System Architect Certification Guide
System Architect Certification Guide
Certification Overview
The System Architect (システムアーキテクト) is a national certification in Japan that evaluates advanced expertise in information system planning, requirements definition, and design. It is an advanced certification that confirms knowledge required for designing large-scale systems and architectures.
This certification covers system design specialization techniques. It evaluates advanced knowledge across system design including requirements analysis, system architecture design, system structure design, and interface design. The goal is to develop experts capable of efficiently designing large-scale systems.

Preparation Methods
Step 1: Basic Learning (2-3 months)
Learn basic concepts of system design. Study software engineering, requirements analysis, and system design principles using textbooks.
Step 2: Learn Design Patterns (3-4 months)
Learn architecture patterns and design patterns. Understand patterns through actual system design cases.
Step 3: Learn Practical Knowledge (3-4 months)
Learn practical knowledge of system design. Participating in actual system design projects or studying cases is helpful.
Step 4: Past Exam Practice (3-4 months)
Solve past exam questions from the last 5 years. The afternoon questions are essay-type, so practice explaining problem-solving processes logically.
Step 5: Mock Exams (1-2 months)
Take multiple mock exams during the 1-2 months before the test. Practice time management and focus on improving weak areas.
Pass Rates for the Past 5 Years
| Year | Examinees | Passed | Pass Rate |
|---|---|---|---|
| 2024 | 10,234 | 1,456 | 14.2% |
| 2023 | 11,782 | 1,745 | 14.8% |
| 2022 | 10,123 | 1,478 | 14.6% |
| 2021 | 9,891 | 1,334 | 13.5% |
| 2020 | 8,456 | 1,134 | 13.4% |
The average pass rate is approximately 14.2%, which is relatively low even among advanced certifications. Having practical system design experience makes learning easier.
Practical Tips
Practical Experience Essential: If you have experience designing systems, you can learn more easily by understanding based on that experience.
Learn Design Patterns: Study architecture patterns and design patterns in depth. Researching patterns applied in actual systems is also helpful.
Study System Cases: Researching actual large-scale system design cases helps with the exam. Find and analyze published architectures.
Essay Practice: As afternoon questions are essay-type, practicing logical explanation of problem-solving processes is important.
Stay Updated on Technology Trends: As system design technologies continue to evolve, staying informed about the latest architecture patterns and technology trends is also important.
