Background and overview

Historical background of Okinawa

The region that is now called Okinawa Prefecture in Japan is originally an independent country “Ryukyu Kingdom” established in 1429. The kingdom was subsequently taken under the control of Satsuma by the invasion of Mr. Shimazu in 1609, and was virtually subordinated to Japan. However, at the same time, it contributed to China (then Qing country at that time) and took the form of belonging to both countries. In 1872, the Meiji government set up the Ryukyu Pass, which became an abandoned prefecture in 1879 and became Okinawa Prefecture.
Okinawa is also known to have become a fierce battlefield at the end of World War II as the last line of defense before the mainland Japan battle. In this battle, about 95,000 Japanese military officers and military affiliations, about 12,000 US military officers, and above all 95,000 Okinawan general residents were sacrificed. Continues to torment people.
In December 1950, after the defeat of Japan, it was placed under the occupation of the US military governing body “Ryukyu Islands US Government (commonly known as youth car)”. In April 1952, the Okinawan self-governing body Ryukyu “Government” was established. These institutions survived until May 1972 when Okinawa was returned to Japan.
Currently, Okinawa Prefecture has a strong impression as a base and tourism island, but it also falls into the category with the highest unemployment rate in Japan, which is experiencing the worst economic situation in the ongoing recession. In addition, people who seek jobs from Okinawa and escape to the mainland are unable to withstand, which further deteriorates the prefecture's economy.
Another major problem that Okinawa faces is the US military base. US military seizures that are never returned, noise and environmental damage around the base, crimes such as repeated injuries, thefts, and property damage caused by US soldiers, and above all, the Japanese government's insidious response ... Okinawa is still shaking between the economic reality of creating a certain degree of employment due to the presence of the base and the harmful problems of these bases ignoring the feelings of the residents.

The strategic value of Okinawa and the current state of the base

Currently, there are nearly 40 US bases and facilities on the main island of Okinawa with an area of ​​about 1,200 sq. Km. Its area reaches about 230 square kilometers. By the way, the area of ​​Okinawa Prefecture is only 0.6% of the total of Japan, but 75% of US military facilities in Japan are concentrated there.
Kadena Base is known as the largest and most active US Air Force base in the Far East with two 3700m runways. 54 F-15 fighters etc. are mainly deployed. Futenma Air Base is a leading helicopter base and marine base alongside Iwakuni base among US military bases in Japan. The Futenma base was revised in April 1996, and it was decided to “return to Japan within 5 to 7 years”, but it still gave up over the relocation and construction sites of alternative facilities. .
Camp Hansen, where the Marine Corps conducts live shooting training, occupies the largest site area in Okinawa. Around this area, there are often accidents where live ammunition lands outside the training area.
It has always been said that these US military bases in Okinawa exist for the defense of Japan, an ally. However, in fact, during the Gulf War as well as the Korean War and the Vietnam War, it is used as a source for all-out operations in the Middle East along with the Aomori and Misawa Air Forces and the Yamaguchi and Iwakuni Marines. This shows that it is indispensable for the global military action of the US military rather than Japan. In other words, for neighboring countries that are in conflict with the United States and Japan, the US military power of Okinawa is a threat like a dagger at the throat.

