Noun or suru-verb meaning 'localization' or 'to localize'; 限局性 is the adjectival form describing the state of being localized.
Compound of 限 (gen, 'limit') + 局 (kyoku, 'area, bureau') + 性 (sei, 'nature, -ity'). The exact derivation is uncertain, but the term is used in medical contexts to mean 'localized' or 'circumscribed'.
