What is the Japanese Language Proficiency Test (JLPT)?
The Japanese Language Proficiency Test (JLPT) is a test aimed at foreigners to measure their Japanese language proficiency. Every year, more than 500,000 foreigners around the world take this test.
In fact, as the number of people learning Japanese around the world is increasing, the number of people taking the Japanese Language Proficiency Test continues to increase every year.

Why we recommend this test
First, answer this question.
- Are you wondering if your Japanese is correct?
- Do you want to know your Japanese level?
- Do you want to learn proper Japanese grammar and expressions?
- Do you want to work in Japan as a doctor, nurse, caregiver, or other medical professional?
- Do you want to have Japanese friends at school or work?
If you answered "yes" to any of these questions, then you should take the Japanese Language Proficiency Test. From my experience teaching Japanese to international students, I can say that if you study hard for 10 months, you can pass the N3 or N4 level. You can buy your own textbooks and study every day, or you can practice conversation with Japanese people. It is also possible to take Japanese language classes at a reasonable cost. If you live in Japan, I highly recommend you take a look.

Where can I take the exam?
The exam can be taken twice a year in various locations across Japan, and once or twice overseas.
If you are taking the exam in Japan, you should apply as early as possible because there is a limit to the number of applicants for this exam.
Otherwise, you may end up taking the test in a location other than where you live.
Be patient and relaxed
Once you open the textbook, be sure to read it through to the end.
It is best to avoid having several textbooks open at the same time, and if you want to try a different textbook, do so only after you have finished the first one, as you may be confused by different interpretations and teaching methods, which will destroy any confidence you may have gained.
Also, studying Japanese is not boring or difficult. Imagine what you will be able to do in Japan in the future. You will be able to have fun conversations with Japanese friends and colleagues, and even read and watch your favorite manga and anime.
do your best!
