Japan capital markets ecosystem overview

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.
