Japanese adults are fueling a capsule toy craze that has pushed the gacha gacha market to ¥196bn ($1.2bn) last year, more than quadrupling since 2021. The trend, driven by "kidults" who refuse to abandon childhood hobbies, defies Japan's declining birth rate and targets younger women seeking personal escapes through collectible toys priced at ¥300-400 each.

The phenomenon coincides with specialist megastores proliferating in vacant retail spaces left by pandemic closures, with roughly 1,400 capsule stores now operating nationwide. T-Arts Company, the second-largest player, credits the cultural shift to changing societal expectations about adulthood. Social media has broken down the psychological barrier that once confined these toys to children.

However, rising plastic costs from Middle East oil shocks threaten the industry, as prices can only increase in ¥100 increments, potentially forcing 20-33% price hikes. Operators are also eyeing overseas expansion, particularly the US market, though they face challenges adapting the coin-fed model to cashless societies and competing with claw machine prizes.

The sector plans to sustain growth through rapid product development, releasing approximately 700 new toys monthly, though Japan may be nearing saturation for new store openings. Industry leaders believe the kidult movement reflects broader acceptance of character goods as individual expression rather than childish indulgence.
