TL;DR

Mitsubishi UFJ e-Smart Securities Co., Ltd. (三菱UFJ eスマート証券株式会社) is the online securities operator of the MUFG group. It carries the lineage of the former au Kabucom Securities and, according to public press releases, became a 100% subsidiary of MUFG Bank at the end of 2025 年 1 月 and was renamed “Mitsubishi UFJ e-Smart Securities” in 2025 年 2 月. It is listed in the FSA’s list of financial instruments business operators as a Type I Financial Instruments Business Operator under the Financial Instruments and Exchange Act (Director-General of the Kanto Local Finance Bureau (Kinsho) 第61号).

1. License / group boundary

2. Operating model

Mitsubishi UFJ e-Smart Securities, as MUFG’s online brokerage channel, handles equities, investment trusts, margin trading, futures, FX, and the like. Through the 2025 年 parent-company change (Mitsubishi UFJ Securities HD → MUFG Bank) and the corporate name change from au Kabucom Securities, it shifted from a KDDI flavor toward the MUFG brand. It is a retail online broker layer distinct from the wholesale- and corporate-centered Mitsubishi UFJ Morgan Stanley Securities, while the linkage context with the former au economic sphere remains on the au Financial Holdings (au-FH) side.

3. Why this page matters

• MUFG is a huge commercial bank / trust / wholesale securities group, but retail digital brokerage is a separate competitive axis. An independent page is needed to track the comparison with SBI Securities, Rakuten Securities, and PayPay Securities, bank-app linkage, and NISA account acquisition.
• It records the Type I operator anchor under FSA supervision and the 2025 年 parent-company and name change.
