History

The museum contains some unique items, including a "pin insulator for communication" manufactured in 1875 that is believed to be the oldest domestic Japanese insulator.^{[citation needed]} It has "approximately 5,000 pieces of insulators and maintenance tools from 21 countries... and 57 manufacturers."^[1] About 300 pieces are on display at any one time.^[1] It also has a detailed and informative display on the material, processes and applications.

NGK Insulators is one of the world's largest manufacturer of electrical porcelain, with a number of plants in different countries.^[2] Due to the company's significant production of ceramic items, its annual sales exceed $USD3.5 billion. NGK Insulators has been producing porcelain continuously for nearly 100 years, and, sometime in the mid 1980s, its total output surpassed 150 million porcelain units.
