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.

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.

We renovated the Mountain Center, located at the base of the Niseko Tokyu Grand Hirafu slopes in Abuta District, Hokkaido. The facility consists of two floors: a shop and ticket counter on the first floor and a restaurant on the second floor. The renovation expanded the first-floor sales floor by 1.6 times, and the second-floor restaurant, renamed "sanshoku," underwent a complete redesign along with its spatial presentation. The design interpreted the facility as a place to see off guests arriving at Grand Hirafu and onto the slopes, and a place to welcome guests returning from the slopes. By blending the generous, concept design nature of Hokkaido with the newly enhanced, cool brand identity symbolized by "Hirafu Blue," and sprinkling these elements into the vibrant, one-of-a-kind atmosphere unique to resort facilities, we aimed to create a space that offers a unique, cool yet warm experience.

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.

Spread out in front of the Koitoi coast in Hokkaido, "Roadside Station Shiranuka Koimunkan" is a facility where you can enjoy a comfortable car trip with a function as an RV park (*1), which is rare at a roadside station, and is equipped with showers, saunas, and laundromats. There are also restaurants that use local ingredients from Shiranuka Town, and on a clear day, you can overlook the beautiful scenery of the Koimun Coast from the "Azumashi Living" with a view of the sea and the observation deck on the second floor. In addition, based on Shiranuka Town's idea of "supporting child-rearing in Japan", the facility is equipped with a children's family space (Kokko Park). We participated mainly in the planning work of this project as a consortium member, and after being commissioned, we promoted the work as a member of the construction JV (*3), and handled a wide range of tasks such as interiors design and sign planning.  *1 A sleep-in facility certified by the Japan RV Association. *2 DBO (Design, Build, Operate): One of the public-private partnership methods in which design, construction, maintenance, management, and operation are comprehensively ordered from private companies. *3 Joint venture system. A business organization formed by multiple companies for the purpose of receiving and construction a single construction project.

Located at the gateway to the "Umekita Phase 2 Area," Umekita Green Place is a commercial complex themed around "greenery" and "a place for encounters and interaction." We proposed creating a facility with 20 stores, primarily restaurants and cafes, that would create a lush green plaza and a lively, relaxing space where visitors can wander around and enjoy themselves, catering to the needs of people passing through the JR Osaka Station area for a variety of purposes, from nearby office workers to people visiting the park or shopping. We were responsible for the planning, design and construction of the food court on the second floor and the restrooms on the second and third floors, as well as furniture and fixture manufacturing of the entire facility.

We were responsible for design, layout, sign and graphic concept design, interior administration, furniture and fixture manufacturing, environmental features, and construction of the restaurant "Lounge & Dining" at the 2025 World Exposition, Japan (Osaka-Kansai Expo). This facility is concept design to be a "place of hospitality" welcoming guests from Japan and abroad, and combines high-quality spatial presentation with comfort. We aimed to create a space that would create a memorable and special experience for people gathering from all over the world.
