When families think about a child's first digital device, many naturally think of a smartphone.
It is useful. It makes communication easy. It can show location, take photos, and connect a child with friends. But as a tool for learning and creating, a smartphone is not enough on its own.
According to a 2025 survey by NTT Docomo's Mobile Society Research Institute, upper-elementary school students in Japan now spend an average of 78 minutes per day on a smartphone, and smartphone ownership among sixth-graders has crossed the 50% mark for the first time.
Meanwhile, a longitudinal analysis published by Japan's Ministry of Education (MEXT) in July 2025 found that average academic scores have fallen across all subjects over the past three years, with increasing smartphone and gaming time correlated with declining study hours.
Given this backdrop, the question of which digital device to give a child is not merely a matter of preference. Smartphones and PCs differ from each other in ways that matter deeply for education.
Smartphones Are Designed for Consumption; PCs Are Designed for Creation
The user experience of a smartphone is engineered to maximise passive consumption. Infinite-scrolling feeds, short-form videos, and push notifications are all precision-tuned to keep users on-screen for as long as possible. When a child picks up a smartphone, the path of least resistance leads toward watching and receiving, not making and thinking. This is not a flaw — it is by design.
A PC works differently. A keyboard, a mouse, a large display, and a file system are all tools for producing something. Writing an essay, building a programme, editing a video, designing a game, organising a presentation — the PC presupposes active output. Its very interface demands that the user decide what to make. And that demand, repeated over time, builds habits of structured thought and creative initiative that passive screen time does not.
Keyboard Typing: A Foundational Skill
One of the most consequential differences between smartphones and PCs is how text is entered. Flick-input on a glass screen and touch-typing on a physical keyboard engage different cognitive processes and produce dramatically different outcomes in terms of writing speed, composition quality, and sustained focus.
Young adults who grew up using smartphones as their primary device routinely report struggling with PC-based workflows when they enter the workforce. The window for building keyboard fluency naturally — through play, curiosity, and creative projects — is during primary school. Letting that window close is a harder problem to fix later.
The "Making" Experience That Smartphones Cannot Provide
The greatest educational value of a PC is the depth of creative experience it enables. Writing code and watching a game come to life. Drawing a character and animating it. Researching a topic and turning it into a polished slide deck. Each of these experiences simultaneously develops logical reasoning, problem-solving, self-expression, and the intrinsic satisfaction of completing something difficult.
Some will argue that smartphone apps can do similar things. But in terms of screen area, interface affordances, and processing power, the PC is categorically superior for deep, sustained creative work. Complex programming, video editing, working with AI tools — none of these translate adequately to a four-inch touchscreen. The making experience that builds real capability simply requires a PC.
Not Against Smartphones — About Getting the Order Right
This is not an argument against smartphones. It is an argument about priorities. The problem is not that children have smartphones; it is when smartphones become the only digital experience a child has. The gap between a child who can consume digital content and a child who can create it will only widen in the AI era.
At Digital Kodomo BASE, we provide refurbished PCs free of charge to children who lack one at home, and we keep our space in Ota Ward open for any child to drop in and freely explore computers, programming, and AI. Our goal is to give every child — regardless of their family's income — access to the "making" experience that a PC uniquely provides. Whether before getting a smartphone or alongside one, every child deserves the chance to build something, not just consume.
