Our Humble & Colourful Beginnings

Siliwangi has a very long and colorful history, it started in the mid 70’s as a hobby. It’s founder Hien Shimokawa an Indonesian of Japanese descent was an avid electronics engineer and enthusiast who lived in Semarang Indonesia. He used to play around with anything that had electronic components and he used to break apart anything with electronics in his garage just to figure out how they work and put them back together. Soon after neighbours found out this uncanny ability to fix any broken electronics without any guide or system diagram.

Everyone in the vicinity used to go to his garage to get radio, television and computers for his expertise in repairing electronics equipment and he did not even ask for any payment for his services. He gets his satisfaction in knowing his neighbour have someone to help them out with their electronics problems. Through the suggestion of his better half Mrs. Iswani Kosasih, who would later become the first Chief Executive of the company encourage him to open a small electronics repair shop as a part time work just to cover his expenses for help he is providing his neighbours.
