ISO 27001 certification in Tokyo at a glance
Shinagawa, Shibuya, Shinjuku and Ikebukuro are all named areas of Tokyo's special zone for Asian headquarters, and a regional headquarters there rarely holds only its own data. It holds customer records, group financials, source code and contracts that move between Tokyo and offices abroad. ISO 27001 is the standard that shows how such information is protected. It asks for a defined scope, a risk assessment with a treatment plan, a statement of applicability against the Annex A controls, then internal audit and management review. Sterling's Tokyo office works through each step with your people, holds the risk register in Effivity and readies you for an accredited certification body's assessment.

ISO 27001 in Tokyo: questions clients ask
Why do Tokyo headquarters offices pursue ISO 27001?
Group parents and customers send security questionnaires that grow longer each year. A certified system answers most of them with a single scope statement and evidence. It also shows Tokyo management that risks are owned and reviewed, rather than left to a few engineers. The scope should match the business that customers actually rely on.
Can a Tokyo startup scope ISO 27001 narrowly?
Yes, if the scope is accurate. A startup can certify the product, team and cloud environment that handle customer data and leave unrelated activity out. Customers read the scope statement closely, so it should describe the service they rely on. A narrow, accurate scope is easier to maintain.
