Aeon

In 1973, university classmates Kiyoshi Aki and Tsuneo Kusunoki founded the company AMVIC. The name was a portmanteau of the phrase "AMbition and VICtory." The company would focus on foreign language studies. AMVIC International was later split into two divisions in 1989, as the former partners developed differing visions of the company's future. Aki's company became Aeon, focusing on language learning in Japan. He remains Aeon's chairman as of 2010. Kusunoki's company became GEOS, focusing on global language learning. GEOS and Aeon remained competitors until April 2010 when GEOS filed for bankruptcy protection.

In 2018, Aeon joined the KDDI company umbrella. With the merger, Aeon began using KDDI's AI systems to promote student learning. They continue to use AI technology with their Aeon NET Campus App.

Aeon also partnered with the Ministry of Education, Culture, Sports, Science, and Technology to help train teachers in teaching English in Japan's public school systems in 2018. As of 2020, Aeon has continued to train teachers in partnership with the government.

Aeon offers many types of English courses and services. For adults, conversation and grammar courses are available, as well as courses on business English. The company also offers training for various tests, such as TOEIC and J-SHINE courses. The company also provides lessons for young children, elementary, and junior high school students in conversation and grammar skills.
