Post-COVID, inbound demand to Japan has fully recovered, and the booming Airbnb business has drawn many people to consider it as a side job. Tetsuya Tsuji, who previously achieved annual revenue of about 100 million yen in the Airbnb business and now focuses on Airbnb operation outsourcing, and who authored a book on the path to wealth through side businesses, notes that Airbnb is the strongest side business for white-collar workers. The article explains that Airbnb profits come not only from hosts but also benefit property owners through effective real estate use, offer guests a wonderful experience in Japan, and can contribute to local employment and community development. For those who want to run Airbnb as a side business while holding a day job, using an outsourcing operator is the best approach. Then which areas are profitable for Airbnb? As securing properties has become increasingly difficult, it is important to predefine a priority order and make quick decisions. In Tokyo’s 23 wards, the ranking is: (1) S-Class: Shibuya, Minato, Shinjuku, Sumida, Taito; (2) A-Class: Shinagawa, Katsushika, Bunkyo, Toshima; (3) B-Class: Kita, Meguro, Edogawa, Setagaya, Nakano, Ota. Notably, Chiyoda and Chuo, which host major commercial hubs, are not S-Class despite their popularity in real estate investment, due to ward-specific rules that hinder Airbnb operations; the same applies to Arakawa and Koto, which are also challenging because of administrative hurdles. Of course, not every S, A, or B class area will be profitable; a profitable Airbnb property should be within a 15 minute walk from the nearest station, since proximity to the station is a key factor in real estate value. How, then, can one attract inbound travelers to a property in Tokyo 23 wards? The article explains that most inbound guests arrive and depart via Narita Airport, so aligning inbound strategy with this flow is essential, and ignoring the inbound route can jeopardize profitability. The section emphasizes considering inbound flows when repurposing a property for Airbnb and being mindful of local regulations when planning operations.
