University student looking to be an Assistant English Teacher for the Summer

Hi everyone, I am a second year university student (M20) from Canada and I am looking to try getting a job as an assistant english teacher in japan next Summer, don’t care where. I am in the process of getting my Bachelors of Education, and my majors are English and History (finish in 2026). Additionally, I have worked as a teacher and assistant teacher at a children’s school for the last 5 years. I wanted to know if it would be possible to actually get a job as an assistant english teacher for the summer, or find some other employment in the education sector in Japan?
