Y's to Launch Footwear Collaboration with Flower MOUNTAIN on April 15 (Wed); Pre-sale at Isetan Shinjuku Starts April 8 (Wed), Online Boutique Reservations Open Same Day.

Y's will release the second Flower MOUNTAIN collaboration on Wednesday, April 15, 2026.

This collaborative silhouette is designed based on Flower MOUNTAIN's "PUMA PUNKU" footwear, which features nature-inspired forms and artisanal craftsmanship. It is released as the second iteration, building upon last year's model with updated colors. It will be available in two colors: blue and black.

Compared to last year's model, the adjustable heel area has been expanded for a more stable fit. The comfortable fit is achieved through an insole with excellent cushioning and elasticity, and a lightweight sole with high grip.

Flower MOUNTAIN's characteristic multi-color expression is interpreted in a "monochromatic" approach, creating depth through differences in texture and hue derived from the combination of multiple materials. It is constructed from shrink leather, hair-on, and nylon.

Punching holes originally present throughout the upper have been omitted, and materials and specifications for the shoelace tips and heel elastic have been changed, incorporating refined details for a sophisticated look. The center of the vamp features a "Y's" and "Flower MOUNTAIN" double name tag, and a woven "Y's" logo label is placed on the side.

Flower MOUNTAIN's delicate handcrafted finish accentuates its unique appearance and texture.

The Y's × Flower MOUNTAIN collection will be pre-released nationwide at a pop-up store at Isetan Shinjuku starting Wednesday, April 8, 2026. Reservations will be accepted on the official online store from Wednesday, April 8th to Sunday, April 12th. It is scheduled to be available in official online boutiques and all Y's stores in Japan from Wednesday, April 15th.
