In an investigation into recent arson incidents in the Musashi-Koyama area of Shinagawa City, Tokyo, police have arrested six individuals, including a 31-year-old employee of a real estate company, suspected of setting fires for the purpose of land acquisition. This arson is believed to be aimed at forcing property owners who are hesitant to sell their land, given the area's rapid redevelopment and rising property values. The arrested individuals allegedly conspired to douse a residential mailbox and an apartment room in gasoline and ignite them between October and November of the previous year.

Witness accounts from local residents reveal a sense of fear and unrest following a series of fires in the neighborhood, prompting multiple fire trucks to respond and raising concerns among the community. An elderly woman noted that men in suits had begun visiting homes in the area, seemingly soliciting property acquisitions as the real estate landscape transformed with increasing development activity. One of the properties that caught fire was among those that had ongoing negotiations for sale.

As the police inquiry continues, they are examining whether the arrested employees used arson as a means to exert pressure on landowners who were not inclined to negotiate sales. Given the significant redevelopment underway near Musashi-Koyama Station, which has included the construction of high-rise condominiums and other commercial development projects, the implications of this case may highlight broader issues of ethical practices in the real estate industry and the social impact of gentrification in the area.
