Tokyo, Japan

Prague, Czechia
Income tax is a flat 15% up to a high threshold and 23% above it, with social and health contributions deducted on top. Rents have climbed quickly in the centre, but public transport and everyday costs remain low, so take-home pay stretches further than in western Europe.
