Hi! I’m Kosuke, a Japanese business pro (16yrs) turned teacher.
Having mastered English at 30, I deeply understand adult language struggles.
Raising bilingual kids in Australia lets me teach *real-world Japanese* beyond textbooks. I aim to produce natural translations between English and Japanese.
While I geek out on history hikes and subcultures, I’ll tailor lessons to **your** goals –
whether it’s job interviews, daily chats, or nailing those tricky grammar nuances!Me as a Teacher

I had been learning Japanese on my own so far but got stuck because the grammar became hard to remember. Kousuke先生 has been very good at filling in the existing gaps and progressing my learning, regardless of the chapters from Genki - we go through the textbook depending on what he notices I need to work on. This is really helpful, especially since I picked up bad habits through not practising with others.
He is also patient, corrects all my mistakes so I'm confident that I can form better sentences over time, and he is happy to answer any of my questions, whether it's "what sounds more natural" or "how would I say this".

I've been studying Japanese intensively with Kosuke-san for the past four months, and I couldn't be happier with the progress I've made. Under his guidance, I successfully completed Genki 1, a milestone I'm incredibly proud of. Kosuke-san is an exceptional teacher whose expertise and dedication have been instrumental in my language journey. I highly recommend him to anyone looking to learn Japanese.

Absolutely a great teacher! He's patient, kind, and goes above and beyond to teach authentic Japanese expressions used by locals in real conversations. His teaching style makes learning enjoyable and practical. I've noticed significant improvement in my conversational skills thanks to his guidance.

Kosuke Sensei is great! We just started Genki 2. He is patient with me when I need help understanding a lesson and is great at explaining each of the lessons in Genki 1 and 2.
He does a great Job of coming up with questions in addition to the Genki textbook to help further study each of the concepts.
I have been studying with him once a week for about six months. He has been exactly on time and fully present for all of those lessons. He has also been really great about figuring out when I need additional time with a lesson before moving on to the next one.
I highly recommend Kosuke sensei.

Kousuke sensei helped me with specific language nuances that I need to review in my Japanese language study. It helped me to learn what specific points I can learn and practice.
