What we do

  • RJ is one of the best online English! To 40K individuals and 1,000 corporates.

RareJob, as a listed venture business in education industry, has its service Mission,
“Encourage 10 million Japanese people to speak fluent English.”

With “RareJob English,” one of the leading online English services, as the core service, RareJob has been developed largely for the future education. These are a part of what we have done so far;

▼Start business for schools with the aim of a new method of English learning in schools using internet
▼Demonstration test using AI with the cooperation between NEC and RareJob English
▼Distribute the ways to improve English skills steadily through “RareJob English Lab,”
▼Tie-up with Mitsui & Co., Ltd. to set up the infrastructure with online English for English education
▼Tie-up with Z-kai for co-service-development to prepare for university entrance exams

We have seen a recent worldwide expansion of online learning space. And one of the concerns we all have about online learning is “how to keep studying.”
To solve this concern, we have been working on constructing a platform to help users keep studying and improve their English skill not too much depending on their individual motivation.

We believe that the key to acquiring English skill lies in a solution of the multiplication of “Education,” “Technology,” and “Global,” which traditional English service industry could never achieve

Why we do

  • Elementary, junior-high, high schools
  • 20M lessons have been provided

We would like to increase the number of Japanese people who can globally work across the national borders and language barriers both because there are more and more companies that expand their business in foreign countries, there are more and more tourists coming to Japan, and children start learning English at school at the earlier stage than before, and also because we have had difficulties in acquiring English skills, too. Our own experiences as an English learner actually motivate to develop and provide services that solve people’s concerns about English learning.

How we do

  • Business driven Multi-National teams
  • With always user-first perspective

To provide coherent UX, a department in RareJob consists of core members for our services such as engineers, designers, producers, learning counselors.

In weekly meeting on Monday morning, anyone can propose ideas. Sympathy for the ideas brings members together and they work together as a team on the realization of the ideas.

We also review our rules and processes regularly so that our operation goes smoothly without unnecessary process and that members of the team agree with the processes.
