In the north-eastern suburbs of Tokyo, a group of elderly residents is attending a beginner's smartphone class at a public facility in Nerima. Led by Yasushi Nishioka, a retired programmer, the class aims to help participants, mostly in their 70s, navigate the complexities of smartphones as Japan phases out its 3G network. With the closure affecting half a million users and various devices, seniors are motivated to learn to avoid digital isolation. Participants express intimidation by their devices but are eager to master functions like making calls, using apps, and managing security concerns. Nishioka emphasizes the importance of practice and encourages them to explore features such as cashless payments and social media. As they adapt, many seniors find that smartphones enhance their lives by enabling ticket reservations, communication, and access to information.
