Architecture and Design
Architecture, equipment and design features
The museum entrance and a grid-like façade present the Museum Tower Kyobashi’s new identity. The museum occupies the 1st to 7th floors, with viewing galleries on the 4th to 6th floors and the museum offices on the 7th.
The gallery space is approximately 2,100 ㎡ , roughly twice the total area of the old museum. A vertical layout of galleries, museum shop, café and museum offices signifies a museum in a new urban style.

Measures to ensure business continuity
To minimize damage in the event of a disaster and ensure business continuity, a seismic isolation structure was adopted for Museum Tower Kyobashi. Emergency generators that can supply power for 72 hours have been provided for use in the event of a power outage. The substation equipment, emergency generators, heat source equipment have been placed on the 8th and 9th floors of the building so building functions can be maintained even in the event of flooding, tsunami or other water damage. Moreover, the art galleries have been placed on the 4th through 6th floors to ensure the safety of the artworks. In this way, the infrastructure itself is designed to enable the art museum to continue to function.

The creation of open spaces
Relocation of art museum front entrance
The front entrance of the former art museum which faced Yaesu-dori has been moved to the Chuo-dori side which is the main street. In addition, an open plaza has been placed at the entrance to give the museum an intuitive and welcoming design.
1st and 2nd floors integrated through enclosure with large glass windows
The 1st and 2nd floor area that constitutes the museum entrance has been enclosed with highly transparent eight-meter-high glass windows, forming an integrated open ceiling design and creating an atrium whose interior is visible from outside. Among these windows, the nine large glass doors in the cafe area on the 1st floor are motor-operated and can be rotated to connect the interior and exterior and create an open cafe with an even greater feeling of spaciousness.

State-of-the-art displacement air conditioning system for galleries
The galleries have a new displacement air conditioning system that uses the flooring joints (5 mm) as vents. Fresh air that is temperature- and humidity-controlled is emitted gently from the entire floor, pushing up the upper air so it can be ventilated from the ceiling. The system is highly energy-efficient and that is both people- and artwork-friendly, achieving an interior environment that has no noticeable air currents or temperature and humidity unevenness.
Specially designed LED spotlights
The Artizon Museum worked with the Yamagiwa Corporation to develop high-quality LED spotlights that provide flexibility to gallery lighting and present the artworks in optimal lighting. The spotlights use ultra-high color rendering VIOLEDs (purple LEDs) that can be dimmed and color-adjusted (2,700K – 4,500K). Wireless system control makes it possible to control the spotlights individually using a tablet, making adjustment easy in galleries with high ceilings. These next-generation spotlights strike a balance between design elegance and meticulous control that is user-friendly.
Advanced display cases
In addition to expanding the genres for artwork exhibition, the Artizon Museum also has an area on the 4th floor to house display cases for exhibiting antiquities and the like. The integrated display case of highly transparent laminated glass have a heretofore unprecedented length of 15 meters, making this space an ideal and seamless environment for appreciating Japanese screens and other works in the collection. The display case also have built-in organic electroluminescent (EL) and other cutting-edge lighting systems to enable artworks to be exhibited in an ideal lighting environment.

Digitalization
The Ishibashi Foundation has been working to digitalize both the collection and related information. In 2016, an IT Project was initiated to ensure that information is managed safely and improve operational efficiency, and to study mechanisms and infrastructure that would make it possible to provide data in an open manner to stimulate the intellectual creativity of visitors. As a result, a data archive was created for the artworks in the museum’s collection and museum exhibitions, etc., and a system (cloud environment) was established to link this information and make it available.
Free WiFi available throughout the museum
Visitors can view a wide variety of high-definition images and data about the museum’s collection and exhibitions using the terminals in the Info Room on the 4th floor, as well as by viewing the Digital Collection Walls on the 4th and 5th floors. WiFi is also available throughout the museum, and visitors can download the Artizon Museum app and use their smartphones to access an audio guide and explanations of the artworks.

