The rising pass rates can be attributed to improved study materials and better preparation by examinees. However, this is by no means an easy exam. Thorough preparation is essential.
Effective Study Methods
Based on 20 years of experience in construction and the study patterns of many successful examinees, here are 5 effective study methods.
1. Repeat Past Questions (At Least 3 Rounds)
What successful examinees have in common is that they go through the same question bank at least 3 times.
- Round 1: Grasp the overall question trends
- Round 2: Focus on questions you got wrong
- Round 3: Time yourself to simulate the actual exam
2. Learn Construction Terms in Japanese
The exam is given in Japanese. Make sure to learn the following terms:
- Basic construction management terms — schedule chart (工程表 / kōteihyō), quality standards (品質基準 / hinshitsu kijun), safety equipment
- Material names — rebar (鉄筋 / tekkin), cement (セメント), aggregate (骨材 / kotsuzai), formwork (型枠 / katawaku)
- Legal terms — Industrial Safety and Health Act (労働安全衛生法), Construction Business Act (建設業法), Building Standards Act (建築基準法)
3. Fade Learning: Native Language → Japanese
Start by understanding the content with explanations in your native language, then gradually shift to Japanese-only study.
- Level 1: Study with native language explanations ON
- Level 2: Study with limited native language explanations
- Level 3: Study entirely in Japanese
This method allows you to improve both content understanding and Japanese ability simultaneously.
4. 30 Minutes of Daily Consistent Study
Research shows that studying 30 minutes daily is more effective for memory retention than long study sessions.
- Use your commute time
- 15 minutes during lunch break + 15 minutes after work
- Track your streak (consecutive study days) to maintain motivation

Frequently Asked Questions
Q. How many times can I take the Tokutei-Ginou Level 2 exam?
There is no limit on the number of attempts. You can retake the exam as many times as needed. However, since the exam is only held a few times per year, it's important to plan your exam schedule carefully.
Q. Can I take Level 1 and Level 2 at the same time?
You cannot take both simultaneously. The typical path is to take the Level 2 exam after obtaining Level 1, but you can take the Level 2 exam itself without having Level 1 status (following the 2023 policy change).
Q. Do I need the JLPT (Japanese Language Proficiency Test)?
There is no JLPT requirement for the Tokutei-Ginou Level 2 exam. However, since the exam is given in Japanese, having N3 to N2 level Japanese ability is advantageous.
Q. What is the process after passing?
After passing the exam, you apply for a change of residency status at the Immigration Services Agency. The review process takes approximately 1 to 3 months. It is common for the employing company to support the application process.
Q. How long do I need to study?
It varies by individual, but 3 to 6 months is a good guideline. If you already have practical experience from Level 1, 3 months may suffice; if starting from the basics, plan for 6 months. Studying 30 minutes daily is the fastest path to passing.
