TL;DR

Japan’s capital markets ecosystem comprises five interconnected layers: issuance (primary), trading (secondary), clearing, settlement / depository, and regulation / self-regulation. The system spans equity, bond (JGB and corporate), derivative (listed and OTC), securitized-products, and security-token markets, supported by a network of exchanges, clearing corporations, depositories, regulators, and self-regulatory organizations.

This entry is the cross-cutting ecosystem anchor that ties the securities domain together and bridges to finance (corporate-finance side), derivatives (instrument layer), money market (short-end), structured finance (securitization), and real-estate finance (J-REIT) domains.

Wiki route

This entry sits under securities index as the ecosystem anchor. Pair it with japan-market-infrastructure-map for the venue / clearing / settlement plumbing detail and japan-listed-financial-groups-investable-universe for the listed FG investable universe. The household-investment side is in nisa-2024-flow. The corporate-finance side is in finance index.

1. Issuance (Primary Market)

The primary market is where issuers raise new capital from investors.

4. Settlement and Depository

Settlement transfers ownership of cleared trades; depositories hold the underlying records.
