​Functional Body ＆ Mind Academy 

When I started learning Japanese with M-san, I knew I needed more than just textbook exercises—I needed a teacher who could adapt to my pace, my schedule, and my way of learning. M-san has been exactly that. She is exceptionally patient, attentive, and dedicated, always taking the time to ensure I truly understand each concept before moving forward. What makes her stand out is her flexibility: she has seamlessly accommodated my agenda and travel constraints, making consistent progress possible no matter where I am.

 

Her approach is thoughtful and thorough, and her feedback is always clear and constructive. Learning with her has not only improved my Japanese steadily but has also made the process genuinely enjoyable. If you're looking for a language teacher who combines professionalism with genuine care for your progress, I cannot recommend M-san highly enough.

J’ai commencé à apprendre le japonais avec M-san l'année dernière, et je cherchais un enseignement adapté à mon rythme, à mon emploi du temps et à ma façon d’apprendre. M-san a parfaitement répondu à ces attentes. Elle fait preuve d’une patience, d’une attention et d’un dévouement exceptionnels, prenant toujours le temps de s’assurer que j’ai bien assimilé chaque notion. Sa flexibilité la distingue également: elle s’est parfaitement adaptée à mes contraintes d’agenda et de voyage, ce qui m’a permis de progresser de manière constante.

 

Sa méthode est réfléchie et rigoureuse, et ses retours sont toujours clairs et constructifs. Grâce à elle, mon apprentissage du japonais progresse de façon régulière et agréable. Si vous recherchez un professeur de langue alliant professionnalisme et recherche de résultats , je vous suggère de contacter M-san.

As a complete beginner in kettlebell training, I couldn't have asked for a better instructor than M-san. She has been incredible at onboarding me, patiently building my skills from the ground up with unwavering dedication. Her feedback is always thorough, thoughtful, and constructive, helping me correct form and progress safely.
This has been well worth the investment—if you're serious about starting with the right foundation, it's essential. Kettlebell movements are complex and demand excellent coordination, and self-learning from videos or books alone is clearly insufficient. Training with M-san has been an eye-opener and a true fast-track to gaining good control and confidence.
Highly recommended!

En tant que débutant complet dans l'entraînement avec kettlebells, je n'aurais pas pu rêver d'une meilleure instructrice que M-san. Elle a été formidable pour m'intégrer, en construisant patiemment mes compétences dès les bases avec une dedication sans faille. Ses retours sont toujours approfondis, réfléchis et constructifs, m'aidant à corriger ma forme et à progresser en toute sécurité.
Cela vaut largement l'investissement — si vous voulez commencer avec les bonnes bases, c'est essentiel. Les mouvements avec kettlebell sont complexes et exigent une excellente coordination, et apprendre seul via des vidéos ou des livres est clairement insuffisant. Les cours avec M-san ont été une révélation et un véritable raccourci vers une bonne maîtrise et confiance.
Fortement recommandé !

I had a few online introductory kettlebell lessons with Migiwa, which were very good. I wasn't sure how effective the online format would be, but Migiwa explained everything simply and clearly, gave me good feedback on my form and I felt that I made great progress. I'm planning on taking more lessons with her in the future.

I currently live in Tokyo and hold an SFG1 certification.
To review the fundamental movements and receive direct instruction on SFG2 techniques, I asked Coach M, who is SFG2 certified, for a session. As a Brazilian Jiu-Jitsu athlete, I have a solid level of base physical strength. However, I’m aware that I tend to compensate for poor form with brute strength when using kettlebells. Coach M provided precise feedback and corrections in those areas, making the session extremely educational and valuable. Whether you're a beginner or an aspiring instructor, I highly recommend Coach M’s instruction for improving your kettlebell skills!​

現在、都内在住でSFG1を保持しています。基礎種目の再確認と、SFG2の種目を直接ご指導いただくために、SFG2認定をお持ちのM先生に指導をお願いしました。私はブラジリアン柔術のアスリートでもあり、基礎体力には自信がありますが、ケトルベルではフォームの乱れを力で補ってしまう瞬間があることを自覚していました。その点についても、M先生から的確なフィードバックと修正をいただき、大変学びの多い時間となりました。

初心者の方はもちろん、インストラクターを目指す方にも、ケトルベルスキル向上のためにM先生の指導をおすすめします！

半年間、アニマルフローとファンクショナルトレーニングのレッスンを受けています。
毎回、希望やレベルに応じたバラエティに富んだメニューを組んでいただき、フォームや力の入れ方などを細かく指導していただけるので、短期間で身体能力の向上を実感できています。
また、いい感じに(？)追い込んでくれるので、楽しくキツくトレーニングできています。

I took four one-hour in-person kettlebell lessons with M-san. She is highly knowledgeable, thorough, and excellent at explaining the basics of kettlebell training. Her feedback helped me improve my form and gave me the confidence to train safely. She speaks excellent English, is friendly, and makes learning an enjoyable experience. I highly recommend M-san to anyone looking to improve their kettlebell skills. ありがとうございます。

近所で運動の機会を作りたくてレッスンを受けていました。ファンクショナル系のトレーニングに興味があったのでジャンルは希望どおりでした。グループレッスンですが、体力や体調に合わせて各自の強度・ペースでできるのがいいと思います。時にきついですが、仲間がいるので刺激になりますし爽快感を共有できて楽しいです。

