SHOKUTAKU

Located near Toritsu-daigaku Station in Meguro, Tokyo, this restaurant offers a selection of homestyle cooking paired with natural wine. While preserving the raw character of the former tenant’s interior, the renovation introduces bespoke counters tailored to the respective roles of the husband-and-wife owners. The kitchen-side counter repurposes the existing structure as its base, whereas the bar counter was newly fabricated from the ground up; both are unified with light blue terrazzo tile tops. A yellow glass shelf is positioned directly across from the entrance, serving as a vibrant focal point to welcome guests. By accenting the original textures and vintage furniture with light blue terrazzo and custom yellow elements, the design captures the cheerful and warm dining experience hosted by the couple.

EPOCH

Set within a lush, green environment, this office relocation project leverages expansive windows to integrate natural light into the workspace. The design facilitates a flexible environment where staff can choose their setting based on the day’s tasks or their personal mindset. While the main work areas utilize a beige-based palette to harmonize with existing furniture and foster a sense of calm, the meeting and open spaces transition to gray tones, creating a focused atmosphere with a productive sense of clarity. The strategic placement of the company’s art collection further enhances the interior, adding visual depth and clear sightlines throughout. By meticulously balancing material textures and lighting, the office achieves a cohesive, natural environment that feels both professional and inviting.

aretosore

Located along a shopping street in Sanjō, Niigata, this small baked-goods shop occupies a compact two-story building with a total floor area of just 21.8 m². On the ground floor, baked treats are displayed alongside an eight-seat counter where the shop can also operate as a café. Upstairs, a fully equipped kitchen is arranged to produce around 20 varieties of baked goods each day on a rotating menu. Given the shop’s modest scale, the design focuses on the sense of proximity between the owner, customers, and the pastries themselves. Circulation, fixture dimensions, and sightlines were refined down to the millimeter to create an experience that feels both intimate and comfortable. To highlight the character of the shop’s baked goods—infused with “this and that (aretosore),” as suggested by its name—the interior palette was intentionally kept minimal, forming a calm and cohesive backdrop. With a restrained material composition, the space allows the pastries to take center stage. The stairwell, finished in a silver tone that appears to float, draws daylight down to the shop below, creating a sense of openness within its compact interior. At the top of the stairs, a small window offers a glimpse into the kitchen, serving as a subtle device that sparks curiosity for everyone who visits.

TUMO Gunma

This facility, located within a convention center in Takasaki, Gunma, is Asia’s first educational center dedicated to developing digital creativity. It introduces the internationally acclaimed program from TUMO, a digital education institute based in Armenia, offering junior and senior high school students the opportunity to learn cutting-edge digital skills free of charge. The program combines self-learning—where students move freely with their laptops to study anywhere within the facility—with workshops held in four dedicated workshop rooms.
Following TUMO’s global design guidelines, the layout and material palette were developed while integrating a distinctly Japanese sensibility through the use of Japan Blue, a traditional indigo dye color, as the key tone. Together with prefectural officials, we explored how to create a space that encourages students to come and learn independently, even within a self-directed environment.
In the main hall, which was formerly a 500-seat conference room, a new 70 cm-high floor structure modeled after natural terrain was introduced. Multiple learning spots were created to allow students to study in any posture they choose, breaking away from the conventional classroom layout of aligned desks and chairs. The change in height and body posture helps refresh the mind and sustain engagement in learning. To address the absence of natural light, the lighting system is programmed to change color temperature throughout the day, simulating natural daylight and helping maintain students’ circadian rhythms.
In the panoramic area overlooking Gunma’s mountains, eleven movable desks called TUMOBILE—locally fabricated based on 3D data—were installed, enabling flexible learning styles beneath a softly illuminated membrane ceiling. In the adjacent gallery area, a 21-meter-wide LED screen displays videos created by the students and streams live footage of the main learning space behind its enclosed walls.
This project was realized as part of Gunma Prefecture’s initiative to establish tsukurun, a creative hub for nurturing talent equipped with digital skills and the ability to generate new value. With the introduction of the TUMO program, the prefecture aims to expand and deepen its creative education efforts. We hope this new learning environment will broaden children’s future possibilities and cultivate individuals who can apply what they learn here to the world beyond.

