Translated from their website:

Ishizawa Laboratories was founded on Christmas day in 1989 with the idea of introducing a variety of unique and distinctive products to the world, just like turning a surprise box upside down.

They began in a small room in an old building with gray sooty walls and sunlight in the west. The walls, floor, and even the ceiling were repainted pure white, and the company was launched with the goal of becoming clean and transparent without a trace of cloudiness.
