Gentrification, often characterised by an influx of new residents who displace established locals, has impacted cities across the world and is accelerated by the growth of global capital and the development of neoliberal governments. Artists can counter the process by using their art to promote justice and community development. This paper explores the influence of artists on the community of Baika-Shikanjima, an inner-city area of Osaka, where many creative individuals have aggregated for more than a decade. At present, the area seems to be untouched by gentrification. The findings of this field study indicate that most artists earn an income through other part-time jobs or by managing small businesses. Despite their meagre earnings, these artists live comfortably thanks to affordable housing, products, and services in the area. The artists exhibit or perform their work for other artists, tourists, and residents. The audience members or participants interact with each other during these performances. The study suggests that artists in this area counter the course of gentrification simply by pursuing their activities and rooting them in the community and daily life of the area. Furthermore, their activities seem to create public spaces through which marginalised groups and individuals are provided the opportunity to engage with other residents. The artists could be regarded as outsiders or authentic tourists who integrate into the local community. Although globalisation accelerates gentrification in many areas of Osaka city, this case study shows that a more sustainable inner-city development is possible if artists are involved in community life.
