Japan has often been described as a homogeneous and unique society. For centuries, the discourse of Japanese exceptionalism and the myth of mono-ethnicity have been inculcated by the Japanese leadership in its population. Therefore, when significant numbers of Asian migrants arrived in Japan in the late 1980s, their presence became a potential threat to the concept of 'Japanese homogeneity.' The arrival of foreigners in a community based on the myth of homogeneity has given rise to episodes of discrimination and social exclusion. However, the present study's hypothesis is that their coming to Japan represented a great opportunity. The article's objective is to analyse this migration flow as a phenomenon that has led to, among other things, the emergence of new creative spaces where it is possible to strengthen the sense of belonging to an inclusive urban community rather than fragmenting it. The research question, which is the thread running through this paper, leads to the question of how newcomers, in particular, have made this peaceful coexistence possible. To answer this question, the article first analyses the link between migration and urban creativity; it then explores the theme of urban rituals as events generating creative, community, and inclusive spaces. Finally, the 'Festa Samba' parade in Hamamatsu, a city known for the high number of nikkeijin from Brazil and Peru, represents the empirical case study aimed at testing the starting hypothesis.
