Ginza Niigata Information Center THE NIIGATA is Niigata Prefecture's information hub for the greater Tokyo area. It spans five floors, from the basement to the third and eighth floors, and is equipped with a variety of functions, including retail, a sake tasting corner, an event space, a restaurant, and an immigration consultation desk. Our company was responsible for the design and construction of the first basement floor to the third floor, as well as the facility branding plan and brand logo development. In addition to showcasing Niigata's rich attractions, such as rice, sake, and snow, we focused our planning and design on concept design. We aimed to create a facility that would allow visitors to experience Niigata's charms and serve as an opportunity to visit the city, with materials and displays originating from Niigata scattered throughout.

Located within the Osaka Healthcare Pavilion at the 2025 World Exposition, Osaka, Kansai, Japan (Osaka-Kansai Expo), this space offers a close-up look at actual myocardial sheets made from iPS cells. A symbolic sculpture has been installed with the motif of a "tree" growing from the seed of iPS cells into a mighty tree, representing the progress of research and development around the world since the discovery of iPS cells and the development of science and technology. Within the "tree" is a giant heart model that moves in sync with the beating of the myocardial sheet on displays, and the heartbeat reverberating loudly in the atrium, along with video effects, express a future where people can live healthy lives thanks to advances in regenerative medicine.

2025年日本国際博覧会（大阪・関西万博）において地球環境産業技術研究機構（RITE）様が出展する実証プラント「RITE 未来の森」において、当社は企画、デザイン、建築、展示設計および監理から運営サポートまで総合プロデュースを行いました。本施設は、大気から二酸化炭素を直接回収するDAC（Direct Air Capture）※1と 、それを地中へと貯留するCCS（ Carbon dioxide Capture and Storage ）※2の双方を掛け合わせることで、今後期待されている未来の技術の実証実験に取り組んでいます。そして、人が排出した二酸化炭素を人の力で回収するという、新しい森を未来につくることを目指したプロジェクトです。ガイダンス棟では建築も新しい技術への実証実験として取り組み、未来の森というコンセプトから未来の木造技術「CLT※3折版構造ハングアップ工法」を世界で初めて実現させました。ハングアップ工法とは、丁番金物によりお互いに緊結した三角形 CLT パネルを水平面に敷き詰め、特定箇所をクレーンで吊り上げることで自重により折り紙のように変形し、折版構造を形成させるコンセプチュアルな工法です。今回はこの工法を用いることで、表情のある構造体で大空間をつくり上げ、デザイン性・機能性・施工性を併せ持ったCLT構造の普及促進につなげるための建築実証プロジェクトとしての側面もありました。これにより、身の引き締まるような神聖な空気感を発する建築空間が出現し、そして国産杉によるCLT折版構造そのものが展示映像や演奏などの音を響かせるコンサートホールのような音響環境を実現した類稀な建築となっています。会期終了後には、サスティナビリティ建築として活用すべく、京都府木津川市にあるRITE本部への移設の計画があります。万博の出展、そしてその後の活用を通し、二酸化炭素排出抑制、廃棄物を最小限とするリユース、CLT構造の普及促進などさまざまな社会課題に取り組みました。※1　大気からCO₂を取り除くことで、大気中のCO₂濃度を下げる技術※2　排出されたCO₂を集めて地中に貯留する技術※3　ひき板を並べた後、繊維方向が直交するように積層接着した木質系材料 

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.

