Which countries? Japan’s cities, except for the southern part of Osaka and the middle part of Osaka, and the subways in Osaka, were very clean, the most notable smell being fried food and the occasional old person. Chinese cities are generally quite clean, except for the occasional whiff of durian. Hanoi and HCMC don’t smell like anything because of all the pollution.
