Located in Shimonoseki City, Yamaguchi Prefecture, Kaikyokan is a popular aquarium that displays a wide variety of pufferfish, a unique feature of Shimonoseki, as well as one of the largest penguin displays in Japan, and is known for its "Lifestyle displays" that focus on the natural habits and behavior of animals. This is the first major renovation since the aquarium opened, and involved updating and renovating aging facilities, while also renewing displays. In addition to the novel concept design meets the expectations of visitors to the facility, which is beloved not only locally but also widely in the Chugoku and Kyushu areas, the structure also places emphasis on functionality.

At the demonstration plant "RITE Future Forest" exhibited by the National Institute of Global Environmental Technology (RITE) at the 2025 Japan International Exposition (Osaka-Kansai Expo), we provided comprehensive production from planning, concept design, architecture, displays design and supervision to operational support. The facility is engaged in demonstration experiments of future technologies that are expected in the future by combining both DAC (Direct Air Capture)*1, which directly captures carbon dioxide from the atmosphere, and CCS (Carbon dioxide Capture and Storage)*2, which stores carbon dioxide directly from the ground. This project aims to create a new forest in the future, by capturing carbon dioxide emitted by humans with human power. In the Guidance Building, we also worked on architecture as a demonstration experiment for new technologies, and realized the world's first future wooden construction technology, the CLT*3-fold structure hanging method, based on the concept of the forest of the future. The hang-up method is a conceptual method in which triangular CLT panels that are tightly connected to each other by hinge hardware are laid on a horizontal surface, and a specific part is lifted by a crane to deform it like origami under its own weight to form a folding plate structure. This time, by using this construction method, it was also an architectural demonstration project to create a large space with a structure with an expressive expression and to promote the spread of CLT structures that have both concept design, functionality, and construction. As a result, an architectural space that exudes a sacred atmosphere that exudes a sense of tightness has emerged, and the CLT folding structure itself made of domestic cedar has become a unique building that realizes an acoustic environment like a concert hall that resonates with displays videos and performances. After the exhibition, there are plans to relocate to the RITE headquarters in Kizugawa City, Kyoto Prefecture in order to use it as a sustainable building. Through exhibiting at the Expo and subsequent utilization, we addressed various social issues such as reducing carbon dioxide emissions, minimizing waste, and promoting the spread of CLT structures. *1 Technology to reduce CO₂ concentration in the atmosphere by removing CO₂ from the atmosphere *2 Technology to collect emitted CO₂ and store it in the ground *3 Wood-based materials made by layering and bonding the ground sheets so that the fiber directions are orthogonal after arranging them.

All floors of Loisir Hotel Shinagawa Seaside are located on high floors, with the reception and conference rooms on the 16th floor and seven floors of guest rooms on the 17th to 22nd floors. For this latest renovation, we were responsible for renovating the 50 guest rooms on the 18th floor. Taking advantage of the hotel's unique location and focusing on its convenient access to tourist attractions, we reflected concept design in the first experience of the stay. Based on the concept of "a space where the first step of a journey begins," we aimed to create a space where guests can feel the hospitality of the hotel by dividing the stay experience into smaller parts and incorporating concept design into that "first action." Furthermore, to take advantage of the unique scenery of the area, we incorporated the colors of the container terminal in the port area in front of the hotel into the FF&E, incorporating the outside scenery into the space as a backdrop.

This is Kawasaki Heavy Industries' displays space at the "City of the Future" pavilion at the 2025 World Exposition, Japan (Osaka-Kansai Expo). displays concept is "Mobility Instinct Laboratory." The Kawasaki Heavy Industries Group's vision of a mobility society in 2050 is expressed through an experiential displays using a full-scale mobility vehicle. Through visitors' experiences of "seeing," "touching," and "experiencing," the space provides a sense of great hope and expectation for the future of mobility. By combining a spatial presentation that combines a futuristic feel with an immersive feeling using large LEDs with displays and experience using a full-scale mobility vehicle, the space allows visitors to experience the future of mobility as if it were their own.

Following the closure of the Panasonic Center Tokyo in Ariake, Tokyo in December 2024, displays for business customers has been relocated to Shiodome, Tokyo, and the Panasonic Corporate Showroom has been reopened as a place where visitors can experience the Panasonic Group's history, latest solutions, and vision for the future. Targeting VIPs from corporations and government agencies, the showroom encourages co-creation through empathy, presenting Panasonic's history and various initiatives for the future through hospitality and video presentations. We were responsible for design, layout, and construction.

