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.

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.

Tokiwakan, a ryokan inn in Gamagori, Aichi Prefecture, was beloved by many literary figures during the late Meiji period. The Ume Annex, originally built as a detached building, has been reborn as "THE COVE," a Gamagori Classic Hotel accommodation facility, offering a whole-house rental experience. Based on the concept of "encountering the blessings of the region surrounding Mikawa Bay and enjoying them with all five senses," the hotel makes the most of the renowned building, a registered tangible cultural property, and the views it commands, nestled on a hill overlooking Takeshima Island in the tranquil Mikawa Bay. Furthermore, by adding a touch of "newness" where necessary, the hotel creates a pleasant contrast and an extraordinary lodging experience. The hotel is packed with the charms of the region, featuring artwork using traditional techniques handed down in the area and the development of original drinks crafted by local people using local ingredients.

We designed and concept design the entire house, from design administration concept design the interior design and exterior concept design. The site overlooks the Sea of Japan, and the area is known as a scenic spot with a dynamic topography called "cave". On the other hand, if you look at the surrounding area, you will see that the labyrinth-like intricate alleys create a unique streetscape. This is a feature unique to this area, with a square-shaped structure with cranked intersections to prevent the north wind from blowing through. By incorporating this unique alley structure into the ground floor plan, the architectural volume is segmented and harmonizes with the surrounding environment. The exterior and entrance hall are structured like a topography based on the motif of the ria coast, and the continuity with the streetscape is ensured by setting back from the south side. On the other hand, the north façade is raised one step higher than the surrounding area, and has a three-dimensional square-shaped structure intended to prevent the north wind from blowing through to the city. For the exterior finish, in order to echo the external characteristics of the ria coastline, with its rocky surface at the bottom and lush trees at the top, we used rock-like concrete with exposed aggregates for the lower layer, and wood-grain concrete with cedar board formwork for the upper layer. Both the aggregates that appear on the surface and the cedar board formwork materials are made from materials that can be collected in the area, and we hope that the unique expressions of the materials will weave the unique scenery of the location into the future. In addition, by applying this two-tiered structure to the finishes of the interior spaces as well, it creates a sense of unity with the architecture, contributing to fostering a sense of unity between the inside and outside.

This project was undertaken by Takekoma Shrine, one of Japan's three major Inari shrines, to create a lively atmosphere in the local community. Our company acted as the hub, forming a team that united the shrine, the local community, and the company. The team worked on five main areas: "development of the shrine forest," "installation of a cafe," "vitalization of the local community," "promotion," and "creating a new festival." Our company was responsible for the overall production of the project, including planning, logo concept design, design administration, landscaping concept design, construction, exterior construction, cafe opening support, cafe menu development, product development, video production, and PR. Our goal was to ensure that Takekoma Shrine would continue to be an indispensable part of the lives of the local residents and be passed on to the future in a sustainable way. ○ Contents of comprehensive production ① Extraction of customer issues ② Proposal of solutions to those issues ③ Consideration of implementation (operation) system ④ Creation of implementation (operation) system (leasing) ⑤ concept design based on opinions of the shrine and operators ⑥ Product development (food and drink menu, selection of products for sale) ⑦ Consideration of revitalization of the shrine as a whole ⑧ Creation of a promotional video for the entire shrine ⑨ Consideration of CAFÉ promotion ⑩ Opening ceremony planning ⑪ Attracting various media ⑫ Implementing PDCA after opening ⑬ Create a new festival ⑭ Global promotional video for overseas By seeking supporters from our network (mainly local companies), we were able to create a system that can operate independently.

As a symbolic project to enhance the value of the Tobu Skytree Line, a commercial facility called "TOBU icourt" has opened in the Dokkyo University area. The facility is based on the concept of a place that offers "a comfortable life for everyone that satisfies the five senses of body and mind". Taking advantage of the characteristics of the area, which is home to educational and cultural facilities such as Dokkyo University and Matsubara Danchi Memorial Park, the facility has opened a total of 24 stores that meet the daily needs of diversifying lifestyles, including a major supermarket that offers food lifestyle suggestions. In addition, the facility will play a role as a base for promoting urban development that enhances the appeal of the area while further collaborating with the local government, residents, universities, and other local parties. It aims to continue to liven up the area through new connections born from exchanges through events with the facility, such as holding events in the adjacent park. We were in charge of the development planning, leasing, concept design /design supervision, facility naming, and logo development for this facility.

