              Organization of MTFG's Integrated Business Groups and
                   Introduction of an Executive Officer System

Tokyo, March 29, 2004 --- Mitsubishi Tokyo Financial Group, Inc. (MTFG;
President: Shigemitsu Miki) today outlined the organization of its Integrated
Business Group system comprising three core business groups: retail, corporate
and trust assets (asset management and administration) businesses, that will be
introduced from April 1, 2004.

At the same time, in response to the introduction of the integrated business
groups system and to strengthen corporate governance, MTFG will modify and
strengthen the organization of its Corporate Center and introduce an executive
officer system.

1. Organization of the integrated business groups

Details of the divisions of the three business groups and their main planning
and administrative functions are shown in the appendix. Led by a Group Head,
each division will aim to unify business strategy for MTFG as a consolidated
whole, and support enhancements to the speed and consistency of decision making
on a Group-wide basis.

2. Changes to Corporate Center organization

Along with the creation of the integrated business groups, Corporate Center
organization will be modified. Specifically, Credit & Investment Management
Division will be established to create a credit risk control system that
corresponds to the integrated business groups, and that improves and strengthens
Group-wide risk control.

Employee numbers of MTFG, the holding company, are expected to rise as a result
of the inclusion of the integrated business groups and changes to the Corporate
Center, from around 90 at present to approximately 550.

The Integrated Retail Banking Business Group and the Integrated Trust Assets
Business Group will be located in the Mitsubishi Trust & Banking Corporation
headquarters building and the Integrated Corporate Banking Business Group in the
Bank of Tokyo-Mitsubishi headquarters building.

3. Introduction of an Executive Officer System

In order to clearly separate the functions of the oversight of business and the
execution of business and so enhance our corporate governance, an executive
officer system will be introduced along with the integrated business group
system. With responsibility for business planning and administration, the Group
Heads and Deputy Heads of the integrated business groups, as well as the heads
of the main business lines, will be executive officers dedicated to execution of
their respective businesses. In contrast, directors will be responsible for
management decision making and the oversight of business execution.
