Chiryū-juku was the thirty-ninth of the fifty-three stations of the Tōkaidō. It is located in the present-day city of Chiryū in Aichi Prefecture, Japan. It was the westernmost post town in Mikawa Province, and was 330 kilometres from Nihonbashi, the start of the Tōkaidō, so it took approximately 10 days to for average travellers to reach.
