Iwashimizu Hachiman-gu Shrine and Edison Memorial

April 18 is Invention Day.

On April 18, 1885, 'Monopoly Patent Ordinance,' which was the predecessor of the current 'Patent Act,' was promulgated.

It is said that the Japanese patent system started with this.

After that, on April 18, 1954, "Invention Day" was established by the Institute of Invention and Innovation.

When it comes to inventions, Thomas Alva Edison probably comes to mind for many people.

Inventor Edison created about 1,300 inventions in his lifetime.

Actually, Iwashimizu Hachiman-gu Shrine that I introduced the other day has a lot to do with an invention of Edison.

Edison says he has been experimenting with extending the life of incandescent carbon bulbs since around 1878.

At that time, cotton was used for the filament, but the drawback was that the life of the light bulb was short.

One day, Edison found a Japanese fan in his laboratory and made a prototype filament for a light bulb using the bones of the fan.

The bone is made of bamboo, which is thick and strong, and has been able to prolong the life of light bulbs.

In search of the best bamboo, Edison sends researchers to various countries and a researcher visits Japan.

In Kyoto, the researcher met the bamboo of Otokoyama where Iwashimizu Hachiman-gu Shrine is located.

Yahata's bamboo filament light bulbs have the longest life among all the bamboo collected from around the world.

It is said that it kept lighting for more than 1,000 hours on average!

Japanese bamboo kept illuminating America until the filament of the electric bulb cellulose was invented.

Because of this, a monument of Edison was built in the precincts of Iwashimizu Hachimangu Shrine.

The Edison Birthday Celebration is held on February 11 and the Edison Memorial Celebration is held on October 18.

Edison Ema (votive picture tablet) is also unique!

There is a street named "Edison Street" in front of Keihan Iwashimizu Hachiman-gu Shrine.

There are also statues of Edison and objects of bamboo and incandescent light bulbs. It is truly a town of Edison and bamboo!

"Cafe CANDLE" on Edison Street is also known as "Otokoyama Edison Association".

In the store, Edison's materials that the owner collected are displayed.

Unfortunately, it was a regular holiday, but I would like to visit again.

It's good to think about Edison's invention while drinking coffee.
