WILDSIDE Yohji Yamamoto and TRADMAN’S BONSAI Unveil Bonsai-Focused SS26 Capsule

The headline here is timing and access: WILDSIDE Yohji Yamamoto’s six-piece SS26 capsule with TRADMAN’S BONSAI went live on Wildside-online at 6 Mar 12:00 JST, with each product page carrying the caption “[6 Mar 12:00 JST release]” and image file markers like SK-Y35-253 for the reversible souvenir jacket. The Yohji Yamamoto site had already listed the collaboration in its Latest Highlights on Feb 26, 2026, but Wildside’s product timestamps indicate the public retail moment landed on March 6.

Design and authorship are specific: the capsule pairs WILDSIDE YOHJI YAMAMOTO with TRADMAN’S BONSAI, led by Teppei Kojima, whom Hypebeast frames as the collection’s visionary. The botanical anchor is the Goyomatsu Moyogi‑Mei ‘501’ (Japanese Five-Needle Pine), a motif Hypebeast says is “particularly dear to Kojima.” That pine and additional specimens are literal motifs here, not vague references.

The reversible souvenir jacket is the showstopper: Hypebeast calls it a jacket with “bold monochromatic embroidery of the ‘501’ pine on the back” and an opposite face made from an “intricate jacquard-woven collage of TRADMAN’S BONSAI’s most prized specimens, including the Black Pine and Juniper, resulting in a unique camouflage-like textile.” Wildside’s image asset for this piece appears under SK-Y35-253 and was listed with the 6 Mar release caption. The effect is tactile-visual: heavy, graphic embroidery on one side and a dense jacquard collage on the other that reads like a couture camo — exactly the blend of dark Yamamoto restraint and botanical flamboyance Hypebeast describes as “hidden playfulness.”

The rest of the capsule reads as coordinated utility with botanica slipped into lining and prints. The Cotton Chino 2B Tailored Collar Jacket (SK-J40-001) and matching Cotton Chino Asymmetry Pocket Drawstring Pants (SK-P57-001) use cotton chino exteriors that keep silhouettes minimalist while hiding the bonsai collage as a lining detail — Hypebeast notes that lining adds “depth and discovery.” A Rayon Print Shirt (SK-B19-252) carries printed bonsai motifs, while a Bonsai Embroidered T-shirt (SK-T30-003) and a Bonsai Embroidered Tie (SK-N01-401) finish the six-piece set listed on Wildside’s product pages.

Material calls are explicit: cotton chino for the tailored jacket and pants, rayon for the print shirt, jacquard weaving for the collage panels, and bold monochrome embroidery for the jacket’s back. Wildside’s product imagery and filenames back those identifications, and the Yohji site’s Feb 26, 2026 highlight places the drop in the brand’s recent cadence alongside other WILDSIDE collaborations earlier that month.

This capsule isn’t a surface-level print drop; it is deliberate iconography recast as wardrobe objects — the Goyomatsu Moyogi‑Mei ‘501’ stitched, printed, and jacquard-woven across pieces that launched on Wildside at 6 Mar 12:00 JST. If you track product codes for samples or resale angles, note SK-Y35-253, SK-J40-001, SK-P57-001, SK-B19-252, SK-T30-003, and SK-N01-401 as the official image identifiers tied to the launch.
