What you will and will not find here
Why are there four guides instead of many short articles?
Earlier in 2026 the English article set was consolidated into these guides. Short standalone explainers were merged so that each topic is covered in one place, end to end, rather than split across pages that each answered part of a question. Older article URLs redirect to the guide that now covers the subject.
Is the English edition a translation of the Japanese site?
No. The guides are written directly in English for an international audience. The Japanese edition is much larger — over 330 articles — and goes considerably deeper, particularly on Japanese regulation such as the SSBJ standards, the Act on Promotion of Global Warming Countermeasures and the GX-ETS.
Can I rely on these pages for a compliance decision?
Treat them as orientation, not as advice. Requirements in this field — especially the EU regime — are actively changing, and the guides state the direction rather than every current deadline. Always check the primary source before acting.
