ISO 14001 data centers in Japan
Facilities in Japan that publish ISO 14001 certification. Environmental management system. Increasingly requested in European tenders and by companies with public emissions targets.
22 of the 133 facilities we track in Japan publish ISO 14001 — 5 operators, 38 MW of published IT capacity, 22 operational. Cities: Tokyo, Osaka, Osaka (Chuo-ku), Osaka (Nishi-ku), Osaka (Minoh), Matsue, Shimane, Kobe (Kita-ku), Yokohama, Kanagawa.
For context, wholesale colocation in Japan is benchmarked at $280 per kW per month (CBRE, Global Data Center Trends 2026 (17 June 2026)), and commercial electricity at $0.185 per kWh — certification rarely changes the rack rate, but it narrows the shortlist.
