It seems that many people misunderstand that the person who invented the light bulb is Thomas A. Edison. Apart from the inventor, Edison is the person who commercialized the light bulb. It is known that the filament was successfully made using Japanese bamboo. The bamboo used was from Otokoyama, Yawata City, Kyoto Prefecture.

The spread of light bulbs has brightened human society around the world. I think the person who did such a big job is really a great man.

There is a bust of Edison in front of Keihan Railway Iwashimizu-Hachimangu Station.
