Denso · Kariya, Japan

Starting in 2019, Denso rebuilt about 72,000 m² of offices at its Kariya head office for some 18,000 people in 120 departments — two or three departments every weekend, while everyone kept working.

The head office Denso has occupied since it was founded in 1949, the benefits in Japan, and every step from Toyota's electrical-parts workshop to today's campus — then the business. Every number from Denso's own website, careers site, newsroom and 75-year history, plus the designers' project pages.

THE OFFICE REFORM · KARIYA HEAD OFFICE · 2019–

72,000 m² of offices rebuilt around “three Cs”

In 2019 Denso set out to change how its head-office staff work, under the concepts Connectivity, Crossover and Collaboration. Over three years about 72,000 m² of offices in six buildings were renovated for some 18,000 people in 120 departments, with free-address seating, mobile PCs, chat and web meetings, less paper and standard furniture. Every department was surveyed and interviewed two or three times and given an “operation”, “function” or “innovation” type of layout; staff chose their own furniture and carpet colours from a Denso-only catalogue after testing them in a model room. Work went on department by department, two or three every weekend, while people stayed in the buildings. When the pandemic arrived near the end of the project, almost everyone already had a mobile PC and could switch to working from home.

Map: how the headquarters moved

Denso has never moved its head office: the electrical-equipment plant Toyota gathered at Kariya-kita in 1948 became Nippondenso in 1949 and is still the head office at 1-1 Showa-cho. In Tokyo it now has an office in Shimbashi and an R&D site at Haneda.

What Denso does

Denso was born in 1949 when Toyota's electrical-components factory in Kariya became an independent company, so that it could sell to other carmakers too. Today it makes electrification, powertrain, electronics, semiconductor and safety parts for cars, and says it is the world's No. 2 supplier of mobility products.

Business groups include Mobility Electronics, Powertrain Systems, Semiconductors and System Control Components, plus newer fields such as food value chain, factory automation and hydrogen.
