Concept & Design Philosophy of New Headquarters Building

Tokio Marine Holdings, Inc. (President and Group CEO: Satoru Komiya, "TMHD") and Tokio

Marine & Nichido Fire Insurance Co., Ltd., (President: Shinichi Hirose "TMNF") are pleased to announce the concept and design philosophy of the new headquarters building ("the Building") *. The Building which is planned to be completed in 2028, will be constructed aligned with, and symbol of, our sustainability strategy.

*We announced the reconstruction of current headquarters buildings on March 25, 2021.

The building will be built in the same location as our current headquarters, in the heart of Marunouchi between Tokyo Station, the gateway of Japan, and the world-renowned Imperial Palace. The design will aim to be refined and elegant and exist in harmony with the beautiful surrounding townscape which is known for business, history, and culture.

As an insurance group, we aim to realize a safe, secure, and sustainable society with strong local communities and the design of the building will reflect these ambitions. It will have the highest level of protection against natural disasters, while also providing an environment that facilitates new and flexible working styles. It will also aim to minimize its impact on the environment, both by reaching the highest standards of environmental efficiency while sourcing environmentally friendly material wherever possible, especially domestically produced wood.

1. Concept of the Building

• Highest Level of Disaster Protection

• Comprehensive range of measures against natural disasters will be adopted such as base isolation, flood barriers, emergency generators and so on in order to ensure our business continuity so that we can fully serve our customers in their time of need
• We will contribute to regional disaster support by creating large indoor space such as an atrium, which can be used to accommodate people who have difficulty getting home in the event of a disaster.

• Maximize Usage of Japanese Wood

• Wood is an "eco-friendly material" because it is a renewable resource and prior to harvesting it helps to reduce carbon in the atmosphere. We have been considering how we can maximize the use of wood in the Building since the beginning of the project.

• The Building will utilize unprecedented amounts of Japanese timber in various parts of the Building including its structure such as columns and floors and we aim to build world largest hybrid wood structure office building.
• By using Japanese wood, which is made of trees that have been largely planted after World War II and is now ready for use, we will support the cycle of afforestation, logging, utilization, and reforestation as consumers, and contribute to the realization of a recycling-based society by conserving forests and water resources, and revitalizing local economies.

• Highest Level of Sustainability

• In addition to reducing the carbon footprint by using wood, we will conserve energy and reduce operational carbon emissions of the Building by introducing highly efficient facilities and zoned heating and cooling systems.
• We aim to source 100% renewable electricity for all of the electric power used in the Building.
• Rooftops will be greened to conserve biodiversity and mitigate the heat island phenomenon in the city. In addition, public spaces will be set up on the first floor to provide local residents with a place to relax, in order to improve the urban environment.
• We will conserve water resources by utilizing rainwater for gray water and introducing a water recycling system.
• We aim to achieve the highest level of Platinum certification in LEED, an international green building certification program.

• Flexibility for New Working Styles

• By replacing the two current buildings into a single structure, the Building will have a large footprint with a lot of flexibility to facilitate diverse ways of working.
• Each office floor will be connected by inner staircases in order to enhance communication beyond organizational boundaries to enable synergy so that we can provide more value to our customers and society.
• We will have an open atrium to provide natural light inside, a roof garden and health clinics to create an environment in which employees can work with high performance and in a healthy way as part of our commitment to health and productivity management.
• The Building will be universal design, in order to ensure all occupants can use it comfortably regardless of age, disability or other factors.

2. Architectural Design

• TMNF has engaged with Renzo Piano Building Workshop SAS*1, which was established by world-renowned and Pritzker Prize laureate architect, Renzo Piano and Mitsubishi Jisho Sekkei Inc.*2 as the architects of the Building. With the cooperation of the two companies, we are promoting many unique and innovative ideas, including the use of Japanese wood.
• Regarding the current main building (completed in 1974 and designed by Kunio Maekawa),

TMNF will work to create a visual record to preserve its historical value and pass it on to future generations.
