Shift Your Path
Through Japanese

A Japanese education program for students and professionals building their careers. Our conversation-first learning help students reach JLPT N3–N2 and prepare for careers in Japan.

Despite good technical skills, reputable university, extraordinary experiences, and satisfying JLPT level certificate...

A lot of candidates struggled in hiring processes due to conversational Japanese gaps.

We look for the cause

And found a crucial thing.
The Japanese Language Proficiency Test do not test conversational skills.

Compared to other standardized language tests like IELTS, TOEFL iBT, DELF, Goethe-Zertifikat, etc

OKOSHI was born not out of disbelieve in the candidates, rather out of belief in our young talents.

At OKOSHI, we believe that no matter where our students started their Japanese journey from...

Even when they have no idea of hiragana or when they have obtained the JLPT N3 but are still afraid to speak...

They are the exact professionals the Japanese companies are
looking for.

OKOSHI was created not only to open the doors of opportunities.

We are created to hold the doors to open wide still.

For you, the talents who refuse to give up.

For you, the dream candidates who want to shift their life.
