Society is always changing, but the need for electric meters remains the same.
They are a critical part of social infrastructure, and quietly continue to tick away.
Thus we identify the things that change and those that do not, and adapt accordingly.
As a member of the Shikoku Electric Power Group, we have been expanding our business without changing our focus on electrical supply systems and electronic technology centred on measurement and control. We make your future brighter, more fun, and more comfortable, which allows us our business to grow and makes our customers, employees and their famillies, and the general public smile.
We are Shikoku Instrumentation Co., Ltd. also known as Yonkei.
