Bases and commands
Many if not most of the U.S. military bases in Japan were involved in some manner in Operation Tomodachi.
- Yokota Air Base in Fussa, western Tokyo, is the operational command center, and furthermore functions as the aviation hub due to the washout of the Sendai Airport, Miyagi by the tsunami.
- Kadena Air Base, Okinawa Prefecture is the hub of airpower in the Pacific.
- Marine Corps Air Station Futenma
- Marine Corps Air Station Iwakuni, operated as an aviation hub for many aircraft traveling to northern installations.
- Camp Fuji
- Misawa Air Base, Aomori, combined services and Japan Self-Defense Forces
- Naval Air Facility Atsugi, Kanagawa Prefecture home of CVW-5 and Fleet Air Wing 4 of the JMSDF
- Camp Zama is the home of U.S. Army Japan and I Corps (Forward)
- Sasebo Naval Base in Nagasaki Prefecture, USS Essex (LHD-2) and its Expeditionary Strike Group.
- Yokosuka Naval Base inside of Tokyo Bay, is home to the Seventh Fleet, composed of 11 warships, including USS George Washington (CV-73) and command ship USS Blue Ridge (LCC-19).
- Task Force Fuji, Camp Fuji Marines and sailors
- Camp Courtney, Okinawa, operated as the communications post between Okinawa and Japanese mainland
Col. Stephen Bissonnette, deputy commander of the 353rd SOG stated that "[T]he devastation caused by the earthquake is truly heartbreaking...As part of coordinated relief efforts, the group will work tirelessly with our Japanese counterparts and other relief organizations to help the people affected by the earthquake recover..." The US aid efforts are conducted under the direction of Japanese government or military authorities.
The United States Navy quickly responded to provide aid. Aircraft from three FLSW (Fleet logistic Support Wing) squadrons were in theatre during the earthquake at Naval Air Facility Atsugi. VR-62's C-130 delivered 127 tons of material to aid in relief efforts and VR-58's C-40 delivered 366,000 pounds of food and water and 1400 passengers. VR-52's aircrew and maintenance detachment moved Navy patrol and helicopter units directly involved with the search and rescue of survivors in addition to relocating 185 Navy personnel and dependents from the Atsugi-based Carrier Air Group Five to Guam. During this time, the Taskmasters were airborne for 19 out of 26 hours transporting personnel and humanitarian relief supplies.[full citation needed] The aircraft carrier USS Ronald Reagan (CVN-76) and its battle group were moved to the east coast of Honshu. As well as the group's own helicopters, the Ronald Reagan served as a refueling platform for Japan Self-Defense Forces helicopters. C-2 Greyhound aircraft assigned to VRC-30 and attached to CVW-14 and CVW-5 ferried over 100 tons of food, water, blankets, clothing, and medical supplies from NAF Atsugi to USS Ronald Reagan for distribution by helicopter to local sites in Japan.
Yokota Air Base was used in the aftermath of the earthquake as a landing field for commercial flights as Tokyo Narita Airport was closed. The Navy helicopters based at Naval Air Facility Atsugi and elsewhere were made available for search and rescue immediately after the tsunami, including searching off-shore debris fields and later assisted with food drops. P-3 Orion aircraft were used to do damage surveys. Amphibious landing craft and utility landing craft (LCUs) were used to deploy U.S and Japanese troops and supplies to areas where docks were damaged. Japan electrical company trucks were moved by U.S. LCUs from USS Essex (LHD-2), notably to Oshima Island.
The destroyers USS McCampbell (DDG-85) and USS Curtis Wilbur (DDG-54), which were off the Bōsō Peninsula at the time of the earthquake, and their helicopters were made available for search and rescue. The landing ships USS Essex (LHD-2) and USS Germantown (LSD-42), with the embarked 31st Marine Expeditionary Unit from Okinawa, were moved from the Sea of Japan to the east coast of Japan.
