Home affordability decreased for the average income earner in Japan this year. This is according to a data released by Tokyo Kantei, which shows that the nationwide income multiple (compared to the average price of a home) increased in 2019. As can be expected, major urban centers like Tokyo, Yokohama, and Kyoto are the least affordable places to buy a home in Japan, while the most affordable are in rural prefectures.
The “income multiple” is the ratio of the average price of a home to the average annual income. The lower the multiple, the more affordable it is for the average income-earner to buy a home. The increase in the income multiple last year means that it was less affordable for the average worker to buy a home than in 2018.
In 2019, the national “income multiple” was 8.09 for a newly built apartment, which means that the average price of a new apartment nationwide was on average 8.09 times the average annual income.
Based on Tokyo Kantei data, nationwide, the average annual salary in 2019 was ¥4.48 million ($41,000) and the average price of a new 70-sqm apartment was ¥36.23 million yen ($332,000). In 2018, the national income multiple was 7.81.
In 2019, the income multiple increased in 27 of Japan’s 47 prefectures.
Most and Least Affordable
The three most affordable prefectures to buy a new apartment this year were (income multiple in parentheses):
- Kagawa (5.44)
- Yamaguchi (5.64)
- Nagano (5.90)
The three least affordable prefectures to buy a home were (income multiple in parentheses).
- Tokyo (13.3)
- Kyoto (11.95)
- Kanagawa (11.10)
A Median Multiple Above 4.1 Means Housing is “Seriously Unaffordable”
The Median Multiple has been recommended by the World Bank and the United Nations to compare affordability in urban housing markets across countries.
It is calculated by dividing the median house price in a given market by gross annual median household income.
Note that this methodology differs from Tokyo Kantei’s, which uses average prices and incomes, but it is still instructive to compare the two multiples to get a general idea of just how affordable or unaffordable houses are in Japan.
According to the Demographia International Housing Affordability Survey,
— A Median Multiple of 5.1 and over indicates a market that is “severely unaffordable”
— A Median Multiple of 4.1 to 5.0 indicates a market that is “seriously unaffordable”
— A Median Multiple of 3.1 to 4.0 indicates a market that is “moderately unaffordable”
— A Median Multiple of 3.0 and under indicate a market that is “affordable”
Based on the Median Multiple method, buying a new apartment was “seriously unaffordable” in 45 of Japan’s 47 prefectures, for which there was sufficient data to calculate a multiple. Not enough data was available for Akita and Fukui prefectures.
