Kyocera, Kobe Steel and ~16 other Japanese manufacturers will share an AI built by Arum, the 40 person Kanazawa software firm, that turns blueprints into machine tool instructions, starting in October.
Japan's Kyocera, Kobe Steel, Nidec Machine Tool and a Sojitz-affiliated company are joining roughly 16 other manufacturers to share a single AI for factory robots, with a four-year build-out starting in October, Kyodo reports.
The AI is built by Arum Inc, a 40-person software firm in Kanazawa founded in 2006. Its TTMC system takes a part blueprint and produces the cutting instructions a machine tool follows, per a Microsoft Asia feature and customer story. Microsoft's Japan unit is expected to participate as a partner, Kyodo reports.
The consortium plans to scale TTMC from small parts to medium and large parts used in construction machinery and semiconductor manufacturing equipment. Arum posted sales of about 7.4 billion yen (~$46 million) for the year ending June 2026, according to a Microsoft profile of CEO Takayuki Hirayama.
Three questions remain: whether a 40-person team can carry the load for majors, who owns the IP when 20 firms share one system, and how much control Microsoft Japan ends up with. The move sits inside a broader Japanese push. The government is targeting 370 trillion yen (~$2.5 trillion) in public and private investment across 17 sectors by fiscal 2040, Kyodo reports. SoftBank and NEC have separately formed a JV called Noetra for "real-world native AI" by 2030.
