About

Since 1975 Interoffice has been bringing the world’s best furniture and design to Japan.


We pride ourselves on not simply selling products, but also communicating the ideas, and the very meaning of work, behind those products, through a marriage of Interoffice expertise, and premium brands such as USM and Vitra.


Globalization and the dissemination of digital technologies mean that people now understand far more deeply the value of having spaces that allow them to work creatively.


We are confident that office and living spaces in Japan—while incorporating outside influences—will continue to evolve in their own unique ways.


Here at Interoffice we ourselves are evolving, from a company that showcases western working styles, into one that partners with clients to craft new, forward-focused ways of working and living.


Our mission, to take design to the next generation, encompasses both respect for the past, and responsibility toward the future.


And in accordance with our vision of a society that rejects throwaway design, we look forward to working alongside you to build a future of vibrant, enduring spaces and design options, and in turn, a legacy of sustainability across generations.

Mission
Taking design to the next generation

For 50 years now Interoffice has been bringing the world’s finest furniture and design to Japan, and generating new value in our clients’ spaces.


Our mission is to take the culture and philosophies behind this design into the future, and convey the strength and significance of design to the widest possible audience.

Vision
Building a society that rejects throwaway design

Interoffice has set its sights on taking the value of timeless, cherished design into the next generation.


This means helping to build a society that protects and passes on the value of durable design, rather than design for short-term consumption, by making recycling a prerequisite for all our projects.

Value
Pursuing and proposing possibilities

Making reality a society that rejects throwaway design, requires a commitment to exploring better possibilities, beyond limitations and the bounds of received wisdom.


Each member of our team possesses the high-level design literacy needed to identify hidden issues and subtle differences, offer clients and the wider community new ideas from unique perspectives, and guide those ideas to realization.

Good Design IS Good People

Strategy for genuine design

Throughout our long history of importing top-quality office furniture for the Japanese market,our constant desire has been to seek out and acquire the best available examples of what we consider “genuine design.” That’s why we import so many Good Design Special Award-winning office furniture pieces. Additionally,
we actively sponsor design exhibitions and hold numerous competitions for young designers.
It is through these types of activities that we discover top-quality designs,
help establish new and exciting designers, and nurture strong design sense throughout society.

Environmental considerations

We believe that environmental friendliness is a part of design and quality.
Interoffice only selects furniture that passes stringent European and American environmental regulations. As opposed to the Japanese Act on Promoting Green Purchasing, which focuses on promoting use of recycled plastic, these regulations require sustainability and long-term reduction of environmental impact.

Information management and protecting your privacy

Interoffice sees the workplace as an embodiment of the management strategy itself. As such, we take utmost care when handling important information such as name lists and office floor plans.
