Minpaku troubles are mounting, triggering tougher regulations across Japan. While rules tightening on licensing and residency visa requirements have been introduced, experts warn that illegal, unregistered minpaku may still be increasing and residents' living environments could worsen. In Tokyo's Toshima Ward, complaints about noise and garbage linked to minpaku rose, prompting proposed rules to shorten operating days and bar new units in about 70% of the area, to be applied from December 2026. Around the country, other localities such as Karuizawa in Nagano and Osaka City are tightening policies as authorities warn that illegal minpaku could proliferate and disrupt community life.
