Also with the spread of e-commerce and teleworking many activities appear "less active" now.
Shopping used to be entertainment back in the days. Now many people buy everything from groceries to clothes from the "comfort" of their chair in front of PC, or smartphone. many brick&mortar shops went bust.
People used to read paper newspapers not digital ones. And i mean buying a paper in a newspaper kiosk, holding it proudly in front of you for all to see, turning the pages with an ear-pleasing sound. It feels more active than just swiping newsreels on smartphone isn`t it?
Can`t say about Japan but in some countries telephone booths were still used by general population 20 years ago. And lining to a telephone booth to make a call appears like a bustling activity, compared to making mobile phone call.
Also with advent of digital cameras, there is no more need to go to photo studios to develop films...
I could probably go on and on.
