Abstract
This paper aims to discuss the historical backgrounds of in-company English education, its significance, and its future possibility to become an English education system for businesspersons in Japan. Japanese companies have been conducting English education to their employees since just after World War II. Nowadays, with the increasing globalization of company activities, English is becoming increasingly essential for businesspersons, and companies are making more efforts to improve the English communication skills of their employees. In-company English education has contributed to business persons' English learning, achieving positive results. Although in-company English education is sometimes regarded as "human resource management", not "education," it should be seen from a new perspective for English education system for businesspersons.
