WACOAL MEN Collaborates with TRADMAN'S BONSAI to Launch Bonsai-Themed 'Comfortable Underwear'

WACOAL MEN × TRADMAN’S BONSAI [Comfortable Underwear] Model No.: WT3991, Colors: BL, GR

Wacoal Co., Ltd. (Headquarters: Kyoto City, Kyoto Prefecture; President and CEO: Keisuke Kawanishi) announces the launch of a collaborative product between its men's underwear brand 'WACOAL MEN' and 'TRADMAN'S BONSAI,' created by Matsubaya Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President: Teppei Kojima). Inspired by the art of bonsai, the new 'Comfortable Underwear' will be released on Thursday, July 30, 2026, and will be available nationwide at authorized retailers and online via the Wacoal Web Store and other e-commerce platforms.

TRADMAN'S BONSAI has consistently redefined Japanese culture by integrating the traditional art of bonsai with street culture, fashion, and art. This collaboration was born from the shared philosophy between the concept of bonsai—cultivating natural beauty over time—and underwear, which supports bodily comfort and well-being in daily life.

The theme of this collaboration is 'Bringing Japanese Beauty into Everyday Life.' It aims to naturally incorporate traditional Japanese aesthetics and values into daily routines. After extensive planning to balance personal expression with everyday wearability, the collaboration centers on WACOAL MEN’s signature 'Comfortable Underwear.' The design features 'BONSAI CAMO,' a graphic pattern inspired by aerial photographs of bonsai gardens, reimagined as camouflage. This minimalist and refined design evokes Japanese concepts of 'ma' (negative space) and tranquility, seamlessly blending into daily life. The waistband features a simple logo design, making it suitable for streetwear styles.

Functionally, the underwear uses WACOAL MEN’s signature all-direction stretch fabric for a body-hugging fit. The front section features an inner-positioned support structure that stabilizes the genital area for enhanced comfort.

WACOAL MEN, whose brand concept is 'Let’s create underwear you can’t keep up with,' aims to propose a new aesthetic consciousness where tradition and daily life harmonize through this collaboration.

Product Features

A collaborative 'Comfortable Underwear' by WACOAL MEN and TRADMAN’S BONSAI.

The waistband features a simple logo design, compatible with streetwear styles.

Made with the special 'Flex Move®' fabric, offering superior all-direction stretch and comfort. The front panel uses an independent inner-positioned support structure to keep the genital area securely in place, reducing shifting during sitting and standing.

The inner front fabric features breathable, sweat-wicking, antibacterial, and odor-resistant properties for enhanced comfort. The leg openings use free-cutting fabric to minimize visible lines under outerwear. Comes in a bonsai-patterned original packaging.

※ 'Flex Move®' is a high-stretch, freely cut circular-knit fabric designed for exceptional comfort. It stretches easily with light force and quickly returns to its original shape, ensuring a comfortable fit.
