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.

Junior Kindy Class

chiharu profile pic Name: Chiharu Yamaguchi
Role: Homeroom Teacher
Experience: 8 years daycare & Kindergarten teaching children aged 0-12 in Canada, 2 years’ experience at an educational consulting company in Canada as an office assistant and writer.
Level of Academic achievement: Diploma in: Early Childhood Education, Care with special needs education, and infant & toddler education at Vancouver Island University. Currently enrolled in BA in Early Childhood Studies at Ryerson University.
Hobbies: Dancing, singing, photographing cooking and eating!!

Hello there!! I was born in Japan, but lived in Canada as a resident for many years,
so I am bilingual in both English and Japanese. I studied Early Childhood Education at University in Canada and got my teaching license in Canada.
After completing my studies, I worked at daycares and a kindergarten in Canada as a classroom teacher, mostly for toddlers and 3-5 year-olds.
I also have experience teaching school aged children. As Canada is a multicultural country, many of the children and families that I worked with came from different countries where English was not their first language; however, I have helped these students gain English, oral and written, through various fun activities and daily life routines.
I saw many students whose English ability went from little understanding to graduating with high English proficiency; therefore, I believe that children can expand their English skills from 0 to 100 depending on the environment they are put in at an early age. The experience I have gained as an educator in different countries where various cultures co-exist has taught me so much about the world and how important it is to think globally.
I am very confident and will make sure that the students at AIWIN learn in an environment that is inspiring, motivating, and fun so as to maximize their possibilities. Alongside English skills, I will also help the children with their “human skills”.
I will strive to help them learn and grow as independent individuals who can think globally, problem-solve, and express what they want and who they are on their own. I am very excited to see the students grow at AIWIN and to bond with their families!!