This is a Tokyo Head Office relocation project of Toman Toys, which handles the planning, manufacturing, sales, and consulting business of character miscellaneous goods and toys. Against the backdrop of rapid business growth, we started with the aim of expanding our office and rebranding our company, and we were in charge of construction from concept design design to interiors and construction work. Based on the "creative power" and "trust" that Toman Toys has built up so far, we are creating a new face of the company with an eye on future growth while valuing a friendly and soft corporate image. The layout plan reflects the company culture of closeness and friendliness in the spatial composition. concept design used a combination of materials in a one-tone color based on wood to express the intellectual atmosphere of an idea company. In addition, FF&E coordination based on Scandinavian furniture fosters a soft atmosphere of the corporate image. The corporate colors incorporated throughout as accents create a sense of unity throughout the space, creating a one-of-a-kind office.

EARTH MART, the signature pavilion for the 2025 World Exposition in Japan (Osaka-Kansai Expo), was produced by Kundo Koyama. Based on the theme of "Considering Life through Food," it shares the potential of the food culture cultivated by the Japanese people and the evolution of food through technology, creating a space for considering "new ways of eating" that will lead us into the future. The design, which showcases "life" in a supermarket setting typically filled with "food," allows visitors to experience and gain insights into the background of life. Discovering value in everyday scenes provides an opportunity to reflect on the choices we make in various daily situations. Furthermore, the space is constructed using living materials such as "vegetable flowers" and "recycled eggs made from eggshells." The content itself was developed in collaboration with various people involved in food (farmers, sushi chefs, biotechnology researchers), creating an "integrated worldview" that unfolds in the space, thereby conveying its message. By resetting various assumptions through these "fragments of life," visitors can become aware of what is truly important to life, develop gratitude and kindness, and experience a subtle happiness. This product embodies Producer Koyama's desire to leave you with a lasting impression that makes you want to cherish mealtimes just a little more than yesterday.

Osaka Prefecture and Osaka City, hosting the Osaka-Kansai Expo, are exhibiting at the "Osaka Healthcare Pavilion Nest for Reborn," a joint collaboration between industry, academia, and the public sector. As the lead displays joint venture, we were responsible for the master plan, schematic design, working drawings, and construction. The basic concept of the pavilion was to "experience a life where future medical care and healthcare are ubiquitous, while also displays as an experiment in future society that will connect to a legacy." We expressed this concept through the future themes of "healthcare," "city," "food and culture," and "entertainment." The main program, the "Reborn Experience Route," allows visitors to measure their health data with a "Body Measurement Pod" and meet their 25-year-old selves. Together with this 25-year-old version of themselves, they can experience the future of healthcare and urban life envisioned by approximately 20 exhibiting companies, primarily from Osaka, and experience a rebirth of their future selves. This exhibition was created with the hope that it would inspire people to be reborn and take a new step towards a "future society where life shines." [Characteristics of the project] displays was created with the hope that it would inspire people to be reborn and take a new step towards a "future society where life shines." The hope was that it would inspire people to be reborn and take a new step towards a "future society where life shines." This was made possible by bringing together the hopes of the general producer, advisors, exhibiting companies, and many other stakeholders.

This project was initiated to mark the 30th anniversary of Yokohama Landmark Tower. It brings together three attractive bars, including one overseen by a chef with ties to Yokohama and Kanagawa, and another in collaboration with a local company, and opened on May 29, 2025 as a new food hub that will bring the appeal of local food and producers to visitors. Our company was responsible for everything from planning to concept design and construction, with some of the store interiors using wood from Kanagawa Prefecture and the space being decorated with mural art by Kanagawa-based artist Ryohei Yamashita.

Located in Umekoji Park in Shimogyo Ward, Kyoto City, Kyoto Aquarium is a popular social area visited by a wide range of people, from children to adults. We have renovated "Mittete," a new area with a wide range of functions, including displays about the aquarium, workshops, and a place to rest. The space is designed to be a place where visitors can learn not only about the animals, but also about the staff's feelings towards them, and the activities of the staff and the aquarium, making them even more fond of Kyoto Aquarium.
