Methodology (this batch)
BrokerMafia's September 2026 shortlists are editorial discovery tables ordered by public-fact criteria: regulatory tier (published register IDs), entity transparency, longevity or citable public scale, and product/authority clarity. BrokerMafia keyword-page presence is a tie-break only. We refuse paid rank, star scores, and copied review prose. Order can change when registers or public disclosures change — this batch is dated September 2026.
Scope: Domestic Type I financial instruments business operators on the FFAJ OTC FX registered-firms list (2026-09-25) with citeable 関東/近畿財務局長（金商） numbers. Order weights public scale and disclosure clarity — not spreads. Framework: /best-forex-brokers-japan/.
- Regulatory tier — published tier-1 register IDs where we can cite them.
- Entity transparency — can a reader match agreement → register row?
- Longevity / public scale — years, listing, or citable industry revenue lists.
- Product / authority clarity — FX entity vs exchange vs FMCSA broker vs DOI producer.
- BrokerMafia research presence — tie-break only.
Marketing claims (spreads, bonuses, pass rates, “best broker awards”) are labeled and never used as primary rank keys.
