i dont know the basis of the name, but as the company was founded in the 50's it was oriented to export, and needed a name that would work with western alphabet. It was Mr Kobayashi's father who started the company and it is still, more or less, a family owned company.
We keep associating it with our Bessa's, Zeiss Ikon,s etc, but the main business is making optics for lots of other applications, including LCD projectors, high speed surveillance lenses, beam splitters for video recorders and other stuff.
Cosina is also one of the few manufacturers left who makes its own glass. This allows them a free hand when it comes to designing lenses that require specialized glass as they can make a small batch if needed, just for a trial run.
I met Mr Kobayashi in Tokyo almost 10 years ago and over time we have become good friends. He is a delightful man, great sense of humor and an abiding interest in cameras (avid collector), lenses as well as a photographer.
We can spend hours or days when time allows talking about "what if's" and of course having the technical know how available, many of these what ifs become realities!
Oh, he does wear glasses most of the time and he is not interested in golf. He is also one of those rare people who can explain optical designs so that even I can understand the why's and why nots of it.
