Beginning in April 2022, fifth and sixth grade students in Japan's public elementary schools will have different teachers for different subjects — a change from the current system where a homeroom teacher essentially teaches everything from math and science to physical education.

The dramatic revision is aimed at easing the burden on teachers — who currently must prepare for all subjects — and allow them to refine their teaching skills and improve their students' learning experience.

At present, Japan's elementary school homeroom teachers basically teach every class, but once those students reach junior high and high school, they are taught by different teachers depending on the subject. This new revision is expected to make the transition for primary school to junior high smoother.
