Business Introduction
The Reason for the Existence of the Nareru Group
mainly in the fields of construction and IT.
The construction industry, to which our group’s major customers belong, is facing a serious shortage of skilled personnel, posing a major challenge that will affect the prosperity of countries, industries, and companies. The Nareru Group’s purpose in existence is to convey to the younger generation the joy and reward of the construction and IT industries, and to train them as professionals so that as many young people as possible will be able to take on the future of these industries. We are actively focusing on hiring and training, and by producing many talented people who will lead the future, we are contributing to the future of the industry and society.
Misson
We will solve the increasingly serious shortage of professional human resources*1 and make Japan a “problem-solving advanced country.”
(*1) We define professional human resources as “talented individuals who have skills in a specific industrial field and who are engaged in specialized work.”
Vision
By combining the two technologies of IT and human resource development, we will provide and realize “business transformation to increase productivity” and “development and stable supply of professional human resources” to compensate for the decrease in the number of professional human resources.

Hiring and Training Capabilities Produce Many Professionals Who Will Lead the Future.
The Nareru Group has established a young talent development method and provides tailored training based on engineers’ years of experience, in order to develop them into fully-fledged engineers within 5 to 10 years. This enables our engineers to take on more challenging projects, and the skills they gain there enable them to achieve further growth.
Inexperienced workers | Basic Skills Training | Training on basic knowledge of the construction industry, technical terms, and the basics of essential professional skills. |
2nd to 3rd years | Basic Specialized Skills Training | Training on basic skills to prepare for the next project, based on the experience gained from the initial project assignment. |
4th to 6th years | Practical Specialized Skills Training | Training with a view to acquiring qualifications such as first-class architects and construction management engineers while working on more specialized projects. |
From the 7th year onwards | Specialized Skills Training | Training to lead projects as an indispensable presence on construction sites. |
