Japan market infrastructure map

Overview

Japan’s securities market is a layered infrastructure system: public regulator, self-regulatory bodies, exchange venues, PTS venues, clearing, settlement, securities finance, brokers, custodians, and disclosure rails. A broker page is only one slice of the system.

Use this page as the route map for Tokyo Stock Exchange, Osaka Exchange, Tokyo Commodity Exchange, JSCC, JASDEC, Japannext, ODX, Japan Securities Finance, Euroclear Bank Japan, Clearstream Banking Japan, JSDA, and broker / underwriting pages.

This is the infrastructure route inside securities domain; use FIEA operator registry index and JapanFG legal / financial licenses when the question turns from market plumbing to firm registration or legal status.

Cash Equity Flow

Investor
  -> broker / online broker
  -> order routing / SOR
  -> TSE or PTS venue
  -> JSCC clearing
  -> JASDEC securities settlement
  -> Bank of Japan / settlement bank cash leg

JPX’s clearing / settlement materials describe the functional split between trading, clearing, and settlement for exchange transactions. JASDEC materials explain book-entry and DVP settlement infrastructure. For FinWiki, this means a question about “stock trading” may need at least four pages: the broker, the venue, the clearing layer, and the settlement layer.

Boundary Notes

Exchange vs clearing: TSE / OSE / TOCOM are venues; JSCC is the clearing layer.
Clearing vs settlement: clearing nets and guarantees obligations; settlement transfers securities and cash.
Broker vs venue: a retail app is not the market; it is customer access to venues and infrastructure.
PTS vs dark / OTC: PTS is a regulated alternative venue route; do not treat all off-exchange execution as the same.
Securities finance vs brokerage: margin trading can involve brokers and JSF; analyze funding and collateral separately.
Domestic CSD vs ICSD: JASDEC is the domestic CSD route; Euroclear and Clearstream are ICSD / global custody interfaces.
Public company vs infrastructure page: JPX is a listed holding company; the securities domain pages explain functional infrastructure.
