2. Business model

Online brokerage economics

  • Matsui says it concentrates management resources on online-based businesses; in FY2024, Japanese equities for retail investors accounted for approximately 80% of total net operating revenue.^[source:matsui-ir-2025]
  • The same report frames Japanese equities as the key business while calling for revenue diversification through online products including FX, U.S. equities and investment trusts.^[source:matsui-ir-2025]
  • FX is now material rather than purely optional: it accounted for 10% of FY2024 net operating revenue and had grown to 3.8bn yen from around 1.0bn yen in FY2021.^[source:matsui-ir-2025]
  • U.S. equities began in 2022; Matsui later added margin transactions, new NISA support and a roughly 4,900-security lineup as of September 2025.^[source:matsui-ir-2025]

Self-directed retail strategy

Matsui is not a universal financial group. Its strategic position is a self-directed retail brokerage platform. Integrated Report 2025 calls Matsui the only independent firm among the five major online securities brokers, while the four peers are subsidiaries of conglomerates with much larger customer bases. That is why the page should remain separate from bank, telecom and commerce-group pages even when peer links overlap.^[source:matsui-ir-2025]

Historical inflection

The historical break is May 1998: Matsui’s public annual securities report says the company started “Netstock”, the first full-fledged online brokerage service in Japan, and the first online margin trading service in Japan. This page treats 1998 as the shift from face-to-face retail brokerage to online self-directed brokerage.^[source:matsui-asr-2024]

4. Competitive position

  • Against SBI / Rakuten / Monex / MUFG eSmart: Matsui explicitly positions itself as independent in the major online-broker peer group; peers have broader group ecosystems.^[source:matsui-ir-2025]
  • Against face-to-face brokers: Matsui’s advantage is low-cost online execution and self-directed retail UX, not branch-based advisory coverage.
  • Policy sensitivity: zero-commission equity trading, NISA asset-building flows, cybersecurity and system stability directly affect online-platform economics.
