In addition to vacant properties, the non-statutory tax will also target vacation homes and unoccupied secondary residences, with factors such as the property's value and location taken into consideration when calculating the amount to be taxed. Levied on top of property tax, the addition is expected to increase the tax burden on owners by around 50%. Properties of low value and traditional townhouses — known as machiya and popular among foreign tourists — will be exempt. The Kyoto municipal government estimates that the tax on a vacant 40-year-old apartment, 60 square meters in size and struggling to be sold, would be around ¥24,000 ($181) a year. Meanwhile, a five-year-old condominium on the top floor of a central high-rise building, 100 square meters in size and used several times a year as a vacation home, would attract an annual tax bill of roughly ¥939,000.
