In January, 1968, two Japanese companies, Panasonic Corporation and The Mainichi Newspapers, agreed to undertake a joint time capsule project in celebration of the Japan World Exposition 1970: EXPO ’70. After three years of planning, research and construction, two time capsules identical in every detail were buried adjacent to Osaka Castle. The lower capsule will remain buried for 5,000 years; the upper capsule will be opened for the first time in the year 2,000 and every 100 years thereafter.
The purpose of the project is to send forward in time a visual, aural and documentary record of life in the year 1970 AD. The scale of the project and the size of the capsules is unprecedented: each capsule contains 2,098 objects and recorded items representing the achievements of our civilization and the everyday experience of the Japanese people. The heritage left by our ancient and more recent ancestors is recorded through art, Iiterature and music. Even the ideals and aspirations of people today are expressed in written and recorded messages.
In the construction of the capsules and preparation of their contents nothing was left to chance. Every item was treated with the most advanced preservation techniques known to man at this time; some preservation techniques were devised specially for this project. The Japanese public, together with scientists and scholars from all over the world, took part in the selection process.
This book records why how and where the capsules were buried. It also contains a complete list of the contents and an extensive index to items and words that are Japanese by usage and tradition. It is dedicated jointly to our descendants and to the people of the present having the vision to see beyond their own lifetime into the world of the future.
