The Kokubo Sosho is located on Tokyo Bay near Tokyo, Japan and is home to the Japanese Ministry of Defense and the Information Self-Defense Force. It is the final location in Tom Clancy's Splinter Cell: Chaos Theory.
The Kokubo Sosho is a large, fortified facility that houses several branches of the Japanese Self-Defense Forces. It has been home to the I-SDF since its inception and activation in 2006. Home to the offices of many high-ranking Japanese officers, including I-SDF commander Admiral Toshiro Otomo, it is the nerve center for many of the JSDF's military operations. It is heavily guarded by JSDF personnel and has some of the most sophisticated security measures of any military facility. It also hosts the offices of many American specialists who work in close cooperation with their Japanese allies on-site at the facility.
Often, the JSDF personnel stationed at the Kokubo Sosho are LTL-equipped ("Less Than Lethal") so that they may subdue any possible intruders at the facility for immediate interrogation.
At the heart of Kokubo Sosho is the War Room, located in the sub-levels of the facility. It is sealed behind thick armored doors and is tempest-hardened, sealing out any electronic intrusions committed by an enemy party. It is here that the commanders of the JSDF meet to discuss their military actions. Below Kokubo Sosho is an underwater bunker situated over one-hundred feet below the surface of Tokyo Bay, accessible via elevator shaft from the surface. This bunker is exclusively housed by the I-SDF and serves as its command center, and is home to the office of Admiral Otomo. It is heavily guarded by remote-controlled gun drones suspended from the ceilings, designed to eliminate any unauthorized individuals.
East Asia CrisisEdit
In 2007, tensions among the East Asian powers reached a boiling point after the establishment of the Information Self-Defense Force by Japan, which was viewed by the People's Republic of China and North Korea as an effort to remilitarize Japan in direct violation of the postwar constitution. In response, the United States came to Japan's defense as North Korea and China began to harass Japanese shipping lanes across the South China Sea, sending the USS Clarence E. Walsh to the region as a show of solidarity with Japan. During the crisis however, the American PMC Displace International engineered an attack on the Walsh with a North Korean anti-ship missile commandeered through the use of information warfare, and crippling the Walsh's defensive systems through the same means. The resulting destruction of the vessel accelerated tensions in the region as the U.S. and its allies accused North Korea of launching an unprovoked attack, prompting North Korea to retaliate by invading South Korea and triggering a regional war amongst the competing powers. In trying to track down those responsible, Third Echelon sent Sam Fisher to Japan to determine Displace's intent, and discovered that its CEO Douglas Shetland had conspired with the Japanese I-SDF to ignite tensions in the region in order expand their own control over East Asia. While Fisher was successful in tracking down and killing Shetland at a bathhouse in Tokyo, the I-SDF remained active and fearing that Japan was sanctioning its actions, Third Echelon sent Fisher to Kokubo Sosho to learn of their intentions.
By the time Fisher arrived at Kokubo Sosho, the JSDF personnel there had already arrested and rounded up all of the American personnel stationed there, and were holding them hostage indefinitely while they prepared to make their next move. After infiltrating the facility and bypassing the guards, Fisher spoke directly to the hostages, who were unharmed and informed Fisher that an emergency meeting was to take place in the War Room. Fisher proceeded to the sub-levels and infiltrated the War Room's perimeter for the short time it had been opened, and due to the tempest-hardening preventing an intrusion from afar instead came out above the War Room through an air vent as it was not air-tight.
As Fisher listened in, the generals present were contacted by Admiral Otomo, who demanded that the military repeal the postwar constitution and return control of Japan to the Emperor so that he could force him to order the immediate remilitarization of Japan. The generals protested the Admiral's demands, so Otomo gave them four days to order the constitution's repeal, after which he would force-launch a North Korean ballistic missile against his own country if his demands were not met. After Otomo cut the transmission the generals, horrified at the Admiral's threat moved forward and deployed a strike team of the GSDF down to the underwater bunker to take control of the facility and stop Otomo. The assault ended in disaster as the entire strike team was massacred by the I-SDF. Enraged at the generals' "dishonorable" actions, Otomo declared that he would go forth with his threat to annihilate one of Japan's major cities. With sufficient evidence that Otomo had been blackmailing the Japanese government the entire time, Fisher proceeded down to the bunker where Otomo was stationed.
On the way down, the I-SDF detects Fisher's presence and cut the power to the elevators. Fisher then climbed down and made his way past the I-SDF forces and a mess of trip wires and wall mines. Fisher was then informed by Lambert that North Korea had informed the U.S. that it lost control of a ballistic missile and that it would launch in a matter of minutes if the I-SDF's servers were not destroyed in time. Fisher moved quickly and was able to overcome the I-SDF's lethal defenses, destroying the servers and canceling the launch. Fisher then confronted Otomo with the intention of capturing him and forcing him to admit to his crimes before an international war crimes tribunal, as his sense of honor would dictate. Otomo scoffed at Fisher's efforts to stop him and instead attempted to commit seppuku with a large blade, but Fisher was able to stabilize him before the wound became fatal. Fisher then blasted his way through the super-thick glass of the bunker and swam up to the surface of Tokyo Bay with Otomo in tow, his wet suit protecting him from near-fatal water pressure. Third Echelon then retrieved Fisher and Otomo, the latter of whom would be forced to admit to his crimes before the world and effectively ending the crisis in East Asia.
