In Japan, the “pets vs. kids” comparison isn’t a metaphor — it’s a real snapshot of demographics.
Official government statistics put the number of children under 15 at 14.01 million (as of April 1, 2024), the lowest on record in the modern series and part of a decline that’s been continuing for decades.
At the same time, industry tracking shows there were roughly 15.9 million dogs and cats combined — about 6.844 million dogs and 9.069 million cats — meaning household pets (just cats + dogs) outnumber young children.
This gap says a lot about how life is changing: later marriage, fewer births, smaller households, and a society where companionship often takes forms that fit modern schedules, apartments, and budgets.
It’s also why entire markets keep expanding around pet health, premium food, grooming, and services — because when a country has fewer kids, “family spending” doesn’t disappear; it shifts.
