Cleanest cities in Asia

Overview

Kyoto tops our ranking of cleanest cities in asia at 8.0/10, just ahead of Singapore and Sapporo. "Cleanest cities in Asia" is one of the most searched relocation questions we track — and most articles answering it are written from a single traveler's memory, not from consistent data across cities. Ranked purely on our environment score: air quality and pollution levels. Limiting the 303-city database to Asia alone and sorting strictly by cleanest gives a regional read that a worldwide ranking would otherwise blur. It's worth noting the spread: scores here range from 8.0 down to 2.0, so position #1 and position #76 aren't just marginally different — they represent genuinely different day-to-day experiences. The gap between the #1 and #3 spots is often smaller than it looks: a 0.3-point difference in an aggregate score can come from a single criterion, so it's worth opening a city's full scorecard rather than trusting the headline number alone. This is deliberately narrow: a regional, single-criterion cut for people who've already ruled out other continents and want to compare like-for-like. Below is the complete list with every underlying score, plus links through to a full breakdown for each city.
