WE ARE NIKKEN

Founded over 125 years ago, Nikken Sekkei has evolved alongside Japan's modernization. Our design processes are shaped by the unique conditions of Japan, including limited land area, frequent natural disasters, and seasonal climate variations. Today, we also address climate change and societal issues such as an aging population, declining birthrate, and densely populated urban areas.
Our experience in addressing these issues has led us to pursue eco-conscious designs and advanced technologies for a sustainable future. Drawing from our global project experience, our diverse team of experts collaborates to provide optimized solutions tailored to each client. We build trust through deep knowledge of local culture and regulations.
Our mission is to give shape to our clients' visions and make meaningful contributions to society. For every new challenge, we apply our professional expertise and innovative thinking to create sustainable urban environments for future generations.

We are a collective of architects,
designers and experts working across multiple disciplines.

  • MISSION 1
    To achieve a better urban environment supporting the well-being of people through design
  • MISSION 2

OUR EXPERTISE

  • Architectural Design

    We aim to provide a total holistic multi-disciplinary

    Structural design is the key to safety in the creation of any building. We have constantly realized state-of-the-art structural design by
    developing and implementing
    cutting-edge technologies.

  • MEP Engineering

    Having MEP engineers
    in-house also promotes sustainability by giving us more control over life-cycle costing (LCC), an increasingly critical consideration for any architectural project.

    & BIM

    We are constantly working on providing the best service framework in the ICT age in order to cope with the increasingly complex
    large-scale buildings and intricate developments.

  • Urban Design

    in-house resources of planners, urban designers, architects, engineers and landscape
    specialists to provide
    integrated solutions focused on environmental and economic sustainability, functionality and visionary appeal.

  • Civil Engineering

    We have an extensive track record and experience in planning and designing urban infrastructure facilities.

  • Landscape Design

    Aesthetically pleasing outdoor spaces - public and private-serve to visually enhance the immediate surroundings and improve quality of life in the community.

  • Sustainability /
    Resilience

    Sustainability increases environmental resilience and is also important to protect people from risks such as natural disasters.

  • Management

    We ensure smooth project progression through services such as corporate real estate consulting, large-scale development management, technical consulting, project management, and construction management for design-build delivery.

#03 From sustainable to regenerative

The “Regenerative Tree” prototype, announced by Nikken Sekkei in May 2024, represents a pioneering approach to next-generation skyscrapers, introducing a range of workplace design innovations aimed to adapt to diverse work styles and reduce whole life carbon (WLC) emissions. Featuring an efficient steel-wood hybrid structure, a transport system using express elevators and escalators, diverse shared spaces, and MEP design inspired by biomimicry, this prototype is designed for Tokyo, but adaptable worldwide. We are actively collaborating with clients to implement this concept.

Key Design Features
  • Efficient steel-wood hybrid structure
  • Transport system using express elevators and escalators
  • Diverse shared spaces
  • MEP design inspired by biomimicry

Osaka, Japan - 1904

HERITAGE;
SINCE 1900

Founded in 1900, 26 professionals embarked on a journey. This was a time when Japan was rapidly pressing forward with modernization. Nikken Sekkei also was beginning to acquire the architectural styles and techniques of the west. This "pursuit of technology" went on to become an embedded basic principle in the firm.
The environmentally conscious design ethos evident in its very first project, incorporating natural day lighting and long building life, endures to this day.

SELECTED WORKS

Nikken Sekkei has over 125 years of history.
Still, we are constantly striving to create new value
to meet new demands.
