The Photo Booth Corner in Japan Has a Sign About You. It Isn't What You'll Assume.

Why this phrase

Decode the sign 「男性のみでのご利用はお断りしております」, i.e. men-only groups, we have to decline. The reason is not a joke about men: the purikura corner is a small, curtained space used mostly by teenage girls, and arcades adopted the rule as 防犯 after real problems with voyeuristic filming and customers being approached. Operators say so explicitly and add that there is no discriminatory intent. It's a safety rule for the customers inside, not a verdict on you, and a mixed group is normally admitted. Then the phrase for checking any rule politely: 「男性だけでも大丈夫ですか？」, which transfers straight to 子供でも／予約なしでも／カードでも. ACCURACY GUARD from the Japanese verifier: this is per-store policy, not law or an industry rule, and a few purikura shops are women-only outright, so say a mixed group is NORMALLY fine, never 'always'. TONE GUARD, non-negotiable: warm and unbothered. The rule is actively debated inside Japan, so do not editorialize in either direction. Never 'Japan bans men', never outrage, never a grievance beat. The line to land is 'it's not about you personally, and it takes ten seconds to ask'.
