Tenants in the vicinity of Osaka's Jūsan station were taken aback when they reportedly received notices advising of a threefold increase in monthly rent. Though it is unknown at this point when the rent increases are supposed to take place, these unexpected price surges have unsettled residents in the area and aroused concerns about potential gentrification processes.

In Japan, any increase in rent often draws considerable attention as it impacts an individual's cost of living substantially. Sudden and substantial rent hikes spark debates about economic disparity and highlight the potential for gentrification in rapidly evolving urban cities. Given Japan's stringent property laws, such moves additionally accentuate the need for better rent control measures.

The issue of rent control is also prevalent in both the US and EU, where landlords are often restricted to raising rents at certain rates, typically tied to inflation. In contrast, Japan lacks robust legislation to prevent landlords from drastically increasing rents, hence fueling debates around tenant rights and affordable housing.
