Assistant Language Teaching in Japan

What's an ALT?

An ALT or Assistant Language Teacher is a title coined by the Japanese Ministry of Education, Culture, Sports, Science and Technology or MEXT for short. ALT is used to describe native-level English speakers working in Japanese classrooms.

Interac’s ALTs work across a broad range of schools throughout Japan, from elementary to high school ALTs. Some of our assistant language teachers are assigned to at least two school levels. The most common pairing for the ALTs roles are elementary schools with junior schools, with more time given to junior high school teaching throughout their roles.


Assistant Language Teachers can expect to teach their own classes, accompanied by a Japanese teacher to help manage the classroom. In rare circumstances, ALTs will work under the guidance of Interac as an employee and not as a member of the Japanese schools staff.


An ALTs job is combining a language instructor and a cultural ambassador. These aspects of an ALTs role are inseparable. After the comprehensive initial training programme, you’ll become an expert in all aspects of assistant language teaching.

Our ALTs

Thousands of ALTs have chosen Interac throughout the years. No matter what stage of life you’re in, background or country of origin, our ALTs are flexible, open-minded and always have a sense of adventure.

ALTs who apply and join Interac from outside Japan are mainly soon-to-be university graduates in their early twenties. Compared to ALTs who apply from within Japan, who tend to be slightly older with more teaching experience. Many of our ALTs actually join from other areas of the world, with years of experience in other vocations ranging from law to advertising. We even have assistant language teachers from other areas of Asia, such as China or Korea.
