Tomorrow, March 25, is Electricity Memorial Day in Japan.

The day commemorates the first public lighting of an electric arc lamp in Japan, and it was officially established by the Japan Electric Association in 1927.

🕯 What Happened?
🎉 March 25, 1878

A celebration was held at the Imperial College of Engineering in Toranomon, Tokyo (now part of the University of Tokyo, Faculty of Engineering) to mark the opening of the Central Telegraph Office.

During the event, Professor William Edward Ayrton, a British engineer and educator, demonstrated an arc lamp that he had brought with him.

This became the first successful public demonstration of electric lighting in Japan.

🌟 This historic moment is often referred to as the dawn of electricity in Japan.

💡 What Is an Arc Lamp?

An arc lamp is a type of electric light that produces illumination through an electric arc between two electrodes.

Unlike today's LED or fluorescent lighting, arc lamps generated an extremely bright light along with a great deal of heat. Although primitive by modern standards, they were considered a revolutionary invention at the time.

⚡ Why Is It a Memorial Day?

Nearly 50 years later, in 1927, as Japan's electric power industry continued to grow, the Japan Electric Association designated March 25 as Electricity Memorial Day to commemorate the beginning of electricity in Japan and to promote awareness of its importance.
