The blend of Japan's advanced digital capabilities with its exposure to natural disasters has made Disaster Recovery as a Service, or DRaaS, one of the most crucial technology initiatives that companies in Japan can pursue. Given that Japan is among the world's most earthquake-prone countries, it is constantly faced with an imminent risk of experiencing catastrophic events such as earthquakes, tsunamis, volcanic eruptions, and typhoons, all of which have the potential to cause extensive damage to infrastructure. In addition, Japan's businesses have been aware of the necessity to implement contingency plans for decades, but migrating from on-site failover to DRaaS will be instrumental in ensuring a seamless restoration process through automation and rapid system recovery, as opposed to the lengthy and potentially ineffective approach of setting up a redundant physical data centre. The stringent regulatory environment and high level of uncertainty in which Japanese businesses operate make choosing the right DRaaS partner a pivotal component of their organisational resiliency strategy.

Why Choosing the Right DRaaS Provider Matters in Japan?

The market of DRaaS in Japan includes global hyperscaler providers with regional presences in Japan, Japanese-based IT services companies, as well as dedicated DR providers. This is what every Japanese company needs to consider before picking a vendor:

• RTO/RPO commitment in line with Japanese regulations – Ensure that RTO and RPO commitments satisfy the high business continuity requirements of Japan's FSA, METI, and industry-specific regulatory bodies, and that these guarantees are legally binding.
• Survival of disasters and geographic isolation of data centers – Given the high risk of earthquakes in Japan, geographic isolation of primary data center and disaster recovery environment becomes a must-have requirement. Make sure that geographic isolation of your provider’s data centers means their physical separation from the perspective of seismic activity.
• APPI conformity and data sovereignty in Japan – The Act on the Protection of Personal Information regulates data handling in Japan. Check that all copies of data will reside only in Japan or APPI adequate territories.
• Language skills and local presence – In the case of a disaster, your provider will need to provide support immediately. Only local staff with language skills in Japanese will be able to provide it effectively.

Most Common Uses of DRaaS in Japan

Here are the most common categories of DRaaS and their ideal usage:

Consumer Trends: How Organisations Choose DRaaS Providers in Japan

• Earthquake and disaster recovery as the key adoption motivation – Natural disasters and earthquakes in Japan are a significant driver of DRaaS adoption – each large-scale earthquake leads to new investments into cloud-based continuity services.
• Regulatory obligations through FSA and other regulators – In Japan, the Financial Services Agency and relevant regulators require certain financial companies, insurers, and infrastructure businesses to have mandatory data recovery capabilities in place – which makes DRaaS a must-have for those organisations.
• Love for local players – A significant portion of Japanese businesses prefers local Japanese providers and hyperscalers' local regions when it comes to DRaaS – for the purposes of better data sovereignty and low latency, and also because of high trust in locally operating cloud services.
• Ransomware threat growth – The growing sophistication of ransomware attacks in Japan increases the number of businesses opting for more resilient forms of DRaaS that include immutable backups, dedicated isolated recovery environment, and guaranteed restoration to a clean state.
• Migration from legacy secondary data centres to cloud DRaaS – Japanese businesses are increasingly shutting down costly secondary data centres and are looking to adopt DRaaS as their primary disaster recovery solution.
