ISO/IEC 27001 data centers in Japan

Facilities in Japan that publish ISO 27001 certification. The baseline information-security certification most enterprise procurement teams require before a facility can host regulated workloads. It certifies the operator runs a documented information security management system, audited annually.

27 of the 133 facilities we track in Japan publish ISO 27001 — 7 operators, 149 MW of published IT capacity, 27 operational. Cities: Tokyo (Inzai), Tokyo, Osaka, Osaka (Chuo-ku), Tokyo (Tama), Osaka (Nishi-ku), Osaka (Minoh), Matsue, Shimane, Kobe (Kita-ku), Yokohama.

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.
