There are four key points: macro factors like population decline, low birth rates, and changes in the media environment; and micro factors such as faster/larger-capacity communications and women's increased participation in the workforce. These are phenomena affecting all Japanese people to varying degrees and are essential points for discussing this theme.
1.Population Decline
In the future Japanese society, a decrease in the total population and an increase in the number of households, primarily single-person households, are anticipated. According to estimates by the National Institute of Population and Social Security Research, Japan's total population is projected to decrease to 116.62 million by 2030. Meanwhile, the total number of households is expected to continue increasing, peaking at 53.07 million households in 2019 before declining to 49.56 million households by 2035. The phenomena of population decline and household growth are certain to significantly impact the markets for information media across all domains and the associated information devices.
2.Women's Participation in the Workforce
Supporting Women's Participation in the Workforce is one of the key policies in the New Growth Strategy proposed by the Second Abe Cabinet. It is a measure to compensate for the shortage of the productive labor force caused by the decline in the working-age population due to population decline. Going forward, as women's participation in the workforce progresses, assuming a trade-off between time spent at home and time spent working, it is expected that time spent outside the home will relatively increase, while time spent at home will decrease. Macro-economically, significant changes in the media consumption environment, centered on women, are anticipated.
3.Changes in the Media Environment
Video Research Ltd.'s MCR (Media Contact Report) shows that the time spent outside the home by male and female teenagers increased from 530 minutes in 2000 to 575 minutes in 2014, a 45-minute increase over these 15 years. The fact that 2014 reached the peak for this 15-year period indicates that younger people are spending more time outside the home and relatively less time inside (Figure 2). This medium-term macro trend undoubtedly influences media consumption both inside and outside the home. Notably, 2011 saw a temporary dip to 558 minutes, likely due to reduced outings following the earthquake disaster. However, time spent outside the home subsequently increased significantly again, confirming the long-term upward trend in time spent away from home.
Furthermore, comparing 2000 and 2014 reveals particularly large changes in media contact time among younger age groups. Internet use at home stands out, with teenagers' total internet contact time (combining PCs and mobile devices) increasing from 6.6 minutes to 45.0 minutes (Figure 3). Outside the home, a similar phenomenon is observed, with mobile internet contact time among relatively younger age groups rising from 1.0 minute to 9.0 minutes (Figure 4). Regarding information device ownership, another key point is the high smartphone ownership rate among younger age groups for both genders. Notably, smartphone ownership rates among females in their teens and early twenties are higher than those of males (Figure 5).
