TRADMAN'S BONSAI × WACOAL MEN Launch Collaborative Underwear Inspired by Bonsai

Matsubaya Co., Ltd. (Headquarters: Tokyo, Representative Director: Teppei Kojima), operator of the bonsai brand 'TRADMAN'S BONSAI,' announces a collaboration with 'WACOAL MEN,' the men's underwear brand by Wacoal Corporation (Headquarters: Kyoto, Representative Director and President: Keisuke Kawanishi), launching original underwear inspired by bonsai starting Thursday, July 30, 2026.

TRADMAN'S BONSAI has consistently redefined bonsai, a traditional Japanese culture, by fusing it with street culture, fashion, and art, delivering new values to the world.

This collaboration, themed 'Japanese beauty in everyday life,' proposes a more natural way to experience Japanese culture through underwear—one of the most intimate daily products.

Bonsai is not just for display.

TRADMAN'S BONSAI does not aim to make bonsai a culture exclusive to a niche group of enthusiasts.

Whether displayed in a room, worn on the body, or integrated into lifestyle, each interaction becomes a new touchpoint with Japanese culture.

WACOAL MEN, the collaboration partner, has long pursued the value of underwear that supports daily comfort.

Bonsai, which nurtures natural beauty over time, and underwear, which supports and shapes the body every day—though seemingly different, they share a common philosophy: enriching daily life. This shared vision has made the collaboration possible.

The Japanese Beauty Created by 'BONSAI CAMO'

The design features an original graphic called 'BONSAI CAMO,' created based on an aerial photograph of TRADMAN'S BONSAI's gallery.

The lush green leaves, branching patterns, and powerful bark textures are reimagined as a camouflage pattern.

The minimalist design, evoking the 'ma' (negative space) and 'stillness' inherent in Japanese culture, seamlessly blends into streetwear styles.

Not just viewing bonsai—but wearing it.

This collaboration proposes a new way to enjoy Japanese culture.

WACOAL MEN's Functionality Meets TRADMAN'S BONSAI's Aesthetic

The base model uses WACOAL MEN's signature 'Kimochi ii Pants' (Comfortable Pants).

With full-direction stretch fabric for excellent fit and a skin-side Posi-Fit structure for stability, it excels in functionality.

By merging TRADMAN'S BONSAI's artistic vision with WACOAL MEN's expertise in underwear, a product has been born that embodies both Japanese aesthetics and comfort.
