*On the Fundamental Plan for Constructing the Tokyo City Hall
Drafters of the Fundamental Plan expected the development of Tokyo into a multi-center city, through the activation of its districts harmonized with their respective characteristics. They also contemplated the creation of the new face of Tokyo as an international city, based on its history and tradition. In view of these points, the Plan envisaged the construction of new offices of the Tokyo Metropolitan Government in the Shinjuku district, and present Tokyo International Forum in the Marunouchi district.

Measures for the Environment

Basic Principle

Tokyo International Forum, a leading convention and art center which aims to offer the best in quality and services, positions action on environmental issues as one of its foremost management priorities. We actively engage in activities to reduce environmental impact and help conserve the environment, and try our best to make sustainable society a reality.

Action Policies

To lessen environmental impact, Tokyo International Forum follows these policies:

  1. 1. Observing the relevant laws and statutes related to environmental preservation.
  2. 2. Keeping environmental considerations in mind regarding facility operation, maintenance, overhaul and improvement; reducing resource and energy use; and taking active measures to mitigate the heat island effect.
  3. 3. Doing our best to reduce waste and actively use “green” products and services.
  4. 4. Keeping the public informed and promoting closer communication about our environment-related activities.
  5. 5. Putting in place a framework for promoting environmental measures and making employees more environment-conscious through environmental education.

Specific measures and activities: list of examples

Tokyo International Forum lessens environment impact in a variety of ways.


Tokyo International Forum Improvement Work

Tokyo International Forum opened in January 1997. Since 2009, a 10-year improvement effort has been under way.
The work is not aimed simply at restoring elements of Tokyo International Forum that have aged over the years to their original condition. We aim to add new value in response to contemporary needs, including those of customers seeking the most advanced facilities for the dissemination of information, while reducing CO2 emissions through the installation of environment-conscious equipment.
Following is a list of major renovation projects initiated to date.

Glass Building structural element accent lighting renovation
Glass Building slope lighting renovation
Hall E lighting renovation (all 2009)

The Glass Building is Tokyo International Forum’s most impressive structure. By introducing LED lighting, we hope to eliminate 180 tons of CO2 emissions annually without compromising the original lighting design.
(Part of the Glass Building’s lighting is currently switched off to conserve energy.)

Glass Building conference room air-conditioning system renovation (2009)

We are upgrading the function of ventilation, heating, and cooling systems in the conference rooms while aiming for an annual reduction of 35 tons of CO2 emissions.

Hall A audio equipment renovation (2009, 2010)

All hall speakers were replaced in a two-stage renovation, resulting in a clearer, fuller audio environment.

Hall D1 renovation (2010)

This hall was completely reborn, with conversion from a 132-seat theater space to a 137m2 versatile hall that is ideal for seminars, meetings, and lectures, as well as exhibitions and other uses.

Hall improvements (2011)
  1. 1. Hall E: Audio and electrical systems, full floor repainting
  2. 2. Hall D7: Audio, lighting, and electrical systems
  3. 3. Hall D5: Audio, lighting, and electrical systems
Structural restoration to original condition (2011)
  1. 1. Glass Building internal bridge
  2. 2. Glass Building lounge
  3. 3. Glass Building slope
  4. 4. Plaza (Hall Building side) and Glass Building outside wall
  5. 5. Plaza columns

We will continue these improvement efforts to enable our visitors to enjoy Tokyo International Forum in safety and with peace of mind and comfort.
