**Appendix D**

Each respondent indicated the importance of the 58 national goals (combinations of six domains and 11 SD criteria) in the survey using a 10-point scale. We applied cluster analysis to the responses of the importance to check which domains or SD criteria tend to fall in the same cluster, i.e., which domains or criteria are relatively similar. As shown in Figure A1, many clusters tended to include the same domains rather than the same criteria. The total number of the items (combinations) with the same domains in the same clusters was 22, and the number of the items with the same SD criteria was 12 for Japan. These numbers were 26 and 25 for South Korea, 29 and 14 for Thailand, and 25 and 16 for Vietnam. For the total for all four countries, these numbers were 102 and 67.

**Figure A1.** An example result of a cluster analysis for the standardized current importance of the 58 combinations of domains and SD criteria (Japanese respondents only). The items on the left of the dendrogram indicate the combinations. Boxes around the combinations indicate the clusters determined at the red line. The six domains are A: economy, B: ecosystem, C: education, D: energy, E: Food, and F: health. The 11 SD criteria are 1: accessibility, 2: capability, 3: convenience, 4 efficiency, 5 environmental capacity, 6: inclusiveness, 7: resilience & stability, 8: security, 9: self-sufficiency, 10: social justice, and 11: variety of choice.
