The dioecious relic Cercidiphyllum japonicum is one of two species of the sole genus Cercidiphyllum (Cercidiphyllaceae). Using an Illumina platform, we sequenced its complete chloroplast genome. Our study reveals that C. japonicum have a typical cp genome of 159,854 bp in length, comprised of a large single-copy region of 88,035 bp, a small single-copy region of 30,535 bp, and two inverted repeat regions of 20,642 bp, respectively. A total of 131 genes, 84 of which are protein coding genes, 37 tRNA genes, eight rRNA genes and one pseudogenes were identified. Phylogenetic analysis indicate that C. japonicum is closely related to the species of Sinowilsonia henryi.
