Headline doesn’t match what’s in the report. It’s not just gacha; the question in the survey is inclusive of other games that offer in-game purchases (課金 in Japanese). So we’re talking about skins and boosts in MMOs, MOBAs, and shooters, hints in games like Candy Crush, etc.

The report posted here last week showed just how much MTX spending there is on PC, of which gacha is still a small part. I suspect there is a higher rate of gacha spending in Japan than there is globally (outside of China, perhaps), but I’d be surprised if gacha even made up half of the spending SMBC is reporting on here.
