The Japanese eel (), which was listed as Endangered (EN) under the International Union for the Conservation of Nature due to the declines in its abundance, overfishing, and its narrow range distribution. To better protect this species, we described the complete mitogenome of in this study. The mitogenome is 16717bp in length and contains 13PCGs, two rRNA genes (12S rRNA and 16S rRNA), 22 tRNA genes, and a putative control region (CR) and one origin of replication on the light-strand (OL). Moreover, the 13 PCGs encode 3813 amino acids in total, all the protein-coding genes use the initiation codon ATG except COI uses GTG. Most of them have TAA or TAG as the stop codon, except COI uses AGG and two PCGs (COII and ND4) use an incomplete stop codon T. A phylogenetic tree based on the Neighbour Joining method was constructed to provide relationship within , which could be a useful basis for conservation of this species.
日本鳗鲡（），由于其数量减少、过度捕捞以及分布范围狭窄，被国际自然保护联盟列为濒危物种（EN）。为了更好地保护该物种，我们在本研究中描述了其完整的线粒体基因组。该线粒体基因组长度为16717bp，包含13个蛋白质编码基因（PCGs）、两个核糖体RNA基因（12S rRNA和16S rRNA）、22个转运RNA基因、一个假定的控制区（CR）以及轻链上的一个复制起点（OL）。此外，13个PCGs总共编码3813个氨基酸，所有蛋白质编码基因均使用起始密码子ATG，除了COI使用GTG。它们中的大多数以TAA或TAG作为终止密码子，除了COI使用AGG且两个PCGs（COII和ND4）使用不完全终止密码子T。基于邻接法构建了系统发育树以揭示其内部关系，这可为该物种的保护提供有用的依据。
