In this list, we have compiled the smart cities in Asia that have shared out data publicly in an aggregated open data portal. For the scope of this list, we have included only the open data portals of cities in a country and not the country's national open data portal, with the exception of Singapore as a city-state.
In general, we note that more cities in North Asia have embarked on city-level open data initiatives compared to cities in South Asia. The countries with the most city-level open data portals in Asia are Japan (14+ city portals), South Korea (9+ city portals) and Taiwan (7+ city portals).

Some of the notable well-designed city open data portals with rich datasets include:
