The <italic>Lactococcus taiwanensis </italic>strain K_LL004 was isolated from the gut of a grasshopper (<italic>Oxya chinensis sinuosa</italic>) collected from local farm in Korea. <italic>L. taiwanensis</italic> strain K_LL004 is the functional probiotic candidate with an ability to hydrolyse plant polysaccharides. The complete genome of the <italic>L. taiwanensis</italic> strain K_LL004 contains one circular chromosome (1,995,099 bp) with a guanine + cytosine (GC) content of 38.8%. Moreover, 1,929 Protein-coding sequence, 19 rRNA genes, and 62 tRNA genes were identified based on results of annotation. <italic>L. taiwanensis </italic>strain K_LL004 has a gene, which encodes hydrolytic enzymes such as beta-glucosidase and beta-xylosidase, that hydrolyzes plant polysaccharides.
