Workplace Environment

Our team/corporate culture

We always work as a team because there is no work that can be done by one person, both soft and hard. We communicate a lot so that the team can work out what is not clear.
The office is a free address (Determined by automatic lottery, areas are determined by each team), so you can have the same team but different people next to you every day and work with a fresh mind.

Typical daily work schedule

8:00 Meeting
8:30 Business progress meeting
9:00 Work on tasks in charge
12:00 Lunch
13:00 Work on tasks in charge
16:30 Business progress meeting
17:00 End of work or do extra work during overtime

Post-employment and on-the-job training

We have 2.5 to 3 months of professional education.
After that, you’ll have a team of four or five for on-the-job training.

We conduct practical on-the-job training for evaluation and measurement of circuit boards (at least two people per pair), reading and writing circuit drawings, and component selection (often in English).

Are there any senior non-Japanese nationals, or English-speaking employees?

We have one Indian and two Indonesian nationals in Software First Room.

Our employees from abroad

Message from an Indian employee

Japan has been a driving force for innovation and technology around the world. Five years ago, I decided to start my career in Japan due to the ample number of opportunities here.
The opportunity to innovate, to pursue research, and to learn manufacturing from the world’s leading manufacturing hub I have been working in Aisan Industy for the past 3 years in automotive software development.
Aisan has given me the opportunity to work in the core domains of electronics and embedded systems.
And has presented me with various opportunities to learn and enhance my skills in a very fun and cooperative working environment.
I also had the opportunity to file for an individual patent last year, thus giving an upward trajectory to my career.
I hope that many of you will make the most of this opportunity, and maybe we can work together in the near future.
All the best.
