⭐ Tailored Japanese Lessons in English, Korean, or Basic Spanish/Italian ⭐ Comprehensive Support to Build a Strong Foundation for Mastery.
I'm a native Japanese speaker from Nagano in Japan, who is currently living in South Korea. I had moved around a lot in my childhood. This enabled me to acquire not only standard Japanese but also several Japanese dialects.
After traveling in Asia and Africa, I realized there are so many languages and cultures in this world. Since then, I have become a language enthusiast. Thus far, I have learned several languages, and this has helped me conduct easy-to-understand and customized classes for students with diverse language backgrounds. My lessons & teaching style

As 2023 concludes with today's lesson, it’s time to reflect on a year and a half of learning Korean! I am deeply and incredibly thankful for discovering Sato! While I began the year familiar with many words, now I can engage in basic Korean conversations. My proficiency in conjugating between past, present, and casual to polite tenses has grown significantly. Sato's teaching skills are evident; he gauges precisely when to challenge me and when to allow independent exploration. Whenever I struggle with a concept, his patient explanations ensure clarity. He will always keep at it until I have fully grasped the topic. His organized Google Docs of lesson notes are invaluable, and his commitment shines through—even when responding to late-night questions! Beyond language, Sato also adds invaluable insights into Korean culture and lifestyle. His meticulous attention to my pronunciation ensures I sound as authentic as possible. Truly a dedicated and skilled instructor! Thank you!

Another fun and very helpful lesson with Sato-sensei!
I appreciate his patience and understanding when I forget vocabulary or make mistakes. And I'm super enjoying the pace and really am absorbing the new information well.
I also enjoy all the cultural and language context that he gives as we go through the lesson. It gives so much more life and meaning to learning Japanese.
I also found it very easy to study up on the previous lesson thanks to the Google Doc notes and organization.

During this lesson we spent the majority of it covering faults that I still possess in the negative forms of verbs. For examples,
ます+ない/なかった implies that something is not/wasn't done and it will not be done. While
て+ない/なかった implies something is not/hasn't been done but is still intended to be done in the future.
朝ごはんを食べなかった <- I haven't eaten breakfast and won't (it's too late/I don't want to)
朝ごはんを食べない <- I will not eat breakfast
朝ごはんを食べてない <- I haven't eaten breakfast but intend to (can still eat breakfast)
朝ごはんを食べなかった <- I haven't eaten breakfast (it's too late though I wanted to)
朝ごはんを食べなかった <- I haven't eaten breakfast and won't (it's too late/I don't want to)
朝ごはんには食べない <- I do not eat breakfast (as a rule)
朝ごはんには食べなかった <- I didn't eat breakfast (as a rule)

As another year studying with Sato San is finishing, I feel the need to write a proper review. A new year's resolution two years ago changed my life, I decided to try learning another language and shortly after discovered Sato San. Looking back after almost 100 lessons it is hard to believe we've come so far. Starting from scratch, we are now conducting class in almost exclusively Japanese. I am still far from proficient, but feel like I have an extremely solid foundation to build my intermediate level Japanese on. Sato San's style of teaching puts the ball in your court as a learner. The amount of information and study material he provides is abundant, its up to you as a student to study and apply. We have come a very long way together and I am very grateful as a student to have found such a great guide on my language Journey. We continue to trudge towards the metaphorical peak of Everest together.
Sato San- 本当に ありがとうございました

We worked on more examples for using と for the 事実的条件 scenario, and discussed about the transportation options from Korea to Japan for conversation practice. Thank you for another fun class!
