What Yoshimei just published
Yoshimei released its first-ever EPD in July 2025 for glued laminated timber made from Japanese cypress (Hinoki), JAS‑certified and intended for structural beams and columns in residential building. The declaration is listed under the EPD Hub Core PCR v1.1 and verified by the program operator EPD Hub. Scope language indicates structural use across common sizes, which reads as a practical fit for framing and timber contractors.
Why it matters for specs
On projects that request product-specific EPDs, a supplier without one forces design teams to assume a penalty in their carbon accounting. Having a verified declaration removes that friction, keeps Yoshimei in the running, and shortens back‑and‑forth during submittals. This matters alot for timber bids.
Product category, at a glance
The debut covers glued laminated timber, the workhorse structural element beside CLT and LVL in mass timber packages. The description signals everyday applicability, not a boutique one‑off, which is exactly what specifiers hope to see when schedules are tight and substitutions are risky.

Competitor check, as of January 2026
Two peers already publish current EPDs covering glulam or adjacent engineered wood. Kalesnikoff lists current EPDs for glulam and CLT. Stora Enso maintains a broad set across CLT, GLT, and LVL in Europe. On the other side, Structurlam shows no current EPDs in public listings right now. Net effect, Yoshimei has entered the transparency arena, catching up to established publishers and gaining visible advantage where some rivals still lag.
Program operator choice
The EPD sits with EPD Hub, a recognized operator that serves construction products across geographies. Operator choice affects format and where AEC teams expect to find documents, not the underlying life‑cycle math. For manufacturers building a portfolio, consistency of operator and PCRs makes portfolio maintenance faster over time.
Developer credits
No external LCA consultant is named on the public record for this listing. If a partner supported the work, adding that credit in a release note helps procurement teams route questions quickly.
Website visibility check
We did not find a dedicated EPD or sustainability page hosting the document on yoshimei.com during our review on January 21, 2026. Adding a simple “Environmental Declarations” page, with the PDF and a short summary per product, will increase discovery in pre‑bid searches and reduce email churn.
What this signals next
A first EPD is often the opening track, not the whole album. Teams that extend coverage to closely related products, for example additional glulam dimensions or companion elements in the same supply chain, see smoother spec inclusion across entire timber packages. Choose an LCA partner that quarterbacks data collection inside the plant and across suppliers so engineers and production can stay focused while the paperwork moves forward.
