3. FX (店頭外国為替証拠金取引) and CFD spreads: Spread-based revenue from 三菱UFJ eスマート証券 FX (over-the-counter FX), くりっく365 exchange FX, and 取引所CFD (株365); dedicated spread disclosure page published regularly.
4. Investment trust (投資信託) and NISA platform fees: Trailing fees from investment trusts held on platform; revenue from distribution of mutual funds (eMAXIS Slim focus line-up in iDeCo), NISA accounts, and foreign-currency MMFs.

Expansion highlights7 records

Broad incumbents

• Daiwa Securities: One of Japan's 'Big Three' securities houses, offering full-service brokerage, investment banking, and asset management. Overlaps with Kabu.com Securities in retail brokerage and investment trusts but operates across a much broader institutional and retail portfolio.
• Nomura Securities: Japan's largest securities house and a global investment bank. Competes in retail brokerage and investment trusts but primarily serves institutional and high-net-worth segments; broader incumbent rather than direct online-broker competitor.
• Mitsubishi UFJ Morgan Stanley Securities: MUFG group affiliate focused on affluent retail and discretionary wealth management (including Mirai Value wrap referrals from Kabu.com). Not a direct online-broker peer but the sibling MUFG entity for higher-tier wealth products, creating both internal complement and potential cannibalization.

Direct peers

• Matsui Securities: Pioneer of Japanese online brokerage (one-share unit trading). Direct competitor on beginner-friendly retail platform with similar multi-asset offering and zero-commission promotional positioning.
• Rakuten Securities: Top-tier Japanese online brokerage within Rakuten Group, leveraging Rakuten ecosystem (Rakuten Bank, Rakuten Card, Rakuten Pay) for distribution. Direct competitor on multi-asset platform and ecosystem-driven zero-commission positioning.
• DMM Securities: Japanese online broker with strong FX/CFD positioning and competitive point-based incentive campaigns. Direct competitor on zero-commission retail platform, particularly for active FX/CFD traders.
• SBI Securities: Japan's largest online brokerage by accounts and assets, offering a near-identical product suite (domestic/US stocks, FX, investment trusts, NISA, iDeCo). Most direct head-to-head competitor for Japanese retail investors across all asset classes.
• Monex, Inc. Japanese online brokerage group (Monex Securities + Coincheck crypto + TradeStation US). Comparable in multi-asset, multi-channel positioning with US-stock and algo-trading capabilities for active Japanese retail investors.

Emerging players

• moomoo Securities (Japan): Futu-backed Japanese online brokerage offering mobile-first global multi-asset trading and social-investing features. Emerging challenger targeting younger, mobile-native active traders that overlaps with Kabu.com's active-trader segment.
• PayPay Securities: SoftBank/Z Holdings-backed online brokerage leveraging PayPay payment ecosystem. Emerging direct competitor focused on mobile-first UX, fractional shares (PayPay Stock), and ecosystem-driven customer acquisition.
