Widening into civil, HVAC and nuclear work, and renaming to Kandenko (1984)
You can change the name; the purchase orders stay the same
A change of name moves nobody’s terms of trade. On the day in September 1984 when the words “Kanto Electric Works” disappeared, the sites and the purchase orders were exactly what they had been the day before. If the rename is still worth reading as a business decision, it is because the company took the occasion to settle again how it would describe its own business. “Electrical works” was also the distributor’s name for the job it placed. Removing that phrase from the corporate name overlaps with a declaration that customers would be sought outside the party placing the orders.
The distance from declaration to reality was long. Fourteen years later, in 1998, Kandenko was still appearing in print as the most utility-dependent contractor of its peer group, setting up a renovation-work unit and moving its maintenance departments into prefecture-by-prefecture subsidiaries. Reaching the mix of the year to March 2025 — ¥350.6 billion of indoor wiring and building systems against ¥126.7 billion of distribution-line work — took a further quarter of a century. A company’s name can be changed first; the composition of its order book moves only once a year.
