    Head Office of Hakusuisha, Inc.

    Good Design Award

    Hakusuisha is a comprehensive display company that has been designing spaces for many years. When deciding to relocate its new head office to mark the milestone of its 75th anniversary, it chose Nihonbashi Kabutocho, a district being redeveloped by Heiwa Real Estate.

    Comment from Evaluation Bodies

    Firstly, the entrance hall, where visitors are welcomed by a pit-shaped staircase, is truly impressive. The narrowing of the entrance created by the pit, along with the security gate installed in the bottlenecked space, results in a highly logical and efficient layout. On the first floor, the workplace extends toward the back, with floors at varying heights that respond to the pit and staircase, gently dividing the space and offering a variety of areas. One can easily imagine a dynamic work environment where employees select the most suitable space based on the tasks they are engaged in at the time. In contrast to the first floor, the basement level presents a completely different atmosphere with its bright, white interior, likely encouraging a shift in work mode for employees. This workplace, filled with a variety of stimulating elements, is undoubtedly deserving of a Good Design Award.

    Kabutocho Heiwa Building No. 7

    Good Design Award

    Previously used as a bank, the Kabutocho Heiwa Building No. 7 has been remodeled as retail space inside, and part of its structure has been removed to create an outdoor area. Original materials and traces of a demolished staircase have been left intact, while the building’s metal railings with botanical patterns, granite floors, and old address sign have been refitted. The plan incorporated local recycling by reusing timber formwork used for constructing the new KITOKI building nearby, as well as a locally inspired design of copper sheets attached to ceilings, representing the surface of the Nihonbashi River. Benches and counters have been arranged in spaces that encourage a variety of activities and make it easy for anyone to drop by and meet people, enjoy friendly chats, and buy coffee and bread.

    Comment from Evaluation Bodies

    When I had come across this building in the past, I was aware that Kabutocho has been changing. Still, this building is an example of how the neighborhood is coming alive organically not only through large-scale redevelopment but also through a combination of small-scale projects. Rather than concentrating many stores in the building, which is typical of big redevelopment projects, this one features a ‘street corner’ space. The outdoor area was opened up by removing parts of the structure, and materials were reused to create tactile textures and evoke the building’s historical background. By bringing together these small elements of time and history, the designers succeeded in creating a place where people can feel a sense of belonging. Generally, cities develop in layers over time, and this project demonstrates how realizing that concept appeals to many people. It shows the potential for developing our cities like the way trees are grown through grafting.

  • Edible KAYABAEN

    Good Design Award

    Edible KAYABAEN is a sustainable urban gardening project that transforms an unused building rooftop, covering approximately 600 square meters, into a garden growing over 200 varieties of edible plants. In addition to promoting urban greenery, the project aims to address issues and foster prosperity in Tokyo’s Chuo Ward by offering regular opportunities for community engagement, particularly through food education activities for children.

    Comment from Evaluation Bodies

    Rooftop vegetable gardens utilizing rooftop spaces in urban areas have been increasing across Japan, but what distinguishes this initiative is its ongoing commitment to food education. In addition to growing, harvesting, and preparing food, it has developed an observational learning program offered to many children living in the city. The project also includes a sustainable recycling model, such as composting. As various layers of the city are continually reimagined as an Edible City, we hope that this initiative will extend beyond the rooftop and expand to the ground floor of the building as well.

    KITOKI

    Japan Wood Design Award

    KITOKI is a 10-story commercial and office building that integrates a wooden structure within a three-story steel-reinforced concrete megastructure, pioneering new possibilities for the use of wood in urban environments. The combination of concrete’s century-long durability and the lightness of the wooden structure creates innovative opportunities for incorporating wood into urban architecture.

    Comment from Evaluation Bodies

    This project is unique in that it encases a wooden structure within a steel-reinforced concrete frame. By leveraging the design expertise and characteristics of wooden houses, the designers have successfully created varied space layouts on each floor, giving the building the appearance of a low-rise wooden structure.

  • The HEART

    International Design Excellence Awards

    The HEART is a digital signage installation that symbolizes the circulation of blood through the Japanese economy, with the heart as its source. Featuring an iconic cubic LED display with rotating components, The HEART is one of the largest LED displays in the world, measuring 6 meters in width, 5.5 meters in height, and 3 meters in depth. It processes stock data in real time and translates it into abstract representations of the heart, enabling viewers, even those unfamiliar with stocks and economics, to intuitively grasp the cycle, pulse, and energy of the Japanese economy.

  • The HEART

    Digital Signage Award 2022

    The three-dimensional, movable LED signage is the first of its kind in Japan, making a significant impact. While there are location constraints, it offers a wide variety of information, and it is expected that this type of signage will become more widespread in the future. The design-focused LED casing, which is earthquake-resistant and heavy-duty, must have posed substantial challenges. I was impressed by how the content utilizes topics that represent the Japanese economy, creating a highly original media experience. The shape and concept are exceptionally unique, and the interface of information, tailored to the segmented movable area, is particularly intriguing.

