Komatsu

The Japanese construction- and mining-equipment maker founded in 1921 in Komatsu, Ishikawa (from memory, verify), which made "Maru-C" — encircle Caterpillar — its internal battle cry in the 1960s (from memory, verify), won the Deming Prize for quality (1964, from memory, verify), took share from Caterpillar in the early-1980s strong-dollar years by selling similar machines for up to ~30% less in markets such as Latin America and Africa (Time, via the Caterpillar C03 file), and then changed the industry twice with connected equipment: KOMTRAX telematics (2001) and FrontRunner autonomous haulage, commercial from 2008, which reached its 1,000th ultra-class driverless haul truck in Apr 2026 (company). It bought Milwaukee's Joy Global in Apr 2017 for ~$3.7bn including debt (Komatsu America release, via trade press), making the US its largest mining-equipment base. In the fiscal year to Mar 2026 it sold ¥4,132.8bn (+0.7%) with an operating margin of 13.7% (−2.3 points) and net income of ¥376.4bn (−14.4%), squeezed by a stronger yen and US tariffs (company release, 28 Apr 2026). Its manufacturing story turns on process quality as the challenger's tool, connected machines as the installed-base business, and a global footprint that now has to answer US tariffs.

8 strategic moves analysed

Each one gets a full strategy file in the companion: context, the decision, the financing, what happened, and the lesson.

1921
Founding in Ishikawa
Founding (spin-out of a mine's ironworks into a machinery company)
1961