USS Tortuga (LSD-46), an amphibious dock ship, embarked two MH-53E Heavy Lift Helicopters assigned to HM-14 DET 1 stationed in Pohang South Korea. The entire DET was on board Tortuga less than 18 hours after the earthquake and tsunami hit. Tortuga transported 800 Japanese civil defense workers from Hokkaido to Honshu with 90 vehicles.[not specific enough to verify]
Military Sealift Command ships also took part in the operation by transferring relief supplies and fuel to other supporting ships. The ships that took part in the operation were USNS Carl Brashear (T-AKE 7), USNS Pecos (T-AO 197),USNS Rappahannock (T-AO 204), USNS Matthew Perry (T-AKE 9), USNS Bridge (T-AOE 10).
USNS Safeguard (T-ARS-50), which was stationed at U.S. Fleet Activities Sasebo, arrived at Hachinohe, Japan with Explosive Ordnance Disposal Mobile Unit 5 and Underwater Construction Team 2 to clear wreckage from a local commercial channel.
During the operation the 7th Fleet flew 160 search and relief sorties for 1,100 flight hours, delivered 260 tons of relief supplies, and helped clear the ports of Hachinohe, Aomori, Miyako, Iwate, and Kesennuma, Miyagi.
In total 130 aircraft, 12,510 personnel and over 16 American naval ships took part in Operation Tomodachi, including USS Ronald Reagan (CVN-76), USS Chancellorsville (CG-62), USS Cowpens (CG-63), USS Shiloh (CG-67), USS John S. McCain (DDG-56), USS Fitzgerald (DDG-62), USS McCampbell (DDG-85), USS Preble (DDG-88), USS Mustin (DDG-89), USS Germantown (LSD-42), USS Tortuga (LSD-46), USS Harpers Ferry (LSD-49), USS Essex (LHD-2), USS Blue Ridge (LCC-19), USNS Safeguard (T-ARS-50).
The US Navy dispatched aircraft carrier USS Ronald Reagan and other vessels which flew a series of helicopter operations. A spokesman for U.S. 7th Fleet naval personnel stated that monitoring equipment indicated that the warship had been exposed to radiation. Separate hand-held equipment also picked up the contamination on 17 crew members, who had participated in rescue operations. Commander Jeff Davis said that the exposure was low enough that after the crew washed with soap and water, follow-up tests were negative. Davis characterized the exposure as comparable to routine civilian activities and reiterated the US Navy's commitment to the relief operation. As a precaution, the aircraft carrier was repositioned farther offshore, away from the downwind direction of the plant and decontaminated. Several helicopters were decontaminated after returning from flights. One helicopter made a landing at Fukushima Airport after experiencing rotor icing and exposed some Australian and New Zealand search and rescue team members to low levels of radiation.
Radiation precautions were taken at U.S. bases, including USS George Washington leaving port at Yokosuka after very low levels of radiation were detected there. Part of its air complement moved to Misawa Air Base to support relief operations.
Three years after the accident, servicemen and women who were part of the operation have reported radiation-related disorders, including cancers, thyroid disease, uterine bleeding and other ailments. 51 crew members have filed a lawsuit against the Tokyo Electric Power Company, which owns the Fukushima Daiichi power plant. (Under US law, military personnel are not permitted to sue the armed forces for damages.)
United States Marine Corps facilities in Japan escaped major damage, with no reported casualties. This intact infrastructure allowed Marines from III Marine Expeditionary Force and Marine Corps Base Camp Smedley D. Butler to mobilize aid quickly.[not specific enough to verify]
Marines based at Marine Corps Air Station Futenma moved command and control teams and systems to NAF Atsugi. Eight KC-130Js from VMGR-152 and eight CH-46E and four CH-53 Super Stallions transport helicopters from HMM-265, all from MCAS Futenma, were made available to transport rescue teams and equipment, as well as provide search and rescue.
The 31st Marine Expeditionary Unit responded to Northern Japan from Malaysia and Indonesia, where the unit was conducting Theater Security Cooperation exercises. The 31st MEU delivered relief supplies to five cities, one island and one Japanese ship. More than 164,000 pounds of food and relief supplies were delivered, along with thousands of gallons of water. Elements of the 31st MEU, including Combat Logistics Battalion 31, 2nd Battalion 5th Marines went ashore on Oshima Island to deliver critical supplies and assist in debris removal.
