Women in Architecture: Kazuyo Sejima

As part of our ongoing “Women in Architecture” series, we’re putting a spotlight on one of the world’s most cherished architects, Kazuyo Sejima. Throughout her breathtaking portfolio of work, Sejima has exhibited her enigmatic and refined point of view and became the second woman ever to receive the acclaimed Pritzker Architecture Prize. Today, we’re diving into Sejima’s notable life, work and achievements.

The Life and Career of Kazuyo Sejima

Sejima was born in Mito, Ibaraki, Japan in 1956. After discovering her passion for architecture and design at a young age, she began her studies at the Japan Women’s University, where she completed both an undergraduate degree and a graduate degree in architecture. Following her graduation in 1981, Sejima began apprenticing with Toyo Ito – a renowned Pritzker Award-winning architect also from Japan. 

After nearly seven years working with Ito, Sejima felt empowered to launch her architecture firm, Kazuyo Sejima & Associates, in 1987. Directly after opening, Sejima convinced her long-time confidant, whom she worked with under Ito, Ryue Nishizawa, to work with her at her firm. Nishizawa gladly joined Sejima, and nine years later, the pair founded a firm of their own, Sejima and Nishizawa and Associates (SANNA). And, thanks to Sejima and Nishizawa’s visionary designs, SANNA quickly became a nationally renowned firm after only a few years. 

Sejima’s designs are frequently recognized for their vibrant materials and colors, including various types of marble, glass and metals. She also often takes advantage of organic forms and aesthetics in her work, thoughtfully exploring each design as an instrument for human experience. Sejima’s appreciation for sheer glass in many other builds allows for an abundance of natural light, helping to create a more fluid transition between interior and exterior environments.

Throughout her career, Sejima has expressed the same concern for each of her projects: the functionality of the space’s social uses and their potential for adaptation. This philosophy explains why she doesn’t consider any of her builds finished until each of its inhabitants places pieces of their lives into the space through their various actions and interests. 

Notable Works and Achievements

Sejima translated her vision and architectural philosophy into her first project, Platform House I, in 1987. Sejima built the Platform House in a Japanese suburb and took inspiration from western designs, intermixing traditional Japanese values with European elements of architecture. With her first project, Seijam set out to create a living environment built with a platonic ideal of architecture – where it would function as provisional to the residents based on their actions and lifestyle. 

Throughout the house, Sejima experimented with large spaces, positioning the building’s central living area a half level below the kitchen and a half level above the sleeping floor below. Sejima also adopted her signature use of bright materials throughout the home, utilizing floor-to-ceiling windows in the home to illuminate its interior spaces and a gleaming, corrugated metal roof to signature the movement and human interaction that occurs below it. Following Platform House I,  Sejima designed companion projects: Platform House II and III.

Sejima extended her vision across the world, and in 2007 she, along with Nishizawa, designed the New Museum of Contemporary Art in New York City. Their design was chosen due to its adaptable atmospheres – mirroring the ever-changing nature of contemporary art. From the exterior, the building’s bold design consists of four white cubes that sit on top of one another, further symbolizing the dynamic energy of contemporary culture. After its completion, the building received praise, and Conde Nast Traveler named it one of the architectural New Seven Wonders of the World

Most recently, Sejima constructed a vibrant tribute to renowned Japanese artist Hokusai Katsushika through the Sumida Hokusai Museum in Tokyo, Japan. Sejima thoughtfully designed the building to blend in with its surrounding urban environment, making it more accessible to its visitors. Sticking to her trademark design elements, Sejima used reflective aluminum panels to cover the façade. The building’s exterior also features various slits on all sides, eliminating the notion of a “front” and “back”, and providing outdoor walkways connecting each first-floor area.

Alongside her extraordinary work, Sejima has also received numerous architecture and art awards as well as achievements:

  • Young Architect of the Year, Japan Institute of Architects, 1992
  • Prize of Architectural Institute of Japan, 1998, 2006
  • International Fellowship of the Royal Institute of British Architects, 2007
  • Pritzker Architecture Prize, 2010

Today, Sejima continues to fearlessly voice her unique architectural perspective, gifting the world with her ambitious designs. She currently teaches as a Visiting Professor at Tama Art University and Japan Women’s University. And, succeeding Zaha Hadid in 2015, she leads an architectural design studio at the University of Applied Arts Vienna.

Modernism and Japanese Architecture

In the same way our own practices at Optima are rooted in and inspired by Modernist design, so too is the work of other architects and designers across the decades, and across the world. One of the joys of our industry is seeing how design translates through the lenses of other cultures and countries, and Modernism and Japanese Architecture have a truly fascinating connection.

The History

The Modernist movement began in the early 20th century, pioneered by architects such as Walter Gropius, Mies van der Rohe and Le Corbusier. Le Corbusier, who traveled extensively during his lifetime, drew inspiration from traditional Japanese homes, sukiya-zukuri. Influenced by teahouses, sukiya-zukuri typically includes modest spaces designed with natural materials such as wooden columns and earthen-plaster. Pillars support the structure of the home, which allows for sliding screen walls to filter natural light into the rooms and blurs the barrier between outdoors and in. Le Corbusier used similar designs across his work, creating a connection between Japanese and Modernist architecture that only continued to grow.

In the 1930s, Japanese architects such as Junzo Sakakura and Kunio Maekawa collaborated with Le Corbusier, further fusing the two styles. Sakakura eventually rose to the chief of staff of Le Corbusier’s atelier in Paris, working on projects such as the 1932 Swiss Pavilion, which included sliding windows and open space for nature to flow in and out. The progress made from these collaborations impacted both Modernism and Japanese architecture — then and now.

Influences Today

Japanese influences are apparent across many executions of Modernist design. Intentional materials (whether they consist of wood, stone or metal), open floor plans and clean, minimalist spaces are present in both practices. Green space or gardens is also a huge similarity; and one we incorporate across all of our Optima projects. Through noticing and appreciating where these styles originate, we gain a greater knowledge and understanding of the world of architecture, and architecture throughout the world.
