We construct a dataset of the maturity structure of Japanese government bonds and bond yields and structurally estimate a preferred-habitat term structure model for fiscal years 1975 and 2020. The model incorporates a stochastic trend common to the short rate and the maturity-composition factor, allowing changes in the long-run mean of the short rate. The study finds that a decrease in the maturity-composition factor, which is characterized by an increase in the share of short-term remaining maturity in Japan, has compressed the long-term bond yield in a persistently low interest rate environment, particularly over the past decade.