MV Westpac Express, a civil-registered fast ferry chartered by the Marine Corps, was made available to transport equipment from Okinawa to Honshu. Westpac Express made two sorties in support of Operation Tomodachi. The ship moved 450 tons of cargo, including 7-ton trucks, fuel tankers, generators and water tanks from Okinawa to Iwakuni, Japan, arriving 15 March. On 20 March, Westpac Express loaded 226 pallets of bottled water at Pohang, ROK, off-loading at Iwakuni the next day.
Two C-17A Globemaster cargo aircraft from Joint Base Lewis-McChord were made available to transport rescue teams and equipment. A Global Hawk unmanned aerial vehicle was deployed from Guam for damage assessments.
Yokota Air Base is the hub for air operations from which cleanup crews were dispatched to clean up Sendai airport. At a Town Hall meeting, the Commander of the 374th Air Wing USAF presented an overview of joint forces operations in support of the Japanese and emphasized teamwork between various players. He stated that "we are very blessed" to be in the nation of Japan because it has a highly sophisticated set of technologies to minimize the damage but that the personnel, logistic and financing problems were formidable.
He repeatedly asserted that the situation is "eminently controllable" in part due to highly experienced personnel available for various contingencies. US military personnel stationed at the Air Base expressed interest in making cash donations – in dollars or yen – to the American Red Cross and other organizations working in the Japanese relief effort.
Several Sikorsky UH-60 Black Hawk helicopters from the U.S. Army Japan Aviation Detachment have been made available for relief efforts. A disaster assessment team from I Corps (United States) Forward departed Camp Zama and arrived in northeastern Japan on 14 March to assist in relief and humanitarian operations as well as set up a forward logistics base for supplies. A 59-member logistics team from Sagamihara General Depot helped reopen Sendai Airport.
Operation Pacific Passage
Over 7,000 family members of U.S. service members in Japan were voluntarily evacuated in March to Seattle Tacoma Airport and Travis Air Force Base in the U.S. during Operation Pacific Passage. Concerns over the uncertainty of the radiation situation and reducing the burden of supporting families while conducting relief operations and the related troop movements lead to the relocation program.
With Yokota Air Base available, US Office of Foreign Disaster Assistance sent Urban Search and Rescue California Task Force 2 and Virginia Task Force 1. Two urban search and rescue teams arrived at the pending merger with a 60 member/two-dog team from the UK. On 3/16, a RAAF C-17 Globemaster III landed on Kadena's flight line. USAF personnel assisted Royal Australian Air Force and Japan Ground Self Defense Force to load supplies and fly to mainland Japan.[not specific enough to verify]

USNS BRIDGE (T-AOE 10) arrives on scene with 2 embarked SH-60S from HSC-23.
Two US urban search and rescue teams arrived from Fairfax County, Virginia and Los Angeles County, California with a total of 140 rescuers and 14 rescue dogs. The teams merged with a 63-member search and rescue team from the UK. The combined US-UK operation deployed to the town of Sumita, Iwate to set up a base of operations. The teams performed daily search and rescue missions in the cities of Ofunato and Kamaishi for five days until departing for home.
Members of the U.S. Navy Reserve Detachment 105 were joined by six members of the Defense Threat Reduction Agency (DTRA) Liaison (LNO) and Consequence Management Advisory Team (CMAT). These two elements formed the initial core of the United States Forces Japan (USFJ) Radiological Consequence Management Team (RCMT) whose mission was to advise Lieutenant General Burton Field Commander USFJ on matters related to the nuclear fuel cycle, potential hazards, and potential mitigation of a radiological incident. DTRA Liaison and CMAT personnel were among the first U.S. personnel to visit the TEPCO response site (J-Village) located a few kilometers from the Fukushima Diachi reactor. DTRA personnel also established relationships with TEPCO engineering and management deconflicting information for the U.S. Ambassador and United States Forces Japan Commander.
