🎓Certified Japanese teacher with a Master’s in Japanese Language Education | 1500+ online lessons | Hello! My name is Koshiro 🌿 I’m based in Osaka, Japan. I love watching anime and talking with people from around the world! 📺🌎 My students often describe me as a kind and supportive teacher 😊 I hold a Master’s degree in Japanese Language Education, specializing in Second Language Acquisition. My research focused on how international students improve their speaking skills and how their social networks during study abroad influence language development. During graduate school, I completed a teaching practicum at a Japanese university and gained experience as a volunteer teacher in local communities and as a teaching assistant in university classes. I have taught learners from various countries and proficiency levels—from complete beginners to advanced—and have conducted over 1500 online lessons. I also hold Japan’s national certification for Japanese language teachers. Lessons focus on building communication skills and are tailored to each student’s level and goals. You can study using textbooks or through free conversation, depending on your needs. Whether you're a beginner, preparing for the JLPT, or learning for travel or business, I’ll support you. 🗣 While I’m not fluent in English, I prepare explanations in English when necessary—so beginners can join with confidence! For all lesson types, I provide a study plan and recommend resources when needed. You’re also welcome to message me with questions anytime—24/7! 📩

こうしろう先生の授業はいつも面白くて、楽しいです。私が間違えても、先生は優しく直してくれます。今まで授業は四回しか受けていませんが、先生のおかげでたくさんのことを学んでいます。きっと、JLPTの試験にも合格しやすくなると思います!先生の授業はおすすめです。 先生、色々なことを教えてくれてありがとうございます! Koshiro-sensei is a very patient and passionate teacher. Even though I've only had four lessons with him so far, I'm already learning a lot. In every lesson, we go through one unit from Shin Kanzen Master (a JLPT preparation book), and once we finish, we spend the rest of the time talking freely. Every time I make a mistake while speaking or reading, he kindly corrects me and teaches me the right way to express what I want to say. I absolutely recommend his lessons!

It was my first lesson with Koshiro sensei, but surely not the last one. We discussed my current level and studied self introduction and numbers. Everything was explained to me in an understandable way in the nice and friendly atmosphere. ありがとうございます!

いつも通りありがとうございました!This was my second intermediate class with Koshiro Sensei using the Quartet textbook. Today we have practised talking about the weather and my daytime job. We have then gone through various grammar points and tried making sentences using them. Koshiro Sensei corrected my grammar and intonation meticulously, and explained why certain expressions sound more natural than others. We went through over the homework assigned last week, with corrections as needed. Overall, I felt that my speaking and grammar skills are slowly but surely improving.

I've been taking lessons from Koshiro for several weeks now and I always look forward to our lessons. We do free talk, and not only is he very friendly and a great conversationalist, but he diligently listens to what I'm saying and makes detailed notes on my grammar and word choices. I feel that my Japanese conversational ability is improving every week thanks to Koshiro, and I highly recommend him if you're looking to improve in your ability to make conversation in Japanese.

Koshiro expained some grammar points I didn't even know I had questions about today. He gave me instant feedback as I was using the incorrect particles and suggested actionable homework to practise on
