The Japanese first encountered electricity on March 25, 1878, when an arc lamp was switched on at the Institute of Technology in Toranomon, Tokyo. At this time, electricity was still a novelty in Japan, as well as in Europe and the United States. In the following years, Japan rapidly developed its electrical infrastructure, with Tokyo Electric Lighting, the nation's first electric power company, commencing operations in 1886 and supplying electricity to the public from 1887 onwards. By 1896, there were 33 electric companies established throughout the country. This development continued into the 20th century, with the establishment of long-distance transmission technology and the introduction of larger thermal and hydropower plants, which reduced generation costs and led to the wider adoption of electricity.

What You'll Learn
The first use of electricity in Japan
In the early days, electricity usage in Japan grew primarily for lighting due to its safety and cleanliness. Gradually, electricity found broader applications as a power source, replacing the steam engine. By 1886, Tokyo Electric Lighting, a private company, began operations as the nation's first electric power company, supplying electricity to the public in the following year.
The early 20th century marked the establishment of long-distance transmission technology, and the introduction of larger thermal and hydropower plants. As a result, generation costs decreased, and electricity became more widely used throughout the country, becoming an indispensable energy source for people's lives and industry.
During the First World War, the electric utility industry experienced a major restructuring, leading to the dissolution of 700 electric companies. They merged to create five major electric companies: Nihon Hatsusoden Co., a nationwide power-generating and transmitting state-owned company, and nine distribution companies.
After World War II, supply and demand for electricity in Japan remained tight. Intense discussions were held on restructuring the electric utility industry to democratize the economy. As a result, nine regional privately-owned and managed General Electricity Companies were established in 1951, assuming responsibility for supplying electricity to each region. This fundamental structure remains today.

Early electrical engineering education
Japan first started using electricity on 25 March 1878 when an arc lamp was switched on at the Institute of Technology in Toranomon, Tokyo. At this time, electricity was still unfamiliar and uncommon in Japan, as well as in Europe and the United States.
The early adoption of electricity in Japan was driven by private companies, with Tokyo Electric Lighting becoming the nation's first electric power company in 1886 and beginning to supply electricity to the public in 1887. The use of electricity initially grew primarily for lighting because of its safety and cleanness and gradually found broader applications as a power source, replacing the steam engine. By 1896, there were 33 electric companies established throughout Japan.
The early 20th century marked the establishment of long-distance transmission technology, and the introduction of larger thermal and hydropower plants, which reduced generation costs and led to the wider use of electricity throughout the country. During this period, the electric utility business grew alongside the modernisation of Japan and the development of its industry.
During the Second World War, the electric utility industry was completely state-controlled, with companies integrated into Nihon Hatsusoden Co., a nationwide power-generating and transmitting state-owned company, and nine distribution companies. After the war ended in 1945, supply and demand for electricity remained tight, and a series of discussions were held on restructuring the electric utility industry to democratise the economy. As a result, nine regional privately-owned and managed General Electricity Companies were established in 1951 and were responsible for supplying electricity to each region.
Today, Japan is a hub of scientific and technological innovation, and electrical engineering is a popular field of study for international students. There are several top universities in Japan that offer electrical engineering programmes, including the University of Tokyo, Tohoku University, Kyoto University, and Osaka University. These universities provide a rich cultural experience and a diverse learning environment, attracting over 203,000 international students. Additionally, Japan offers a range of scholarships and financial aid opportunities to support students in their electrical engineering studies.

The role of the Dutch in introducing electricity
Electricity was first used in Japan on 25 March 1878 at the Institute of Technology in Toranomon, Tokyo. An arc lamp was switched on to commemorate the opening of the Central Telegraph Office. At that time, electricity was still uncommon in Japan and the rest of the world. In 1883, Japan's earliest electric utility, Tokyo Electric Light (now known as Tokyo Electric Power, or Tepco), was set up. In 1886, Tokyo Electric Lighting, a private company, became the nation's first electric power company, supplying electricity to the public in the following year. By 1896, the number of electric companies established throughout Japan reached a total of 33.

The establishment of Tokyo Electric Lighting
The Meiji government, in its efforts to modernise Japan, formed an Institute of Technology in 1873. This was around the same time that William Edward Ayrton, the world's first professor of electrical engineering, taught in Japan. Thanks to his dedication, the educational level of Japanese electrical engineering has been estimated to be among the highest in the world.
Japan's earliest electric utility was Tokyo Electric Light, also known as Tokyo Electric Lighting Company, which began operations in 1883, around the same time as other advanced countries such as Britain, Germany, and the USA. Tokyo Electric Lighting was a private company that commenced operations as the nation's first electric power company in 1886, supplying electricity to the public in the following year. In the early days, the use of electricity grew primarily for lighting because of its safety and cleanness and gradually found broader applications as a power source to replace the steam engine.
In 1895, Tokyo Electric Light (TEL) installed 50-cycle a.c. (alternating current) generators manufactured by the German firm AEG. Two years later, Osaka Electric Light (OEL) installed 60-cycle a.c. generators manufactured by the American firm General Electric. TEL and OEL, the two biggest utilities in eastern and western Japan, settled the battle over electrical systems in Japan and laid the foundation for bifurcated cycle standards.
By 1896, the number of electric companies established throughout Japan reached a total of 33. In the early 20th century, the establishment of long-distance transmission technology, along with the introduction of larger thermal and hydropower plants, contributed to the wider use of electricity across the country. The electricity utility business grew alongside Japan's modernisation and industrial development, experiencing a major restructuring that led to the dissolution of 700 electric companies. These companies merged to create five major electric companies after World War I. During World War II, the electric utility industry came under complete state control, and companies were integrated into Nihon Hatsusoden Co., a nationwide, state-owned power-generating and transmitting entity, along with nine distribution companies.

The impact of the Second World War
Japan's electricity sector has a long history, dating back to the late 19th century when electricity was first introduced in the country. The impact of the Second World War on this sector was significant and shaped its development in the post-war era.
During the Second World War, the electric utility industry in Japan was completely state-controlled. The industry was integrated into Nihon Hatsusoden Co., a nationwide power-generating and transmitting state-owned company, along with nine distribution companies. This centralized control over the industry continued immediately after the war, with the government focusing on capacity recovery rather than standardization.
The war had a significant impact on Japan's economy, and in the post-war period, the country experienced rapid industrial growth. This growth led to a surge in energy consumption, with Japan's energy consumption doubling every five years in the decades following the war. By 1976, Japan, with only 3% of the world's population, was consuming 6% of global energy supplies.
To meet this growing demand, Japan diversified its energy sources. The country had already been utilizing hydroelectric power, with small hydropower plants accounting for 6.6% of its total hydropower capacity in September 1971. In the post-war era, Japan further developed its renewable energy sources, including geothermal power and solar power. Japan's geothermal energy sector leverages the nation's volcanic activity, positioning it among countries with high potential for renewable energy development.
Nuclear power also became a significant component of Japan's energy mix after the war. With assistance from the United States, Japan developed its nuclear power program, importing technology and obtaining uranium from various countries. However, following the Fukushima nuclear disaster in 2011, public confidence in nuclear power was greatly damaged, leading to a shift towards renewable energy sources.
In conclusion, the Second World War's impact on Japan's electricity sector was profound, leading to state control during the war and a focus on capacity recovery in the post-war period. The war's impact on Japan's economy and industrial growth also influenced the development of the electricity sector, with the country diversifying its energy sources and experiencing a surge in energy consumption.
