Okay, no problem. Let's talk about this topic, and I'll explain it clearly in plain language.

How Exactly Does Japan's "Aging and Shrinking" Population Impact Companies' Efforts to Gain New Users?

Hi! I'm glad to chat about this with you. The question you raised really hits a sore point for Japan-based companies like LY Corporation (parent of LINE and Yahoo! JAPAN). What "population aging" and "declining birth rates" mean, in plain terms, is there are more and more elderly people and fewer and fewer young people.

The impact this has on companies trying to acquire new users isn't something that can be summed up in one sentence. Think of it like fishing in a pond.

1. Fewer "New Fish" in the Pond, Growth Hits a Wall

This is the most direct and critical point.

  • The market ceiling is here: The total number of users for any app or website can't exceed the country's total population, right? As Japan's total population starts declining, especially with a sharp drop in the number of young people (15-40 years old) who are the main consumers and internet users, it means the "pond" itself is shrinking. Where do new users come from? There simply aren't enough people. Before, maybe 1 million 18-year-olds entered the market each year; now there might be only 800,000. For companies relying on constantly acquiring new users, this cuts off the lifeblood.
  • Acquisition costs skyrocket: With fewer fish, the fishers (all the companies) have to work much harder and use better bait to catch the few remaining small fish. In other words, the cost of advertising and promotion to acquire a new user keeps getting higher. With everyone competing for a dwindling pool of young people, how could the competition not be fierce?

For LY Corporation, penetration of LINE and Yahoo! JAPAN in Japan is already extremely high – they're practically "national apps." Finding someone who hasn't used them is very difficult. Growth potential is basically tapped out.

2. The Fish in the Pond Are "Collectively Aging" and Their Tastes Are Changing

Fewer new fish isn't the whole story. The habits and needs of the older fish remaining in the pond are completely different too.

  • Products need to be "age-friendly": Young people like cool, complex, feature-rich products. But older users? They might have presbyopia (age-related farsightedness), and their fingers aren't as nimble. They need larger fonts, clear buttons, simple operation, and processes that aren't overly complicated. Flashy features become more of a burden for them. You see, LINE became popular even with seniors precisely because its core messaging function is straightforward enough.
  • Shifting demand from "entertainment" to "practicality": Young people might chase the latest social media or trendy games. But the needs of older users are more focused on:
    • Reading news/information (a core strength of Yahoo! JAPAN)
    • Connecting with family (LINE's core function)
    • Health management and medical services
    • Shopping for daily needs (but they prioritize trust, safety, and are often concerned about online scams)

So, companies can no longer attract everyone with the same product strategy as before. They have to figure out how to serve this "silver-haired" demographic well.

3. To Survive, Companies Must Change Their Playbook

Faced with this dilemma, companies like LY Corporation can't just wait it out. They have to adjust their strategies.

  • Shift from "acquisition" to "maximizing value": Since it's hard to pull in new users, the focus becomes making more money from existing users. This is called "deepening the existing market." For example, if you only use LINE for chatting, they'll try to get you to use LINE Pay for payments, read news on LINE, shop with LINE... By wrapping all your life scenarios into one super app, they increase the value per user (Average Revenue Per User - ARPU).
  • Aggressively develop the "silver economy": Since there's a large elderly user base, develop services specifically for them. This could include developing ultra-simple smart home appliances, offering online medical consultation services, creating travel products tailored for seniors, etc. This market might be tough to crack, but it has huge potential.
  • Go Overseas! Fish in a bigger pond: This is the most fundamental solution. If the Japanese market is declining, go find growth in overseas markets. This is why LINE has been so successful in places like Thailand and Taiwan. For LY Corporation, the hope for future growth significantly lies not within Japan, but overseas.

In Summary:

Simply put, the impact of Japan's population problem on companies' user growth is twofold:

  1. Quantitatively: The source of new users is drying up, the market size is peaking or even shrinking, making growth extremely difficult.
  2. Qualitatively: The average user age is increasing; demand is shifting from trendy and entertainment-focused to simple, practical, and safe, forcing companies to adjust their product and service direction.

It's like a restaurant chain that used to expand by constantly opening new locations. Now it finds there's no space left for new outlets in the city, and the customers' tastes have shifted from preferring fried food to wanting lighter, healthier options. Then the restaurant has two choices: 1. Renovate the old locations, introduce a healthy menu, and get existing customers to spend more (deepen market penetration); or 2. Open new locations in the next city over (go overseas).

For giants like LY Corporation, they need to pursue both paths.
