Japan Yield Curve, Across Half a Century

Field notes

The visualization uses constant-maturity Japanese government bond yields in percent and pairs them with the BOJ overnight call rate. Its controls support hover or keyboard inspection, comparison of up to three pinned eras, table view, and CSV export. The accompanying explanation records the changing yield-curve-control references, including the ±0.25% allowance introduced in March 2021 and the ±0.5% widening in December 2022. The page attributes its data to Japan's MOF and BOJ.
