Yamasaki-san must be now 84 years old.
After the WWII, his father spinned out from Yamasaki Optics Lab (not the photographic lens lab above), the maker of Congo lenses, whose owner is his father’s brother.

The Congo lens story is here.

At first, his father made Taiyo brand LF lenses, but soon stop making the lenses and
focused on lens polishing and coating business.
He still works at the lab with his son.

Old lenses like Leica and LF lenses are brought to his lab from all over the world.

I plan to visit his lab to polish and coat my old zeiss jena tessar 165mm f2.7 as my first visit.
From some of the blogs on the internet, the lens polishing and coating seems to cost starting from 200-300 USD.
