On the 6th, the government began construction work to create a new seawall in response to the relocation of the U.S. military base Futenma in Okinawa to Henoko, Nago City.

In footage taken at the scene from an NHK helicopter around 1:30 p.m., it can be seen that stones are placed in a net suspended by a crane truck, moved close to the sea, and then dropped into the sea using heavy machinery. Governor Tamaki of Okinawa Prefecture, who opposes the relocation, has called on the government to halt construction.