Tochigi Health Check Plaza is a medical facility that relocated and opened on January 15, 2024 for health checkups and medical examinations. In today's world, where people are expected to live to 100 years old, health management through regular health checkups and medical examinations is more important than ever. In order to realize the wishes of many patients that their annual medical examination day be a "rich and special day," we have created a space full of hospitality, from architecture to interior and furniture concept design. In order to respond to customer requests and a wide range of concept design areas, we teamed up with NAU (now the Architectural Production Department), which specializes in total concept design on an urban planning and architectural scale, and an interior concept design team that specializes in the hospitality market, such as hotels. By utilizing each other's expertise and concept design everything from the architectural scale to the human scale, we were able to ease the psychological anxiety of patients and create a space where they can spend their time comfortably and comfortably. With a smart appearance symbolizing a cutting-edge medical facility and a space filled with elegant colors, we aimed to create a facility that would take root in the local community and be beloved as a symbol of the town.

A new area connecting "Asakusa" and "Tokyo Skytree Town®" has been born. "Tokyo Mizumachi®" is a commercial complex under elevated railway tracks created in collaboration between Tobu Railway Co., Ltd. and Sumida Ward. Based on the concept of "Live to Trip - people, regions, and cultures come and go, spend your time as if you were traveling, and travel as if you lived there", we have developed a road-based project that includes supporting players who are rooted in East Tokyo and players who want to have a base in East Tokyo. By developing a town called "Tokyo Mizumachi®" as a collection of small individualities centered on players, it will be linked with Asakusa and Tokyo Sky Tree, and will be a fusion of [community-based x tourism leisure consumption] as a tourist spot in this area. We aimed for

At the beginning of the planning, Akikusa Gakuen approached us to ask about seismic retrofitting of the gymnasium. In conjunction with the seismic retrofitting and the renewal of the gymnasium facade and interiors, the corridor connecting the school building and the gymnasium was requested to be "a bright and clean corridor, not a humid and dark one. We wanted to create a space that the school can leave to future generations." This led to concept design of the corridor space expressing the identity of Akikusa Gakuen. The most important thing in this plan was to create a "space that people will continue to love." Therefore, this time, we created the origin of concept design together with the students in a workshop, and worked on a "progressive concept design" that would create attachment and be passed down. We asked the students to bring in photos that expressed "Akikusa-ness," and extracted the feelings they had put into words in the form of "#〇〇," sublimated them into concept design, and decorated the corridor. By having the students digest concept design as if it were their own and spread it to those around them, we hoped that the "Akikusa-ness" would be passed down from generation to generation and that people would continue to interact with the space with affection.

Following on from the 15th anniversary renovation in 2013, for which we were in charge of planning and design supervision, we were involved in the 20th anniversary renovation from the planning stage. After several renovations, the hotel was opened in 2019 as a milestone project that marked the completion of the entire renovation. The welcome space on the first floor and the restaurant floor on the fifth floor were completely renovated, the signs within the building were renewed, and new digital signage was installed. The renovation was based on the concept for the 15th anniversary, "Romanticship Umihotaru," and unlike the fourth floor, which had all openings facing the sea, the image of the space was created with only inward-facing openings and special decorations.

This is a renovation project for guest rooms, a bar, and a façade of a ryokan located in the western part of the Izu Peninsula in Shizuoka Prefecture. It has been reopened as "Atara Night Nishiizu", which is derived from the Manyoshu poem "A wonderful night that is regrettable to end". In terms of guest rooms, we have five suites and one concept room for groups and families. On the first floor, we were in charge of the renovation of the bar, the design of the façade, and the live kitchen.

