East Asia's twin tech-mega-city capitals — both among the world's safest. The choice is K-pop + spicy food (Seoul) vs anime + reserved-polish (Tokyo).
Seoul scores 88/100 on Kakapo's safety index; Tokyo scores 92. Both are among the world's safest mega-cities. The 4-point gap reflects Tokyo's slightly better baseline + the Kabukicho-pattern is real in Tokyo while Seoul's nightlife scene is less scam-targeted. Both visited by millions safely each year.
The choice is rarely safety — it's K-culture + Korean food (Seoul) vs Japanese polish + tradition + scale (Tokyo).

The four sub-scores recalculate automatically as sources refresh, typically within 24 hours of a new advisory or incident report. Full per-source weighting: https://kakapo.travel/about/methodology.
