On 23 November 1963, this site received the first transpacific transmission of a TV signal from Mojave earth station in California, U.S.A., via the Relay 1 communications satellite. The Ibaraki earth station used a 20m Cassegrain antenna, the first use of this type of antenna for commercial telecommunications. This event demonstrated the capability and impact of satellite communications and helped open a new era of intercontinental live TV programming relayed via satellite.

NHK began the world's first direct broadcast satellite service in May, 1984. This was the culmination of eighteen years of research that included the development of an inexpensive low-noise receiver and investigations of rain attenuation in the 12 GHz band. RRL, NASDA, TSCJ, Toshiba Corporation, General Electric Company, and NASA participated with NHK to make satellite broadcasting to the home a practical reality.

Beginning in 1924, Professor Hidetsugu Yagi and his assistant, Shintaro Uda, designed and constructed a sensitive and highly-directional antenna using closely-coupled parasitic elements. The antenna, which is effective in the higher-frequency ranges, has been important for radar, television, and amateur radio.
The antenna system, using a driven element with closely coupled parasitics (usually a reflector and one or more directors) for short-wave work, was first described by S. Uda, a professor at Tohuku University in Japan, in 1926, in the IEEJ (Japan). A colleague, Professor H.

At the Yokohama Plant of Victor Company of Japan, Limited, a team of engineers headed by Shizuo Takano and Yuma Shiraishi developed VHS (Video Home System) format. They looked ahead to the need for home video tape recorders and embodied their idea in unique inventions. The first model JVC HR-3300 was announced on 9 September 1976. Their basic design with subsequent improvement gained wide customer acceptance.

Dr. Takeshi Takei, the professor at the Tokyo Institute of Technology, discovered that composite oxides containing zinc and iron have distinguished magnetic properties. In 1930, Prof. Takei submitted a paper on his work to Japanese Electro-chemical Society and also presented a paper at 57th General Meeting of American Electrochemical Society in St. Louis. That same year, Prof. Takei applied a patent for his discovery, which was granted in 1932(Japan PAT-98844).
Tokyo Denki Kagaku Kogyo (now TDK Corporation) was founded in 1935 to commercialize this newly invented ferrite cores.

Professor Kenjiro Takayanagi started his research program in television at Hamamatsu Technical College (now Shizuoka University) in 1924. He transmitted an image of the Japanese character イ(i) on a cathode-ray tube on 25 December 1926 and broadcast video over an electronic television system in 1935. His work, patents, articles, and teaching helped lay the foundation for the rise of Japanese television and related industries to global leadership.
The milestone plaque may be viewed at the site of the research at Hamamatsu Technical College (now Shizuoka University).

In 1954 three researchers at Bell Laboratories published the results of their discovery of the world’s first practical ‘photovoltaic’ (henceforth abbreviated by ‘PV’) cell which was capable of converting sunlight into electricity, first at 4% and later at 6% conversion-efficiency[1]. In 1959 Sharp Corporation began R&D of silicon monocrystal PV-cells, with mass production starting in 1963[2], and commercialized a variety of mono/multi-crystalline PV-cells for everything from satellites to lighthouses, and industrial applications to residential use[2].

In 1964, Shinkansen (which means "new trunk line" and is also known as the bullet train) between Tokyo and Shin-Osaka became the world's first high-speed railway system, running at a maximum business speed of over 200 km/h (130-160 mph).

The Tokaido Shinkansen, the world's first inter-city, high-speed railway system, began operations on its route of over 500 kilometers between Tokyo and Osaka more than thirty years ago, in 1964. After its establishment, the Tokaido Shinkansen made a major contribution to Japan's rapid post-war economic growth as the country's principal transportation artery. Today (1997), more than two hundred and eighty Shinkansen trains operate between Tokyo and Osaka each day, with eleven departures an hour at peak times, and a daily ridership of more than 360,000 passengers.