This is a renovation project of the hotel "TheMana Village" located at the tip of Ashizuri Cape in Kochi Prefecture. Starting in 2020, the former Ashizuri Pacific Hotel will be reborn as a new “TheMana Village”. In the 2022 project, 5 new types of guest rooms and the Italian restaurant "Assurrissimo" in the facility have been expanded. Some of the new guest rooms are twin-type rooms with a large space of 96 square meters, equipped with a private sauna, water bath, open-air bath, and a special room with a fireplace in the room. Aiming to be one of the best resort hotels in Asia, this renovation project aims to provide a special accommodation experience. , is an ongoing project leading to the next renovation.

This project is being carried out by ARTH Group Co., Ltd. (Tosashimizu Resort LLC), a company involved in accommodation businesses and regional revitalization nationwide. The project aims to revitalize the entire city of Tosashimizu by revitalizing the long-established inn "Ashizuri Pacific Hotel Hanatsubaki," which has been loved for many years on Cape Ashizuri in Kochi Prefecture, as one of Asia's leading resort facilities for long-term stays, "The Mana Village." The facility is located in the natural beauty of Ashizuri-Uwakai National Park. Although it offers a spectacular view, the hotel's old interiors remains as it was, as if time had stopped since the Showa era. Initially, the plan was to set up a small cafe area, but as the meetings continued, ARTH's vision of wanting to liven up not only the hotel but also the entire city of Kochi and Tosashimizu expanded. The project has been transformed into a complex that includes an Italian restaurant, providing a luxurious space where you can experience the nature of Ashizuri. We have been involved from the concept stage of planning and concept design the facility to improve its appeal, and have been in charge of producing the space for the facade, lobby common areas, guest rooms, and restaurant, which will be the face of the hotel. (design supervision for guest rooms and Italian restaurant) As ARTH's creative partner, we are involved in producing spaces that lead to the creation and revitalization of attractive urban areas, including ``LOQUAT Nishiizu'' (renovating an old Japanese house into an auberge), which we took on in 2021.

To commemorate the 10th anniversary of the Nagoya Anpanman Children's Museum & Park, which opened in 2010, we will be in charge of the expansion of the "Takashi Yanase Theater" and the renovation of the "Big Tree and Forest of Play" as a power-up measure that will be responsible for the next 10 years. Thank you. Among the Anpanman Children's Museums in Japan, this facility is particularly focused on character shows and greetings, and will be a project of a dedicated theater where full-scale shows can be held and a plaza where parents and children can participate in play and events. Based on the concept of "Takashi Yanase Theater" and "Anpanman and his friends came when we were playing in the children's room," we created a warm wooden space and used building blocks, which are familiar toys for young children, as a motif. The building blocks, both inside and outside of the building, are integrated with the building framework so that the overall effect is large. In addition, by constructing the interior of the building with the vehicles, mechanics, and bread factory that appear in the anime, we have created a production that creates conversations between parents and children even during intermissions. Based on the concept of “a forest of big trees and play” and “the open space where Anpanman and his friends used to play until a little while ago”, a symbolic tree is arranged in the center, and it is a free space where parents and children can play around it and staff can hold events. increase. The ceiling surface is illuminated with blue skies, rainbows, and sunsets so that you can enjoy a day in the forest. Fixed playground equipment such as tunnels, slides, and peepholes are arranged to surround them, creating a space where parents and children can discover play in the forest.

This is Japan's first permanent museum specializing in infectious diseases. With the theme of "connecting the past and present of infectious diseases to the future," this facility conveys the knowledge and experience humans have built up from the past to the present, as well as steps toward the future. The COVID-19 pandemic has brought back memories of the struggle between humans and infectious diseases, and it is expected that infectious diseases will continue to pose a threat to us in the future. In this context, the Hideyo Noguchi Memorial Museum of Infectious Diseases is planned as a place where people can learn to "act correctly based on correct knowledge" regarding infectious diseases. The museum, which is a separate building from the Hideyo Noguchi Memorial Hall, was renovated and made use of the track record of the Hideyo Noguchi Memorial Foundation and the high level of expertise of the supervisors to differentiate it from the memorial hall. It consists of two displays rooms, and our company was involved in everything from architectural renovation to displays design and construction, as well as signage, content, and leaflet concept design.