HM-14 DET 1 rapidly deploys to assist in relief efforts on board USS Tortuga. The 18th Civil Engineer Squadron also arrived at Misawa Air Base for Operation Tomodachi.
14 March 2011
The Yokota Town Hall Meeting was conducted in which personnel and their families were reassured that the problems, though formidable, were manageable given the highly qualified Japanese, US, and international personnel on the scene. There was an assurance that there would be daily monitoring of radiation levels. Many of the service men and women expressed interest in making financial contributions through the Red Cross.
Members of 623d Air Control Flight, Kadena AB, Japan, callsign "Lightsword" deployed to Honshu, Japan. The Lightsword team deployed to a JASDF radar facility, to assist in the command and control of relief efforts for the airlift effort following the 2011 Tōhoku earthquake and tsunami.
15 March 2011
Work continued to re-establish a workable landing strip at Sendai Airport. Kadena AFB personnel restored minimal power at Misawa to Air Force personnel, still pending Navy power restoration. The USS George Washington was docked for maintenance in Yokosuka, about 175 miles (280 kilometers) from the plant, when instruments detected the radiation at 7 am Tuesday (6 p.m. ET Monday).
16 March 2011
Rear Admiral Wren, the Commander, US Naval Forces Japan, sent out a letter advising personnel to limit outdoor activity at Fleet Activities Yokosuka and Naval Air Facility Atsugi due to newly developing, low level radiation.
17 March 2011
The Pentagon said Thursday that it was sending more specialized aircraft to evaluate nuclear contamination at and around the Fukushima site, including a WC-135 Constant Phoenix from Offutt Air Force Base to take air samples, which aircraft had formerly been used as a sniffer with regard to North Korean nuclear weapons testing.
Carrier Air Wing-5 was relocated from NAF Atsugi to Andersen Air Force Base in Guam temporarily, what the Navy calls a "force posture adjustment" for Operation Tomodachi. The air wing's SH-60 helicopters from HS-14 and HSL-51 and C-2 Greyhound from Fleet Logistics Support Squadron 30 Det. 5 remained behind in support of the operation. As a precaution, the navy has also stopped moving its personnel to Japan as well.
23 March 2011
Navy officials halted air operations from USS Ronald Reagan temporarily on Wednesday so they could decontaminate the ship from the radiation the ship received. While the radiation did not pose any significant health risk, "it needed to go away," Cmdr. Ron Rutan, chief engineer for the Reagan.
25 March 2011
500,000 gallons of fresh water has been provided from the US Navy to support cooling efforts at the Fukushima Daiichi nuclear power plant.

US troops assisted Japanese government workers in cleaning up debris and rubble left by the tsunami.
Effect on Japan–US relations
The disaster may have brought a diplomatic opening to Japan. The support provided by the US illustrated the value of the relationship between the countries. It was commented that the level of support provided by the US will probably assuage tension over base relocation disputes between the two governments. The Yomiuri Shimbun reported that the "coordinated relief activities at the disaster sites are expected to deepen the Japan-U.S. alliance."
On 4 April 2011, Japan's minister of defense, Toshimi Kitazawa, accompanied by US ambassador to Japan John Roos, visited the Ronald Reagan to thank its crew for its assistance as part of Operation Tomodachi. Said Kitazawa, "I have never been more encouraged by and proud of the fact that the United States is our ally."
On 10 April 2011, Japan's Prime Minister, Naoto Kan, visited Camp Sendai to talk to U.S. service members. The prime minister spoke of the immediate response of the U.S. military and expressed his belief that the joint efforts between the U.S. military and the JGSDF will strengthen the bonds between the Japanese people and the United States.
A nationwide survey conducted in Japan from September to October 2011 found that an all-time high of 82 percent had friendly feelings toward the US. Japan's Foreign Ministry attributed the number to the effects of Operation Tomodachi. Similarly, the Pew Research Center showed that 85% of Japanese people had a favorable opinion of the U.S. in 2011, the highest in a decade.
