Brokerage firms in Japan provide access to the Tokyo Stock Exchange (TSE) and other venues under the Japan Exchange Group (JPX), offering equities, ETFs, REITs, bonds, futures, and IPOs. Regulated by the Financial Services Agency (FSA), these firms operate in a market with ~3,900 listed companies (Nikkei 225 at ~38,500 points as of October 31, 2025, up ~15.2% YTD), a market capitalization of ~¥950 trillion (US$6.3 trillion), and strong retail participation (over 70 million securities accounts, ~30M active via NISA tax wrappers). In 2025, the sector includes ~300 FSA-registered brokers, blending megabanks (SBI, Rakuten), traditional securities houses (Nomura, Daiwa), and fintechs (Monex, Kabu.com). "Best" brokers prioritize ¥0–¥500 commissions, NISA eligibility, TSE Arrowhead platform, and FSA compliance amid a bullish market (Nikkei up 14.8% annually, driven by governance reforms).
