Do you want to understand your favorite anime show, movies or Japanese culture better? Do you want to learn to crack jokes in Japanese and win any crowd over? Would you like to do business in Japan and need someone who can not only teach you the language, but cultural differences and etiquette so you can win over any client?

Japanese and English are polar opposites in many ways.
Sentence structures are upside down. English is written horizontally left to right, but traditional Japanese is written vertically right to left.
Communicating can be difficult when what can be spoken directly in English has to be said in more subtle ways in Japanese, and this miscommunication can cause relationships to break down.

My passion is to help people cross cultural barriers and make new friends.
Learning a new language can build confidence and expand your mind in ways you never thought possible!

One of the signs that you have truly mastered a language is to understand the humor. I can break down and explain jokes and humor to the point where you’ll be captivating a crowd.
I want to build you up, not only in your speaking, listening, reading and writing ability, but in your confidence, because I believe confidence and charisma is the foundation for communication.
I have also trained in acting and script analysis so I like to use movies and TV shows to teach language in a fun and interactive way.

Let me help you master Japanese!

About Masaki K.

About me.

I was born in Fukuoka, Japan and moved to the US when I was 18.
I studied ESL then got a degree in marketing and worked in Real Estate and Finance for many years.
I learned English from scratch when I moved to California and am now completely fluent in English, so much so that people can’t believe I’m not from here.
My work takes me back and forth between Japan and the US, and I am so grateful to have a deep understanding of both the Japanese and Western way of life and be able to celebrate the two.

When trying to find a tutor, I did a lot of research and ended up picking Masaki as my teacher. I definitely made the right choice because he's great! I like how he stresses the importance of the fundamentals, including the correct pronunciation. His goal isn't just for your Japanese to be "good enough", he wants to make it so that you sound like a native speaker. He doesn't hesitate to correct me, but in a very kind way. I've booked 1-hour lessons with him, but because I learn so much in every class so far, the time always feels so short.

Masaki tailors the lesson to the individual. We had a great conversation on my first lesson and I'm off to a great start! I'm eager to see how far I get!

Masaki fosters a learning environment where he takes all of the hard work of learning a new language transforms it into fun. He has a bright personality, and the ability to not only translate the language, but the language in the context of the culture. He doesn't just teach you to speak Japanese, but how to be Japanese!

Talking to Masaki you would never know that English was not one of his native languages... I'm still shocked that he didn't begin learning until he was already an adult!

If you are wanting to learn Japanese, or if you are Japanese and you want to become as a native English speaker, you have found your guy!

It's hard to believe Masaki could become so fluent at a second language when he only started learning at the age of 18. It makes him a great teacher for adults because he himself started a second language as an adult.

His teaching style is so fun and so tailored to each student I highly recommend him as a language teacher, both in Japanese and English!
