Enhancing the quality and speed of human decision-making processes.
Automating tasks that do not require human intervention.

eftax Co., Ltd. is dedicated to achieving these objectives with the help of data analytics.


In today’s rapidly changing landscape, characterized by movements like “Society 5.0,” “work style reform,” and “digital transformation,” enhancing operational efficiency and productivity is paramount. However, at the core of these advancements lies the importance of people.

Leveraging technologies such as AI and IoT, we enable the automation of routine operations, formalize tacit knowledge possessed by skilled workers, and provide valuable business insights from vast datasets. As a result, the scope of tasks suitable for technological substitution continues to expand.

Yet, the role of people remains pivotal. People drive occupations and services, add value to society, and pursue self-fulfillment. We recognize the significance of this human element.

Our mission extends beyond technological advancements; we strive to contribute to the realization of a society where the diverse ideas, values, abilities, and experiences of all individuals are embraced and empowered. By placing people at the center of our technological endeavors, we aim to create a more inclusive and prosperous future.
