概要	This study extracts topic-specific collocations from J-TOCC2 and examines their usefulness for Japanese language education. Using long-unit lemma data, the authors extracted noun + case-marking particle + verb trigrams from 16 SDG-related topics and identified topic-specific candidates using log-likelihood ratios. The analysis found 296 candidate collocations, including expressions such as fūdorosu o herasu “reduce food loss” and infura ga totonou “infrastructure is developed.” A pedagogical evaluation of 89 items from the first five topics showed that about half were high-priority expressions for explicit instruction. The findings suggest that J-TOCC2 can support syllabus and materials development through empirically selected collocations.
