In 2016, the population aged 65 and over accounted for 27.3% of the total population. This figure will exceed 30% by 2025 and continue to rise. The average life expectancy for both men and women has already surpassed 80 years in 2015 (※1). In the future Japanese society, people must plan their lives assuming they will live into their 70s and beyond.
The role of digital technology in enhancing the quality of this extended senior life is expected to grow significantly. However, many digital services, primarily centered around smartphones, are evaluated from a younger generation's perspective, with little discussion of their actual contribution to senior life. Is digital technology truly making seniors happier?

What do seniors seek from digital technology, and what do they gain?
When considering digital technology and senior happiness, Dentsu Inc. Media Innovation Lab focused on seniors' "pleasures" and "worries." While broadly termed "seniors," their circumstances vary greatly—economic status, health, family ties, social networks. Rather than demographic attributes, we examined how seniors with diverse daily "pleasures" and "worries" use digital services based on their motivations (motivation), and what psychological and behavioral changes (activation) result. This article clarifies the contribution of digital services to senior life based on this experiential research.
Facebook: Enjoying Hobbies and Connecting with Friends
Figure 1 summarizes Facebook usage among seniors who "enjoy interacting with others through hobbies" (※2) as part of their daily pleasures. It compares the scores of these seniors with those who do not share this hobby, examining three perspectives: usage rate, motivation for use, and psychological/behavioral changes (activation) resulting from use.
※2 Seniors who primarily responded that they feel joy in daily life during activities such as "interacting with people who share the same hobbies or sports," "immersing themselves in hobbies or sports," or "showing others the results of their hobbies or sports."

and eight types of "activation factors" derived from factor analysis.
Seniors who enjoy interacting with others through hobbies use Facebook more frequently than those who do not. As a result of this usage, it leads to increased activation in various areas such as communication, taking new steps, and self-expression.
For seniors who enjoy interacting with others through hobbies, Facebook functions as a fun social space, much like student club activities. For seniors who may become less outgoing or more withdrawn with age, the benefits of such social media are particularly significant.
LINE: Connecting with Family to Ease Anxiety
Digital technology also contributes to seniors facing challenges. Figure 2 summarizes LINE usage among seniors who "feel anxious about their physical health" (※3). Seniors with health concerns show a high LINE usage rate. Their motivation for using it strongly reflects a desire for family and friend interaction, and they report feeling that family communication has actually increased. By providing a means for constant communication with family, LINE appears to alleviate seniors' anxieties.
※3 Seniors who primarily responded that they are troubled by items such as "feeling physical decline recently," "feeling memory decline," or "feeling unwell even though not sick" in daily life.

Households consisting solely of individuals living alone or married couples accounted for less than 30% combined in 1980, but this figure increased to 55.4% by 2014 (※4). For many seniors, family members are not necessarily always present.

Unlike phone calls, instant messengers don't unilaterally tie up the other person. For seniors who don't want to burden their families but still wish to stay emotionally connected, the pacing of instant messengers might be just right.
Creating a Place for Oneself on Instagram
Figure 3 examines Instagram usage among seniors (※5) who struggle with feeling they have "no place to belong" in their lives. Seniors with such concerns use Instagram more frequently. They also use it with motivations distinct from Facebook or LINE, such as wanting to feel happy or stay young. As a result of their usage, positive psychological changes (feeling happy), taking new steps, and self-expression (activation) increase. Through Instagram, we can see them opening up new worlds.

When friends and acquaintances react to photos you've carefully crafted yourself with likes or comments. Instagram photo posts offer the joy of being affirmed. In the same survey, when seniors were asked why they give "likes," the highest percentage cited "to compliment the other person" on Instagram (※6). It seems a surprisingly large number of seniors find encouragement in positive reactions to their posted photos. For some seniors, social media may be an irreplaceable source that connects to their sense of purpose.

Focusing on seniors' joys and concerns reveals the positive impact social media can have on them. These aspects connect to challenges in an aging society, such as seniors' social interactions, family relationships, and sense of purpose.
As Japan's aging population continues to grow, the role of digital technology will remain a critical question.
Digital technology isn't just for young people. We look forward to the development of digital services that engage with seniors.
