Do we like Komatsu?

Makes construction and mining machinery, forklifts and industrial machines; based in Tokyo, Japan.

Our score: 6 out of 10. A big, established heavy-equipment maker with no major scandal in what we found. We'd back it modestly, though our evidence is thin and we found little on its environmental record.

Komatsu is a Japanese giant that builds bulldozers, diggers, mining trucks and forklifts. It's listed on the Tokyo stock exchange and has just celebrated its 100th year.

The top job sits with Takuya Imayoshi, President and CEO. A February 2026 board notice said he stays in post, that Taisuke Kusaba becomes a Representative Director from April 2026, and that Takeshi Horikoshi moves to adviser after the June 2026 shareholder meeting.

On the trouble side, we found only small stuff. California's air regulator CARB settled with Komatsu Forklift U.S.A. in 2022 for $18,500 over selling forklifts in California that weren't certified. Good Jobs First's tracker also lists a $20,000 EPA Clean Air Act penalty from 2003.

So it's a solid, low-drama industrial firm, but it sells machines that burn a lot of diesel and serve mining. We'd give it a cautious 6.