  • The HEART

    Red Dot Design Award 2022

    In 2022, The HEART received the prestigious Red Dot Design Award in the Interior Design Elements category of the Product Design discipline. One of the world’s largest cubic-shaped LED displays, The HEART is installed in the first-floor atrium of KABUTO ONE, a large multi-purpose building.

    The HEART

    Good Design Award

    Created in 2021, The HEART symbolizes the flow of blood circulating through the Japanese economy, with its source in Nihonbashi Kabutocho—a historic area known for innovation, investment, and stock trading. Since the Meiji period, when Eiichi Shibusawa established Japan’s first stock exchange and bank, the area has played a pivotal role in Japan’s financial history. Featuring an iconic design and one of the world’s largest rotating LED displays, The HEART has become a new symbol of this area.

    Comment from Evaluation Bodies

    The HEART is one of the world’s largest rotating LED displays, and thanks to its location at a street corner, it commands an impressive presence and powerful information delivery. Although Nihonbashi Kabutocho is inevitably losing some of its vibrancy as a financial district due to the closure of the Tokyo Stock Exchange trading floor, The HEART captures the desire of those involved in the exchange to convey the area’s significance and history to visitors. By visualizing the energy of stock trading, which has become harder to grasp since its digitalization, The HEART brings this history to life. We also appreciate the display’s name, as it likens the market’s sensitivity to world affairs to the beating of a heart. We hope that the dynamic images displayed by this massive, moving structure will become a new symbol of Nihonbashi Kabutocho.

    Kabutocho Heiwa Building No. 5

    Good Design Award

    Nihonbashi Kabutocho evolved as Japan’s center of innovation, investment, and stock trading, with its history dating back to the Meiji period, when Eiichi Shibusawa established the country’s first stock exchange and bank. The Kabutocho Heiwa Building No. 5 was completed in 1923. In 2019, the steel panels that had covered the building for 31 years were removed, restoring its facade to reflect the style of Japan’s Taisho period (1912-1926). Today, it operates as a multi-purpose commercial facility.

    Comment from Evaluation Bodies

    Completed in 1923, the year of the Great Kanto Earthquake, this bank annex building has been renovated, with its façade restored. The restoration preserved various vestiges added over the past 97 years, while maintaining the architectural style of the Taisho period. Rather than emphasizing the building’s historical and symbolic aspects, the restoration aimed to highlight its long-established presence in the area. Notably, the renovation of this relatively small building marks the beginning of a process to design a local hub, preceding a larger revitalization project covering approximately 10 hectares.

Professor Igarashi’s Insights

I have walked through Tokyo’s neighborhoods many times in search of buildings to feature in the monthly magazine Gekkan Nihonbashi and for an exhibition I curated at Takashimaya Archives Tokyo titled Unraveling Further Ornamentation (Sarani Soshoku wo Himotoku). In Nihonbashi Kabutocho, I am impressed by how redevelopment projects differ from those in other areas of Tokyo, with many top-grade designs placing great importance on local history. Among them, I noticed several fascinating projects in Kabutocho that emerged during the COVID-19 pandemic. For example, in 2021, the changeable cube-shaped display The HEART was suspended inside the atrium of KABUTO ONE. A building originally constructed as a bank in 1923 with a classical facade was renovated into a hotel, K5, in 2020. Completed in 2022, KITOKI is a hybrid structure incorporating wood as a primary building material, while the facade of Kabutocho Heiwa Building No. 7 was significantly reduced in 2022 to create a public space on a street corner.

In addition, when I served on the jury for the 2024 Good Design Award’s Industry and Commercial Facility category, I encountered the attractive interior of Hakusuisha’s head office, which had been submitted as an entry after its completion in 2023. Later, I discovered that all of these buildings were developed by Heiwa Real Estate, headquartered in the Nisshokan Building, which brought Italian palazzo-style architecture to Kabutocho when it was completed in 1928. Incidentally, all five of the projects I mentioned have won Good Design Awards. Armed with a map of Heiwa Real Estate’s projects, I explored Kabutocho and found many more renovated and newly built buildings scattered throughout the area. Some of them were places I had been curious about, and eventually, everything seemed to fall into place. While it can’t be seen from the street, Edible KAYABAEN is a vegetable garden offering hands-on food education on the rooftop of the Tokyo Shoken Building. This project has also won a Good Design Award.

These projects are not about completely redeveloping entire city blocks and constructing high-rise buildings to dramatically change the cityscape. Most of the projects in Kabutocho are not large-scale, but they effectively update the area by tapping into its potential. As the birthplace of banking in Japan, Kabutocho has strong historical ties to Eiichi Shibusawa, who was chosen to appear on the country’s new banknotes. Today, however, the area is being transformed into a vibrant hub for high-end restaurants, galleries, and startups. While redevelopment projects have gained attention since the turn of the century, it is rare to see a single real estate developer focus on so many small-scale projects within a specific area of Tokyo. Rather than leading to a greater number of similar developments, this approach has fostered a series of unique projects that enhance the potential of their locations and create synergistic effects. This design approach is well-suited to the historic character of Kabutocho.
