Short Stories about the Museum
Time Capsule
In the courtyard of the museum, you can see the main shell of the time capsule that Panasonic displayed at the 1970 Japan World Exposition (EXPO '70), which was held in Japan. Inside the museum building, you will find a display booth that presents the theme of “EXPO '70 and Time Capsules” using films and printed materials.

Time capsules like this were prepared by Panasonic and The Mainichi Newspapers to commemorate EXPO' 70 in Japan, in the hope of transmitting aspects of the present culture to those living in the future, some five thousand years on. With this aim of preserving the culture as of 1970 over a five thousand-year period for the interest of future generations, 2,098 thoughtfully selected articles and archives were placed in capsules. Two capsules were buried in a park area in front of Osaka Castle; one at a depth of 10 meters for opening every 100 years, and the other at a depth of 15 meters for opening after 5,000 years.

The first of these time capsules was actually opened early on March 15, 2000, just 30 years from the burial date. Of the 2,098 items in the capsule, 173 were inspected. Even though bacteria in some containers were found to be dead, most items had retained their original performance and states. Products such as a rice cooker and a TV set functioned normally, and testing of plant seeds found that they were still capable of germinating. Following these inspection activities, the time capsule was reburied on November 23 of the same year.

On March 15, 2003, three seedlings of Japanese red pine that grew from seeds extracted from the time capsule during the inspection were planted in the Expo Memorial Park as “trees from the time capsule.” These trees tell people of the dignity of life. As living witnesses of EXPO' 70, these strong-growing pine trees evoke in us the desire to sustain and expand the dreams contained in the time capsules.

The three young pine trees represent three wishes: a wish for the germination of life, a wish for the Earth, and a wish for carrying dreams into the future.

Two young Japanese red pine trees of the same origin were planted in the grounds of the Konosuke Matsushita Museum on March 14, 2005.
