Cloud & DevOps Company in Tokyo

How much FISC-grade control the landing zone must enforce decides the figure: a scoped Landing Zone build for AWS ap-northeast-1 or Azure Japan East with FISC-aligned controls, Tokyo-Osaka DR, IaC, and CI/CD pipelines, a full enterprise platform with multi-account or multi-subscription topology, EKS or AKS clusters, observability, FinOps, and bilingual runbooks, or FISC Security Guidelines uplift for a banking-eligible workload. Scope drivers include the account or subscription topology, the number of clusters and environments, and the volume of FISC 11th-edition controls in evidence. We quote fixed-fee against deliverables in JPY with USD equivalents at the prevailing rate, with consumption tax handled under the Qualified Invoice System (Tekikaku Seikyusho hojin bango, effective October 2023).

Japan's APPI (Act on Protection of Personal Information) was significantly amended effective 1 April 2022, with the Personal Information Protection Commission (PPC) tightening cross-border transfer rules. Transfer to a country on the PPC adequacy list (currently the EEA and the UK) is permitted without additional consent. Transfer to any other jurisdiction requires either explicit consent disclosing the foreign jurisdiction's protection regime in the Japanese-language notice, or equivalent contractual safeguards documented under Article 28. We default Tokyo cloud builds to Japan-region primary in AWS ap-northeast-1, Azure Japan East, or GCP asia-northeast1, with cross-region DR in ap-northeast-3 (Osaka), Japan West, or asia-northeast2. Where a US-based managed service is genuinely unavoidable (some observability or analytics SaaS), we capture explicit consent in the Japanese-language privacy notice, document the contractual protections under Article 28, name every subprocessor and region in the DPA, and keep a transfer impact assessment template ready for procurement. The PPC accepts the package without forcing a second submission.

The Center for Financial Industry Information Systems (FISC) Security Guidelines are the de facto cyber and information security standard for Japanese financial institutions, currently in the 11th edition. They are not legally binding in themselves, but JFSA supervisory examinations reference FISC compliance as a baseline expectation, and banks, securities firms, and payment service providers treat FISC adherence as mandatory for market acceptance. The guidelines cover operational management, technical controls, physical security, system development controls, and audit requirements, with roughly 350 controls across the volume that map directly onto cloud platform decisions. Our FISC delivery for a cloud platform includes a controls-to-evidence mapping in the format FISC peer reviewers and JFSA examiners expect, AWS Control Tower, Azure Management Groups, or GCP Organisation policy that enforces the technical controls, Tokyo-Osaka active-passive topology that satisfies the FISC system continuity expectations, SOC and incident response that align to FISC operational management, and a board reporting cadence aligned to JFSA supervisory dialogue. We have benchmarked against the public disclosures of MUFG, SMBC, and Mizuho on cloud architecture and FISC alignment.

Yes. Sakura Internet (TYO 3778) operates the Ishikari data centre in Hokkaido as the largest domestically-owned cloud facility in Japan, and IIJ (TYO 3774) operates IIJ GIO with deep public-sector and FISC-regulated banking relationships. For workloads that cannot tolerate hyperscaler dependency under APPI or FISC expectations (selected government systems, some megabank critical workloads, defence-adjacent integrators, and PMDA-regulated medical platforms), the sovereign tier is the credible choice. We deploy Kubernetes (often Rancher or self-hosted upstream), Terraform-managed VPCs, and Japanese-language SRE runbooks on Sakura and IIJ. Multi-cloud topologies frequently pair Sakura or IIJ for sovereign workloads with AWS ap-northeast-1 or Azure Japan East for general scale and modern managed services. Sovereign deployment costs run higher than hyperscaler equivalents but materially lower than building bespoke private cloud, and the procurement story carries weight with Japanese government and FISC-regulated buyers.

Japan's MyNumber (kojin bango) is the 12-digit national identifier introduced in 2016 and gradually expanded into health insurance, driver licence, and bank account linkage through the MyNumber Card chip. The MyNumber Act treats MyNumbers as tokutei kojin joho (specially-categorised personal information) with stricter storage, access, audit, and retention rules than ordinary APPI personal data. We design MyNumber-handling cloud platforms with isolated encrypted stores (AWS KMS or Azure Key Vault with per-tenant CMKs, dedicated cryptographic boundaries), segregated access roles (only documented HR or finance personnel with statutory business need can read decrypted numbers), full audit logging on every read with retention aligned to the MyNumber Act, and DR architecture that pins MyNumber data inside Japanese regions only. The Digital Agency (digital.go.jp) and the PPC both publish detailed MyNumber handling guidelines and we map every cloud control to them. For platforms that do not strictly need raw MyNumbers, we tokenise upstream and forward only to freee, Money Forward, or government filing endpoints, so the cloud platform itself never persists the identifier.

Japanese enterprise expectations for operational resilience sit at the high end of the global market. JFSA pushed an operational resilience framework on regulated financial institutions post-pandemic. METI and IPA published manufacturing-cyber and OT-resilience guidelines after the 2022 Toyota-Kojima Industries ransomware incident halted production at fourteen Toyota domestic plants. Tokyo cloud platforms typically deploy active-passive across AWS ap-northeast-1 and ap-northeast-3, or active-active across Japan East and Japan West, with cross-region database replication (Aurora Global Database, Cosmos DB multi-region writes, Cloud SQL cross-region replicas) sized to RPO under 5 minutes and RTO under 30 minutes for critical workloads. We build chaos engineering programs using AWS Fault Injection Service, Azure Chaos Studio, or Gremlin, rehearse cross-region failover quarterly with Japanese-language playbooks, and document the resilience evidence pack in the bilingual format JFSA examiners and FISC peer reviewers consume directly. The Toyota-Kojima incident also reset supplier cyber expectations, and we cascade tier-1 supplier assurance into the cloud platform vendor register.

Yes. Most Tokyo enterprise cloud transformations involve a domestic system integrator (NTT Data, NTT Communications, Hitachi Systems, Fujitsu, NEC, ITOCHU Techno-Solutions, Nomura Research Institute, TIS) as the prime contractor for legacy migration, ERP transformation, and government-adjacent procurement. Codazz frequently engages as a specialist subcontractor or co-delivery partner for cloud-native engineering, Kubernetes platform builds, SRE uplift, FinOps, and DevOps tooling where the prime SI brings the relationship and the domain knowledge. We respect the keiretsu procurement structure (ringi-sho internal approval, kacho and bucho approval workflows, customer success in Japanese with QBRs on the Japanese fiscal year April-to-March), and we ship bilingual artefacts the prime SI can submit upstream without rework. Where a client engages Codazz directly without a prime SI, we deliver the same end-to-end and coordinate with downstream operations teams in Japanese.

METI and MIC jointly published the AI Guidelines for Business Operators in April 2024, consolidating earlier METI AI Governance Guidelines and MIC Social Principles into a unified framework that Japanese enterprises now treat as the operational baseline for AI deployment. The guidelines cover governance (board-level AI oversight, risk classification, human-in-the-loop expectations for high-impact applications), data handling (APPI compliance, training data quality, bias mitigation), transparency (documented model behaviour, interpretability for high-stakes use cases), and incident response. For cloud and DevOps engagements that host AI workloads we deliver a Japan AI Guidelines mapping against the platform, training data residency inside Japanese regions where APPI personal data is in scope, MLOps pipelines with reproducible training runs and lineage capture (MLflow, Weights and Biases, SageMaker), evaluation harnesses that gate production deployment, and incident response runbooks that handle AI-specific failure modes. The Digital Agency has also published AI procurement guidelines for the public sector that align closely with the METI-MIC framework.