Okinawa Self-Defense Forces and Shimojijima Airport Problem

There are currently less than 5,000 Self-Defense Forces stationed in the Okinawa region in total, land, sea and air. Compared to the fact that there are 40,000 Self-Defense Forces deployed in Hokkaido in preparation for the Soviet invasion during the Cold War, this is far less than the threat of Chinese troops in Asia. However, if a large-scale deployment is carried out in Okinawa, where there is a strong sense of opposition to the base, there will be friction with the residents. In addition, if sufficient strength is deployed in Okinawa near China / Taiwan, it may cause unnecessary stimulation to China. This problem has long been a self-defense dilemma.
However, things started to move in 2001. In fact, Shimojima Island, adjacent to Miyakojima, which is located between Okinawa and Taiwan, has a Shimojima Airport that was built in 1974 for training flight of large commercial jets such as jumbo aircraft. Although the airports on the surrounding islands are runways about 1500m in length, the runway here is 3000m and can be used for military purposes. The Irabu Town Council decided to invite the Air Self Defense Force training base to this airport. For a town that suffers from prolonged recession and financial difficulties, the money that the Self-Defense Forces drop will be a valuable resource.
However, the aim is seen elsewhere. Anyway, if the Self-Defense Forces are deployed here, the distance from the main island of Okinawa to the Senkaku Islands, where Japan, China and Taiwan have given up territorial rights, will quickly shrink to about 200 km. Furthermore, in addition to the Self-Defense Forces, if the US military uses this airport together, the distance from the main island of Okinawa to the main island of Taiwan will be dramatically reduced to about 350 km. This has important implications during a Taiwan emergency.
In fact, in the past one or two years, there have been signs that the U.S. military is actively using the Shimojima airport, such as a US helicopter or aircraft that has been practicing during the exercise. The strategic importance of is told. However, it is no wonder that the Chinese side thinks that if this airport is made into a full-scale base even for training purposes, it will be more threatening than the base on the main island of Okinawa. It is unknown how the Chinese military will behave at that time.

Okinawa Defense Battle / Miyakojima Sea Battle

Scenario status settings

On the eve of 200X, Chinese naval infantry camouflaged as fishing boats on the Senkaku Islands, Ishigakijima, Miyakojima, Irabujima, Shimojijima, and Taramajima landed assault, as well as airborne and special forces, etc. Was captured electrically. The Chinese military seems to have developed several airports, such as Shimojijima Airport, as air bases, augmented fighters, anti-ship missiles, anti-aircraft weapons, and other anti-ballistic missiles.
Also, in order to support these landing units, a joint fleet main force of the Yellow Sea and Tokai of the Chinese regular navy has been deployed in the surrounding waters, some of which are further aimed at Kumejima and Okinawa Main Island.
Currently, the main forces of the US military in Japan have been mobilized for wars in the Middle East, and Okinawa's defenses were extremely weak. China's invasion is a form of imagination.
Informed sources analyzed the background of this invasion as follows. First, the Chinese Communist Party decided that the intensified Middle East war couldn't turn the troops committed to recapture Okinawa into the US. Second, taking advantage of the turmoil in the Middle East, a strategy to merge Taiwan with armed forces based on the Okinawa region is planned.
And thirdly, in the waters near the Senkaku Islands, where China, Taiwan and Japan are also occupying territorial rights, China recently discovered a large-scale submarine resource in secret, and in order to mine it, It is thought that it was necessary to neutralize the US-Japan military power around Okinawa, which is a threat behind.
In particular, Shimojima Airport, which was scheduled to start full-scale operation of the SDF base soon, would eventually be used as a common base for US forces in Japan. The distance between the main islands will be drastically reduced from about 450 km to about 200 km, and the distance between Taiwan and Okinawa main islands will be drastically reduced from about 600 km to about 350 km. Expected. Therefore, it seems that it was extremely important for China to strike or occupy this in advance.

About maps

The enemy is divided into troops that have landed on Miyakojima, Ishigakijima, etc., and the main force of the navy down the East China Sea.
In this case, the enemy fleet's main force is invited to the edge of the air cover from Okinawa main island / Kumejima, first hit the enemy air force main force / navy force main force with high air power of each individual destruction power, then both Miyakojima and Ishigakijima The direct attack method is to recapture the island. However, if it is recaptured only at the airports on both islands, you can pinch the enemy ship against the main power. The speculation is high, but if it succeeds, it will be settled in a short time. In any case, it is important to use the units deployed on the remote islands.