House in Gosen

This project is a renovation of a traditional two-story wooden house—approximately 230 square meters in size—located in Gosen City, Niigata Prefecture. Originally home to three generations, the house is now occupied by the client and their son. The goal was to create a more compact living environment suited to a two-person household. The renovation focused on approximately half of the ground floor—an area large enough to accommodate daily life—and was enclosed with insulation for improved energy efficiency. On the opposite side of the central hallway lie a guest room and Buddhist altar room with a spacious engawa. It is a calm and pleasant space, where views of the garden can be enjoyed through open shoji screens and sliding doors in spring and autumn. To allow the house to be used more flexibly across the seasons, large sliding partitions were installed to separate the renovated and unrenovated areas. Finishes such as the floorboards, tiles, and other materials were carefully selected to complement the existing decorative elements—such as feature windows, coffered ceilings, and amber-toned floorboards—creating a balance of contrast and harmony so that the renovated area feels integrated with the overall structure. Amid the growing number of similar houses affected by population decline and an aging society in rural Japan, this project may offer one possible approach to reimagining traditional homes for contemporary life.

NIGIRO

Located within LALA PARK SUEHIRO, a newly developed multi-purpose complex in central Takasaki, this rice ball (onigiri) shop was designed around the concept of made-to-order preparation, with each onigiri freshly hand-shaped upon request. An open kitchen layout allows all operations—from cooking and serving to clearing and payment—to be carried out seamlessly within the counter area. The height and placement of each element were carefully calibrated to ensure smooth workflow and efficiency. To maintain a clean, welcoming atmosphere, kitchen equipment is kept out of view from the eat-in area, with custom fixtures such as a display cover and cashier counter thoughtfully integrated into the space. The interior combines the casual feel of a coffee stand with a gentle touch of traditional Japanese sensibilities, using warm materials and ceiling finishes to create a harmonious, inviting environment.

CHERRY

This is an office relocation project for CHERRY Inc., a company engaged in addressing social issues through a wide range of creative planning and production, primarily in the advertising field. In the entrance hall, a custom-made counter made of Bealstone infused with the company’s signature logo color glass serves as a multifunctional space—for meetings, workshops, and as a community hub for both internal and external creatives. On the second floor, custom-built desks with integrated partitions were installed to help each individual stay focused. The overall layout encourages circulation, creating a compact yet well-balanced sense of distance between individuals and teams. The space is also designed to display CHERRY’s diverse collection of artworks—accumulated since the company’s founding—throughout the office.

House in Hikarigaoka

This project is a renovation of an apartment unit in a verdant housing complex in Hikarigaoka, Tokyo. Designed for a family of three, the home incorporates a variety of functional zones, including a study for work and a small bookshelf nook in the living room for casual tasks. Lauan plywood is used as the finishing material throughout the space. In the living room, subtle variations—like shifting the wood grain orientation and adjusting the tone of the oil finish—lend each area its own character while preserving a sense of overall harmony. By applying the same material in different ways, the design creates a rich and varied living environment that reflects the nuances of everyday life.

lalu

This Italian restaurant is located along the moat of Takasaki Castle Ruins in the center of Takasaki City. The large glass windows on the façade offer a view of the moat, while the interior of the restaurant can be seen from the outside. The interior design is characterized by the contrast between the rough impression of the existing walls and the furniture made of lauan plywood. The gap between the kitchen’s hanging shelves and the counter is kept as small as possible to create a moderate distance between the customer seats and the kitchen, creating a relaxed atmosphere.

KATARIBA

This is an office relocation project for Katariba, a certified nonprofit organization committed to creating a society where all young people—regardless of their upbringing—can nurture the creativity and motivation to shape their own futures. In a post-pandemic work environment, with around 80% of staff working remotely, the project was developed in close collaboration with the client to explore the purpose and value of gathering in a shared space. In response to the client’s desire to “create spaces that foster dialogue,” the design centers on the concept of the engawa—a traditional Japanese architectural element that blurs the boundary between inside and outside. Engawa-like features were incorporated on each floor to encourage casual, spontaneous interaction, such as placing benches face-to-face or installing high counters along circulation paths. The overall space is unified in soft gray tones, accented by “Katariba Green,” the organization’s signature color, to create a warm and approachable atmosphere. Signage was designed by YOHAK DESIGN STUDIO, and sound design was handled by Sound Couture Inc., resulting in a spatial experience that engages both sight and sound. The conversations and connections that emerge here will continue to deepen the value of the space over time.

Khaki

This is an office relocation project for Khaki Co., Ltd., a VFX direction and design company. In addition to an office and meeting room, a preview room was required to check the produced images. The conference room and preview room, which frequently receive visitors from the outside, were placed in an entrance area separated from the office to ensure security of the office. The office area is large enough to accommodate future increases in staff, and includes a lounge for employees. The lounge will be used not only for breaks but also for dinner parties, so we designed sofas and side tables that can be reconfigured to suit the needs of the client.
