Welcome to Aiwin International School where we provide a structured and purposeful English learning environment that allows our children to develop fundamental skills, compassion and confidence into becoming globally responsible citizens. I am very proud to be a part of and lead our professional and talented teachers and staff who dedicate themselves in helping our young learners achieve their fullest potential.
My profession gave me an opportunity to teach and be trained in various educational institutions where I saw how teaching methodologies and school policies could work well together to fulfill the student’s learning needs. It also gave me a deeper understanding of how important it is to consider parents and caregivers as active participants in their child’s education and care. Strengthening the connection between home and school ensures a child’s success not only in school but also later on in facing bigger challenges in life. I believe that creating a balance among education, care and governance gives our children the best and most memorable educational experience.
I would like to see our school become even more remarkable, with professional teachers and supportive parents on board, in molding learners that develop a love for learning and who truly embody excellence. Thank you for choosing Aiwin. Our doors are always open to welcome you.

Hello my name is Emmanuel and I’m from France.
I’ve always been interested in learning foreign languages. So I decided to study them and eventually go live abroad to experience what was life like elsewhere. Consequently, I lived in the U.K, in Italy, Mexico, Kenya and now in Japan ! Experiencing diverse lifestyles helped me understand people better and improve my personality.
Besides French and English, I can speak Italian and I am currently learning Japanese on my own hoping to become fluent one day.
As a teacher, I taught French to English students aged between 10 to 18 in England as an ALT. I prepared my own lessons for each classes to instruct them about both language and culture.
I started to teach English in kindergartens in Japan 3 years ago and it’s a job I really like to do. I taught kids aged 1 to 10 (mostly aged 2 to 4) basic English, art, number & alphabet and more. Creating fun lessons and activities is something I became good at. And Japanese students are the best audience ! As the main teacher in Japan I learned more about patience and different ways to manage the kids by working at different schools where classes and pupils had varied english abilities. That was an interesting challenge for me.
My goal as a kindergarten teacher is to allow kids to have fun while learning. I’m keen to take them to a good conversional English level and work on their the confidence, the knowledge and the tools to become independent and creative youth in the future. My motto is: Knowledge is power !See you at school!
