"Expo" is an abbreviated name for "World Exposition". A World Expo is an exhibition that brings together and showcases the culture and the latest technologies from all over the world.

The Expo is an event where many people and goods gather from all over the world to address various issues of the entire planet. It is an “opportunity” for new technologies and products to be born and for our lives to become more convenient.

The first World Expo, 1851 London Expo was held in England with 25 countries represented. The first Japanese exhibit was at the 2nd Expo, 1867 Paris Expo held in France.

The first World Exposition in Japan was held in Osaka in 1970. Its theme was "Progress and Harmony for Mankind." The latest technologies from around the world were gathered, and many people from home and abroad visited the Expo. The Tower of the Sun, which was built at that time, can still be seen at the Expo '70 Commemorative Park.

The Tower of the Sun bears three faces that can be seen from the outside. The first face is the Golden Mask located at the top of the tower, which shines golden and represents the future. The second is the Face of the Sun located on the front, which represents the present. The third is the Black Sun on the back, which represents the past. Of these, the third face, the Black Sun, is made of Shigaraki ware tiles, a traditional craft of Shiga Prefecture. Meanwhile, one of the printing presses that supported Japanese publishing during the Meiji era was Toshaban (so-called Gariban). It was invented by Shinjiro Horii and his son from Higashiomi City and was a great invention in publishing technology at that time. The invention of this Gariban was inspired by a printing press called Edison's Mimeograph, which was released at the Chicago World's Fair (in U.S.A.) in 1893.

A Expo is a place where new technologies and products are born, triggering greater convenience in our daily lives. Now-common convenience products and technologies were also presented at the 1970 Osaka Expo.

"Wireless" means "without telephone lines,” and is the origin of today's cell phones. 1970 Osaka Expo was not just a sample exhibit, but was actually used to make calls between people at the Expo and within Japan.

The linear motor car, which uses magnetic levitation, was presented as the vehicle of the future. The "Linear Chuo Shinkansen", now under construction, will connect Tokyo and Osaka in about an hour at a maximum speed of 500 km/h.

As the name suggests, electric cars run on electricity rather than petrol. Originally introduced as the vehicle of the future at 1970 Osaka Expo, they were used as taxis for visitors.

Moving walkways are very convenient when travelling long distances. They are now found in many places, including airports, and were introduced at 1970 Osaka Expo.

Canned coffee itself had been produced before the Osaka Expo. However, it was not seen here and there at that time, and it is said that it became popular because of the Osaka Expo.

The theme of 2025 Osaka-Kansai Expo is "Designing Future Society for Our Lives".
This theme is based on the question, "What is a happy way of life for everyone in the world?" and to come up with ideas and solutions for "Future society that all life shine".
