Defense Minister Shinjiro Koizumi Visits Okinawa to Address Base Burden and Bolster Regional Security

Introduction

Japanese Defense Minister Shinjiro Koizumi recently concluded a visit to Okinawa Prefecture, engaging in discussions with local leaders and U.S. military officials. The visit, which included meetings on Wednesday and Thursday, January 7 and 8, 2026, aimed to foster local understanding regarding the ongoing relocation of U.S. military facilities and to address the burden placed on the prefecture by hosting a significant portion of U.S. forces. It was Koizumi's second visit to Okinawa since assuming the defense portfolio, following an earlier trip to the Sakishima Islands in November 2025.

Futenma Relocation and Local Concerns

A central theme of Minister Koizumi's discussions was the contentious relocation of the U.S. Marine Corps' Futenma Air Station from a densely populated area in Ginowan to the less populated Henoko coastal area in Nago. During a meeting in Naha with Nago Mayor Taketoyo Toguchi, Koizumi emphasized the government's commitment to minimizing the impact on residents, stating, 'We will persistently urge the U.S. side to address issues such as noise from U.S. military aircraft and strive to minimize the impact on residents.' Mayor Toguchi, however, stressed the importance of dispelling residents' concerns and protecting their living environment. Okinawa Governor Denny Tamaki reiterated his call for the central government to abandon the relocation plan, despite Koizumi's assertion that construction work would 'proceed in a tangible way.'

Strengthening Japan-U.S. Alliance and Regional Defense

Beyond base relocation, Minister Koizumi's visit underscored efforts to strengthen the deterrence and response capabilities of the Japan-U.S. alliance. He met with Lt. Gen. Roger Turner, the top U.S. military official in Okinawa and Commanding General of the U.S. Marine Corps' III Marine Expeditionary Force. Koizumi highlighted that 'local cooperation and understanding are necessary to maintain and strengthen the deterrence and response capabilities of the Japan-U.S. alliance,' and requested measures to prevent incidents and accidents involving U.S. military personnel. Turner affirmed the U.S. military's desire to be 'good neighbors' and contribute to Japan's defense.

The visit also addressed the increasing importance of defending Japan's southwestern Nansei Islands, particularly in light of China's growing military activities in the region. Koizumi stated that strengthening Japan's defense system in these regions is an 'urgent task' given the severe security environment. He also visited Yonaguni Island in November 2025, where he discussed the deployment of missile units, asserting that such deployments can reduce the risk of attacks on Japan.

Local Engagement and Political Context

Minister Koizumi's engagement with local communities is seen as crucial for gaining support for national defense initiatives. He prioritizes reducing the burden on the local community, believing it essential for strengthening the defense of the Nansei Islands. The timing of the visit also coincides with the upcoming Nago mayoral election, with the announcement scheduled for January 18 and voting on January 25, 2026. This suggests an effort to demonstrate support for the local community ahead of the election. During his visit, Koizumi was also scheduled to meet with other local leaders, including Naha Mayor Satoru Chinen and Ginowan Mayor Atsushi Sakima.
