOUNTAIN's delicate handcrafted finish accentuates the unique expression and texture.
Y’s × Flower MOUNTAIN will be pre-launched nationwide at the Isetan Shinjuku pop-up store starting Wednesday, April 8, 2026. Pre-orders will be accepted on the official online store from Wednesday, April 8 to Sunday, April 12. The collection is scheduled to be available at the official online boutique and all Y’s stores in Japan from Wednesday, April 15.
