Weekly magazine Nature is delivered by Japan Post’s "Yu-mail" service.
From October 2021, due to the revision of the Postal Law, Saturday delivery of postal items will be suspended and the delivery time will gradually be moved back by about a day.
There is a possibility that the delivery of Nature will be delayed by a few days. Thank you for your understanding.
