Correction to: 'Violence in the prehistoric period of Japan: the spatio-temporal pattern of skeletal evidence for violence in the Jomon period'.

After publication of our article, we found that Kamikuroiwa Iwakage site was wrongly categorized to the Early Jomon phase and counted doubly in the electronic supplementary material; however, the site should belong to the Initial phase. Also, the number of individuals at some sites were slightly wrong. We have therefore modified figure 1, table 1 and the electronic supplementary material (see also Dryad: http://dx.doi.org/10.5061/dryad.60d18). Following these modifications, some parts of the main text in §3. Results and §4. Discussion and conclusion have also been corrected as follows (corrected expressions are emphasized in bold). Note that these corrections do not affect our main conclusion at all.
