Jumpei is an incredible teacher. He always challenges you the perfect amount. I suspect he goals to give you a "Glimps of mastery", where he helps you master the basics in a way that's useful before moving on. I went to Japan after 19 hours of tutoring with him + studying on my own. I could quickly put together simple Japanese sentences on the fly. I could actually interact with Japanese speakers. I actually spent 2 hours hanging out with Japanese speakers I met while hiking near Tokyo. One intense month practicing with Jumpei gave me more foreign language speaking ability than 3 semesters of college English. So if you want to speak Japanese instead of just write it, I recommend having Jumpei train you. Now I've done 39 hours of lessons with Jumpei, and I have much better Japanese. I'm excited about what my next trip to Japan will be like!

I learned so much in this lesson! Jumpei identified specific phrases I often use that accidentally sound impolite, and he carefully explained the problems with each phrase and then taught me what I should say instead. I really appreciated this, and I'm so glad that Jumpei taught me these things! Jumpei is a very attentive teacher. He always notices patterns in my speech and writing, and then breaks down the problems and teaches me how to fix them. Any students who are serious about learning Japanese or improving their Japanese should take lessons with Jumpei.

I like the teacher. I’ve started with zero knowledge but only one lesson I mastered to construct some simple sentences to express myself. Not just simple greeting expressions, e.g. hello and thank you. Excellent teacher

I have taken lessons with Jumpei Sensei for over 6 months. We started with very basic grammar and used various resources to study and practice. He will select, and even create personalized homework to help improve weaknesses and introduce new Japanese grammar and vocab to make learning feel natural. Jumpei Sensei is a professional teacher, and as such is very skilled at explaining the nuances and native flow of Japanese. Every lesson he will help you practice the correct way of speaking and help you figure out how to say what you want to say in the clearest way that your level of understanding allows. I highly recommend Jumpei Sensei as someone who can help serious learners take their skill to the next level. 頑張ってください！ ありがとうございました！

Out of all the Japanese teachers I’ve tried Jumpei is the best. He actually wants you to do well and pushes you to get to where you want to achieve.

Jumpei sensei has a great way of teaching an understanding of the difference between the grammars for giving and receiving which we studied today. He's very challenging and can find your weak points then really press them to help you get past those sticking points! Great teacher and feedback for those who are really wanting to become skilled in conversation, not just textbook material. I learned so much today about how the context of the conversation changes what grammar you choose or the meaning of the reply. It was tough but very targeted towards my level and attainable!
