Governor Koja Genta, who took office on September 30 after winning the September 13 election, had sought a more cooperative relationship with Tokyo, replacing the prefectural division handling opposition to the Henoko project with an office focused on accelerating the return of US military land. However, he has maintained that cooperation is conditional on advance explanations and local understanding.
On October 5, Koja read a protest letter to Lieutenant General Benjamin Watson and US Consul General Andrew Ou, stating that the recurrence of such a serious crime "leads us to conclude that U.S. military efforts regarding discipline and human rights education are completely ineffective."
Earlier, Foreign Minister Motegi Toshimitsu summoned US Ambassador George Glass, and Defense Minister Koizumi Shinjiro summoned US Forces Japan commander Lieutenant General Stephen Jost. Prime Minister Takaichi Sanae condemned the incident and demanded full investigative cooperation, tighter discipline, and effective prevention measures.
The Marine Corps has pledged cooperation with Japanese investigators.
