界隈
Meaning: Community, scene, niche — the circle of people who share a specific interest or belong to a particular fandom.
界隈 originally means 'neighbourhood' or 'vicinity,' but as slang it refers to online and offline communities centred around a shared interest. Every niche has its 界隈: コスプレ界隈 (cosplay community), VTuber界隈 (VTuber scene), 美容界隈 (beauty community). It implies insider knowledge and shared culture — being in a 界隈 means you know the references, the drama, and the unwritten rules.