I had a total of 8 online lessons with M sensei. I learned the basics of kettlebell swing, Turkish Get Up, clean, and other exercises for overall preparing the body for KB workouts. She has been very thorough and detailed in her instructions. She is a very dedicated instructor; she would send me videos of myself after each lesson, spending extra time explaining where I did well and where I didn't. If you want to really learn the foundations of KB well from the beginning, I recommend taking a class with M sensei.
非常に詳しく丁寧に説明してくれる先生です。レッスン後も前回のレッスンで自分がどこをよくやってどこがまだだめなのかを説明してくれる動画まで送ってくれるDedicationの高い先生です

I have taken several online lessons from M-san.

I have learned the various essentials of kettlebell training.

I think it is difficult to improve in kettlebell handling on one's own, because what is missing or what is needed is different for each individual.

I strongly recommend, especially for beginners, to be checked by an experienced instructor like M-san from the early stage.

 

M先生からはオンラインレッスンを数回に渡り受けています。

ケトルベルのトレーニングの様々な要諦を学ぶことができました。

ケトルベルの扱い方について、どこが足りていないか、何が必要かは個人個人で異なるため、独学では向上が難しいと思います。

特に初学者の方には、M先生のように経験豊かな指導者に見ていただくことを強くお勧めします。

海外勤務に必要な日本語の級を取得して日本に転勤しましたが、外国で教科書で学んだ日本語だけでは、日本での生活や仕事に関する会話では、何か表現の仕方が不自然で物足りなさを感じていました。 実生活で使える日本語表現などを学びたいと思い、チューターレッスンを受けるようになり、少しずつレベルアップしていくのを感じることができました。 レッスンを通して、教科書ではなく、実生活で使われる様々な表現を学ぶことができ、会社でも会社以外の日常生活でも、より自然な会話ができるようになり、自信もついたと思います。 とてもおすすめです。​

 

해외근무시 필요로하는 일본어 등급을 딴 후 일본으로 전근을 했지만, 외국에서 텍스트북으로 배운 일본어 만으로는 일본 현지 생활이나 업무 관련 대화에 있어서는 뭔가 표현 방법이 자연스럽지 못하고 부족한 느낌이 들었습니다.  실제 생활에서 만날 수 있는 일본어 표현 등을 배우고자, 튜터 레슨을 받게 되었고, 조금씩 레벨업 되어가는 것을 느낄수 있었습니다.  레슨을 통해 텍스트 북이 아닌 실제 생활에서 쓰이는 여러가지 표현들을 배울 수 있었고 회사에서도 회사밖 일상 생활 중에도 좀 더 자연스러운 대화가 가능해져 자신감도 더 생겼던 것 같습니다. 적극 추천합니다.

I had two online lessons with M to learn the basics of the Swing and Get-Up for Simple and Sinister. She really took the time to closely look at and also correct my form. She gave me instructions on how to overcome my weak points with each exercise and my performance has improved considerably since then. She also showed me how to properly do the mobility exercises in Simple and Sinister. I will continue to take online lessons from her in the future.​

 

シンプル＆シニスターのスイングとゲットアップの基本を学ぶために、Mさんと２回オンライン レッスンを受けました。Mさんは時間をかけて私のフォームを注意深く見て修正してくれました。各エクササイズで自分の弱点を克服する方法を教えてくれました。それ以来、私のパフォーマンスは大幅に改善されました。また、シンプル＆シニスター のウォームアップの正しい方法を教えてくれました。今後も彼女からオンラインレッスンを受け続けようと思います。

Had a remote session with M to clean up my kettlebell swing technique. She took me back to the basics and gave clear instructions on what to improve. Highly recommended.

My wife and I have been practicing with kettlebells on our own for six months when we realized it was time to call in a PT to give us advice on our form and future progression. Migiwa sensei's instruction was clear and carefully calibrated to our personal needs, helping us to clean up our technique and take our training to the next level. We will continue to rely on her in future training sessions, and I recommend her without hesitation.

I was a bit skeptical with my decision to take virtual kettlebell lessons, but given the current environment (COVID-19), decided to give them a try. It was clear after the first lesson that my concerns were unwarranted. Nagi proved to be an excellent teacher with a keen eye, who could spot errors in my swing over our Zoom sessions. I originally had planned for the single lesson, but after a number of lessons, we are still at it.

Nagi has helped my technique so much! She was incredibly accommodating during a time where it is difficult to get into a gym, and set up a video session that I was able to do from my home. She took the time to patiently help me with my technique and I'm still feeling the benefits of it. Sign up for her online sessions and you won't be disappointed!!

Nagi is an excellent instructor. My wife and I both recently started exercising with kettlebells and wanted to be sure our form was correct. COVID and convenience had us looking for local instructors willing to hold online sessions, which led us to Nagi.Nagi is incredibly flexible and extremely motivating to learn from. Her explanations and demonstrations of the movements are very clear and easy to understand, despite the limitation of online video (and in both English and Japanese!). After just our first 1 hour session, swings feel so much better! Looking forward to continuing our training!