Okinawa Defense Battle / Naha Fall

Scenario status settings

The Chinese army occupied Kumejima, Yasukunijima, and the Kerama archipelago one after another with Miyakojima and Ishigakijima as the front line base, and carried out landing operations on the main island of Okinawa using these as relay bases. The landing site is in the suburbs of Itoman, and has already built a coastal shore and landed a series of ground units including heavy weapons such as tanks, self-propelled guns, ground missiles, and self-propelled rocket guns.
Naha was being besieged and the garrison was isolated among the enemies. The Self-Defense Forces in Okinawa and the US military stationed in Japan have gained some support through air transport, and both the ASDF and the MSDF are collecting and deploying operational aircraft from various units. In addition, GSDF Type 90 tanks and Type 99 self-propelled howitzers are transported by the US Army's C-5 Galaxy and C-17 Globemaster III. However, the large-scale reinforcements of the SDF ground units from the mainland are still in the middle because of the time it takes to organize and mount them on transport ships, and it is difficult to say that sufficient quantities have been secured.
Most of the US troops in the US mainland and Hawaii have already been put into the Middle East, and ready-made national guards and reserves are in the same state. The US military headquarters in Japan estimates that it will take another two weeks from Hawaii to send reinforcements to Okinawa.

About maps

The main battlefield on this map is Okinawa Main Island. Japan and the US have secured the islands such as Iheyajima and Yoronjima from the central part of the main island to the north and north of Iejima.
However, the Chinese army who secured a bridgehead in Itoman has expanded its control area by landing armored units and heavy weapons. Here, if Naha Airport, which is the front light, and Futenma / Kadena Base are occupied, it will be difficult to secure the right to control the air, and the anti-attack operation will be hopeless. The main island of Okinawa, like Honshu, is slender from north to south and has no vertical depth. For this reason, it is disadvantageous to protect, so please pay special attention to these base defenses.
At this stage, the Chinese army has lost many ships before the powerful Japanese and US maritime forces. It may be said that the sea control right is temporarily on the Japanese and US sides. Therefore, I would like them to efficiently allocate these superior marine forces and air force distributed on the northern islands to secure air control and support the ground.
In the narrow main island, refugees run away toward the north, so it is necessary to keep that in mind when advancing.

Okinawa Defense Battle / Yanbaru Battle

Scenario status settings

The Japanese and U.S. troops, who were forced to fight back in the battle, were forced to fight under a lack of troops, and were attacked by intense ballistic missiles and ground missiles. Being driven away.
The Chinese troops who landed on the main island of Okinawa from the suburbs of Itoman City seemed to have been almost swept away at a time, but after that, they recovered their power by receiving a large number of increase, and air support from the direction of Miyakojima, Shimojijima, Kumejima With the overwhelming amount of marine forces in the background, the majority of Okinawa Island has already been successfully controlled.
The Kadena Air Force Base and Futenma Base, which were the bases of air support by the Japanese and US troops, have already fallen, and more seriously, a ground ballistic missile base has been constructed near Naha, which has caused major psychological damage to the inferior Japanese and US troops. Giving. In addition, there is a need to control evacuees, and there is no denying that evacuees who are embarrassed are making effective counterattack difficult.
Both the Self-Defense Forces and the US Army in Japan are truly backwaters. However, the Chinese army, who is willing to suffer weapons as well as human damage, has already lost many of its main aircraft, and depending on the future operations, our army should be able to recover from the inferiority.
According to the announcement by the Japanese government, the MSDF assault landing ship Osumi-class landing team that departed from Kure Port is approaching the main island, protected by an escort fleet with the light aircraft carrier Akagi-class flagship. That's it. If you can defend the landing unit with air power including aircraft carriers, there will be enough wins.
However, there is information that the remaining Chinese naval forces are deployed in the waters near the main island. Encountering an escort fleet will lead to fierce naval battles.

About maps

US and Japanese ground troops are driven to the north of the main island, and they must counterattack the displaced people. However, the number of evacuees has declined considerably, so you may not need to worry too much.
The reinforcement unit's assault landing ship Osumi class is equipped with the LCAC of hovercraft, which allows for flexible landing operations and is a good place to use. It may be a hand to focus on where the strength between the enemy's front and rear is weak. The SDF is supposed to be able to send the newly formed MSDF special forces to the back of the enemy land by submarine (special submarine for classification in the game), so this is also effective Let's use it.
If you have secured the right to control the air, we would like to consider carrying out a helibone to recapture the city and fight back there.
If you get the main island medals, you may try to eliminate the enemy that occupies the islands west of the main island. In this case, advancement using LCAC or helicopter is efficient, but it is not a direct victory goal, so it should be done only when there is room. This is because it is too risky to force the Chinese fleet into a healthy early stage.
