Many people still keep their old phones filled with fond memories. But, when batteries of feature phones are left for long periods of time, they are fully discharged and no longer usable. Pictures or videos inside phones will not be refreshed. Therefore, we come up with the idea to realize restarting mobile phones and create valuable experience.

When treasured memories were refreshed, the moment was like opening a time capsule. Refreshed data included voice mails or pictures of deceased family members and pet animals, videos of their children when they were little and some embarrassing texts before the wedding day. The campaign was filled with smiles and happy tears. The campaign was designed inside KDDI in 2016. It took 6 months to prepare equipment ”tester” to revive mobile phones. Later, au shops were informed that the in-store campaign would take place nationwide. It was launched from August 2017. Events were held in major cities: Nagoya, Sendai, and Fukuoka in Japan. In 2018, it will be held in Tokyo, Osaka, Hokkaido and Okinawa. The number of participants of each venue was about 200.