As the host country of the 2025 World Exposition, Japan (Osaka-Kansai Expo), which will be held under the theme of "concept design a Future Society for Life," this pavilion, based on the theme "Between Life and Life," seamlessly connects displays and architecture, allowing visitors to experience the significance of "circulation." The Japan Pavilion, with its circular structure embodying the relay of life, exudes a unique presence as a pavilion of a host country. While the flow of visitors is naturally drawn into the pavilion as they walk around it, its most distinctive feature is the countless wooden planks arranged in a circular pattern. The gaps between these planks allow visitors to glimpse the interior, and the continuity between inside and outside, displays and architecture, encourages visitors to become aware of the "in-between" aspect of the pavilion's theme. Another unique feature of this pavilion is the concept of a "Japan Pavilion that eats garbage." Microorganisms will decompose waste generated within the Expo site and convert it into energy and water. This "living pavilion" allows visitors to relive this process through an installation* and experience how the energy and water generated power the Japan Pavilion. By circulating the three-zone pavilion, visitors can sense the significance of "circulation," a Japanese aesthetic, and truly feel part of this long and magnificent story. Additionally, by using primarily cross-laminated timber (CLT) as "wooden boards" and steel for the structure, the pavilion uses CLT in as simple and symbolic a way as possible. The CLT used in the Japan Pavilion is planned for reuse by companies and local governments across Japan after the Expo ends, and has been designed for easy dismantling and repurposing. By understanding the value of "circulation," which underlies the Japan Pavilion's theme, "Between Life and Life," we aim to encourage visitors to reexamine the circulation that surrounds us and explore the future of society and hints for a sustainable future. Our company is responsible for displays concept design (schematic design, working drawings), construction, and operation of the Japan Pavilion. *A contemporary art form in which the entire displays space is experienced as a work of art. The audience walks around the space and enjoys the work through sights, sounds, and more.

This pavilion for the Osaka-Kansai Expo uses realistic materials to express the rich stories of Qatar's people, land, and sea. The space is composed of real sand that recreates the desert landscape with delicate gradations, aluminum that resembles the deep sea covering the floor, walls, and ceiling, and a giant curtain with intricate embroidery that symbolizes the country's cultural richness. We designed an experiential displays space in which Qatar's traditional crafts and landscapes emerge in a fantastical way amid materials that directly appeal to the visitor's sensibilities.

Lawson's new store, opening within the 2025 World Expo, Japan site, is located in front of the East Gate entrance, which is directly connected to Yumeshima Station (Osaka Metro Chuo Line), the closest station to the site.

At the same time, it also serves as a base facility for the local Minami Town's plan to increase the return rate of sea turtles. This renovation has created a place where people can learn about the coexistence of humans and nature through sea turtles and nurture the next generation of leaders by providing a comfortable space for visitors and making it easy for sea turtles to live in from the perspective of animal welfare.

The Malaysian Pavilion, exhibited at the 2025 World Expo in Japan (Osaka-Kansai Expo), is a space that comprehensively expresses the tradition, diversity, and advanced nature of the multi-ethnic nation of Malaysia, with the theme of "INTERWOVEN - Weaving a Harmonious Future." At the center of the pavilion is the symbolic "Tree of Harmony," about 10 meters tall, whose leaves are hand-woven by artisans from all over Malaysia using sustainable natural materials, and whose trunk is an organic structure made by weaving fast-growing bamboo in a spiral shape. The morphological language of this design is also deployed in displays floor, lighting, and graphics, symbolizing the network that weaves the entire pavilion. As a pavilion where diversity intersects to weave one big story, it has become a place that embodies hope for a harmonious future.

The venerable RIHGA Royal Hotel Osaka, which has a history of 90 years since its founding and has been loved by many guests, including state guests and the Imperial family, as the "Guest House of Osaka," has introduced the "Vignette Collection," one of the brands of IHG Hotels & Resorts, and has made its grand opening as the "RIHGA Royal Hotel Osaka Vignette Collection" in preparation for the opening of the Osaka-Kansai Expo in April 2025. The hotel has been renovated into a space that will be loved for generations to come, inheriting the hotel's history and identity and incorporating the charm of the beautiful surrounding scenery unique to the city of water.

The Panasonic Group Pavilion "Nomo no Kuni" is a pavilion based on the concept of "Unlock your nature" that draws out the potential of children through sensory analysis technology and experiences that stimulate the five senses. Utilizing the latest technology from Panasonic Holdings, we have achieved a spatial design that harmonizes with the worldview of "Nomo no Kuni" by using tiles that evoke the tactile sensation of walking on natural ground, natural wood finishes with metallic textures, and concept design techniques that combine with 3D printing. We adopted a spatial and experience concept design approach centered on what we can do for the future of children, incorporating cutting-edge design and construction methods in sustainability, such as reusable tiles and biodegradable concept design printing.

Founded in Nagano in 1736, Yawataya Isogoro is a long-established company that has created the image that "Shichimi is the best Shinshu souvenir."
