Language played a pivotal role as both a tool and a symbol of European influence in Asia. European languages became the medium of administration, education, and trade in the colonies, which helped to solidify European dominance. For instance, Dutch was used in administrative and legal matters in the Dutch East Indies, while English became prevalent in British-held territories like India. These languages often became lingua francas, facilitating communication between different Asian ethnic groups and with Europeans. However, this linguistic imposition also led to the decline of local languages in formal and elite domains, which had long-term implications for cultural and linguistic diversity in Asia.

European colonial activities were frequently accompanied by missionary efforts to spread Christianity. Missionaries often arrived with or followed traders and colonists, capitalising on the new European-established infrastructures and trade networks to disseminate their religious beliefs. In areas like the Philippines and Goa, the spread of Christianity was extensive, with conversions being encouraged by colonial authorities and missionaries alike. The establishment of churches, schools, and mission settlements facilitated the spread of Christianity. However, resistance to conversion efforts in places like Japan and China sometimes led to persecution of Christians and restrictions on missionary activities.

European expeditions had a significant impact on Asian cuisine and food production. The introduction of new crops from the Americas, such as chillies, tomatoes, and potatoes, revolutionised Asian agriculture and diets. These crops were integrated into local cuisines, creating new dishes and culinary practices. Furthermore, the demand for cash crops by Europeans led to changes in agricultural production; for example, large swathes of land were converted into spice plantations in the Moluccas and tea plantations in India. These changes had a lasting effect on food production patterns and dietary habits in Asia.

The arrival of Europeans had a marked influence on urban development and architecture in Asian cities. European powers established colonial cities such as Batavia (Jakarta) by the Dutch and Bombay (Mumbai) by the British, which were designed according to European urban planning principles. These cities featured wide boulevards, public squares, and fortifications. The architecture within these urban centres often reflected European styles, with the introduction of Baroque, Neoclassical, and later, Victorian architectural elements. These European styles were sometimes blended with local architectural traditions, giving rise to distinctive hybrid forms. This architectural syncretism is evident in landmarks such as the Portuguese churches in Goa and the British colonial buildings in Kolkata.

The establishment of European colonies in Asia often resulted in the imposition of European legal systems, which fundamentally altered traditional practices and governance. Europeans introduced their own codified laws, replacing various customary laws that had been unwritten but deeply ingrained in local cultures. This led to significant changes in property rights, trade regulations, and criminal justice. For instance, the Dutch implemented Roman-Dutch law in their colonies, which persists in Sri Lanka. These changes often privileged European settlers and traders at the expense of local populations and were sometimes resisted or only partially adopted.