Ensuring that the Artizon Museum remains on the cutting edge
Recently there has been a trend toward “Open Data Innovation” in which organizations make their data publicly available to encourage widespread access. The Artizon Museum is working to compile databases with this goal in mind. Moreover, based on its concept of “Experiencing Creativity”, the Artizon Museum will also combine the data with state-of-the-art technology to create a cloud computing environment that will enable various exhibitions and special projects.
Crystal LED Display
Use of digital signage
Digital Collection Walls created by teamLab Inc. that enable visitors to intuitively experience the Ishibashi Foundation collection have been set up in the exhibition lobbies on the 4th and 5th floors. There is also a Crystal LED Display (made by Sony Corporation) in the 1st floor entrance lobby that allows visitors to view ultra-high-definition images of artworks and other information on a large screen.
Carefully selected materials and attention to detail
Exterior design
The exterior design has been given a universal design with a particular emphasis on striking a balance between modernity and harmony with the buildings on Chuo-dori. Latticework befitting the face of an art museum and walls of steel panels that have been treated with phosphoric acid have been used to depict a feeling of authenticity using colors and textures reminiscent of materials such as roof tiles and inkstone.
Stone wall pattern and cylindrical columns
Cylindrical columns measuring 1.8m in diameter and 8m in height, with the same square pattern of granite stones as the wall of the 1st floor entrance, were placed outside. These continue into the interior as stone column artworks that appear in the 16.5-meter-high atrium open ceiling that spans the 3rd to 5th floors. Each column resembling a single large enormous trees that seems to pass straight through the building, making the columns function as a symbol of the Artizon Museum.
Interior design
The interior materials have been carefully selected to express modernity and human warmth, in order to give the museum an atmosphere of friendliness and openness.
Large terrazzo tiles (1F)
Large terrazzo tiles (1,200 mm square) were used for the flooring material on the 1st floor to create the impression of lines running across the floor. Black granite and Indian sandstone and other natural materials were used for the 1F walls. The subtle changes in the finish of the stone surface give the walls an overall softness.
Brass cut panel walls
Wall panels (3F – 6F)
Vibration-polished brass panels were used for the wall panels on the 3rd through 6th floors to give the interior a soft warmth and a golden brilliance. These panels were used on all floors as a distinctive design element. For the lights, a decisive factor for the interior design, wall indirect lighting was adopted, so the wall surface would be illuminated by gradations of soft light. This provides an added three-dimensional resonance and depth and emphasizes the continuity with the entire space.
Original furniture design
As with all other design elements in the building environment, the furniture is based on original design. From the wooden armchairs that are used primarily in the cafe, to the sofas in the galleries that allow visitors to sit on all four sides, to the built-in furniture, all of the furniture has been carefully designed for use in an art museum.
The Design Collection
The Artizon Museum has a design collection that can be seen nowhere else. One of its highlights is the display of furniture by Kuramata Shirō (1934-1991), a leading figure in interior design in Japan. Those works are placed in the lobby at the entrance to the 6F Gallery, where anyone can sit on them. His single-seater sofas (armchairs) made of expanded metal and “How High the Moon,” his famous two-seater copper sofa, await you. They are joined by a semicircular glass bench that has almost never been on display.

Sign planning
An original sign system that includes pictograms was developed for the art museum, both to guide visitors and to serve as an important architectural accent. Innovative ultra-thin slit lights that employ LEDs ensure that text and pictograms stand out, making them easier to see and lending a gentle touch to the interior.
Creating a safe and comfortable viewing environment

IPM cleaning and environmental study
Beginning July 9, a special cleaning process that took approximately one month was conducted to remove the accumulated dirt and dust generated by the construction from the galleries on the 4th through 6th floors and the temporary artwork storerooms and so on. The cleaning was based on the Integrated Pest Management (IPM) approach, which is designed to minimize the impact on human beings and the environment. The process minimized the emission of chemical substances that might affect the artworks and prevented the propagation of insects that might harm cultural artifacts.
The cleaning process resulted in a clean environment for the exhibition of artworks. The National Center for the Promotion of Cultural Properties has been contracted to conduct environmental studies of the galleries and temporary artwork storage and so on. The results of air quality studies and temperature and humidity studies are reported on an ongoing basis, and advice and recommendations are solicited. In addition, in preparation for the museum’s opening, the Center conducted a site survey on August 29 to ensure that the environment is optimal for storing and exhibiting cultural artifacts.
Reservation system introduced
To reduce visitor wait times and create a more pleasant viewing environment, it adopted the museum’s online reservation system to reserve a time for viewing the exhibitions.
Introduction of hazardous substance detection gate system
To safeguard the artworks and ensure visitor peace of mind during viewing, a body scanner for detecting hazardous substances (manufactured by Evolv Technology Inc.) has been placed in front of the elevator on the 3rd floor. This scanner detects metallic hazardous substances and also includes the world’s first system for the detection of nonmetals and liquid explosives using millimeter waves.
Development of general use crates
The Art Research Center (ARC) established by the Ishibashi Foundation in May 2015 stores artworks and materials, conducts research into works of art, performs restoration of artwork and so on.
Recently, working in cooperation with Yamato Global Logistics Japan Co., Ltd., the Center developed an environmentally friendly zero emissions reusable general use crate for transporting artworks. Following a trial-and-error process to determine specifications and material safety performance, a metal (aluminum) “F-20” size crate was completed. The crate was used to transport artworks in preparation for the opening exhibition.
