The complete chloroplast genome of Chionographis japonica (Willd.) Maxim. (Melanthiaceae, Liliales) was mapped using polymerase chain reaction and the Sanger method. The circular double-stranded DNA was a typical quadripartite structure consisting of two inverted repeated regions (27,397 bp), a small single copy region (18,205 bp), and a large single-copy region (81,646 bp), with a total length of 154,645 bp. The genome consisted of 137 coding genes, including 91 protein-coding genes, 38 distinct tRNA, and 8 rRNA genes. The ycf15 and ycf68 genes had several internal stop codons interpreted as pseudogenes. The inverted repeat (IR) region expanded to part of the rps3 gene in the junction between large single-copy and IRA regions in C. japonica. We designed 785 primers, of which 481 were used to map the entire chloroplast genome of C. japonica. Primers were compared with the complete chloroplast sequence of Smilax china (Smilacaceae) to identify primers that could be used for other Liliales members and whole chloroplast genome sequencing. Of the primers used for C. japonica, 398 could be used with other smaller species within the order.
