Thank you for access to our website.

I am Masanobu Watanabe and president of this company. I founded this company in 2007. At present, we are installing various types of housing equipment, including electrical work, waterworks and gas work.

From 2016 July to 2018 July, I was JOCV (Japan Overseas Cooperation Volunteer) and working at vocational training institute in Bhutan as a plumbing instructor.
Bhutan is a small country in Asia. They live very modestly. It was such a great experience for me.

I want to continue to support developing countries. I can help for technical support or education. If you want to learn Japanese high technology technical for electricity or plumbing, please contact me.
Especially for vocational school or technical institute or electrician or waterworks company.

Thank you.
