Airbnb's strategy to wipe out the underground housing rental market, referred to as "yami minpaku", in Japan meets with considerable success. The company has managed to bring a substantial portion of these unregulated businesses into the legal framework. This development not only bolsters Airbnb's dominance in Japan's vacation rental market but also promotes legitimacy and trust among local and international tourists.

In Japan, "yami minpaku" has been a controversial topic amidst concerns related to safety, regulation, and respect for local community standards. The government, as well as citizens, have long been concerned about these hidden rentals. Airbnb's move to eliminate these shady businesses is considered a progressive step toward enhancing Japan's hospitality sector.

In the US and EU, a similar issue would be the black market or "under the table" short-term rentals. These countries also grapple with balancing a booming sharing economy and protecting residents' rights and community standards. However, Airbnb's success in Japan sets a unique, proactive example in dealing with such unregulated businesses.
