production and finish in an integrated way. The integrated production system improves the detail and quality. For example, when Masunaga Optical develops a new model, the molds are always built in-house. If there is a problem in the wear comfort that can be felt only after completing one pair of glasses, it will be corrected in the previous process’ promptly.
The company’s mission statement since the establishment is “We manufacture excellent eyeglasses. We want to make a profit if we can, but we don’t hesitate to take a loss. It is always in our thoughts to manufacture excellent eyeglasses.” These words are still the basis of the conduct code of employees even more than 100 years after its establishment.
