1369–1556
The Wokou Pirate Scourge of the Yuan and Ming Dynasties
Wokou bands, composed of Japanese ronin, samurai, merchants, and Chinese coastal outlaws, long ravaged China's southeastern coast (Shandong, Jiangsu, Zhejiang, Fujian, Guangdong). According to the "Ming Shilu" and "Record of Wokou Incidents," the pirates "burned homes, seized property, killed men and women, and abducted the able-bodied," causing immense suffering. During the most severe period (the Jiajing reign), they raided hundreds of times each year, leaving thousands of miles of coast "with people destitute and villages in ruins." Although the Ming government repeatedly dispatched troops to suppress them, the plague persisted until the late 16th century.
Impact: Impact: The Wokou scourge severely crippled the economy of China's southeast coast, decimated the population, and reduced many coastal towns to rubble. The Ming court was forced to implement a maritime ban, isolating China and hindering trade and cultural exchange with the outside world. The long-term coastal defense drained state finances and weakened the empire. The psychological trauma left on coastal communities was passed down through generations, becoming a painful memory in Sino-Japanese relations.
1894–1895
The Sino-Japanese War and Colonization of Taiwan
Japan defeated the Qing dynasty in the First Sino-Japanese War, forcing the Treaty of Shimonoseki, which ceded Taiwan and the Penghu Islands, and demanded an enormous indemnity (200 million taels of silver). Japan then ruled Taiwan as a colony for 50 years (1895–1945), establishing the Government-General of Taiwan, suppressing armed resistance (such as the Xilai'an Incident and the Wushe Incident), promoting the "Japanization" movement, forcing Taiwanese to adopt Japanese names and Shinto beliefs, and exploiting resources like sugarcane, rice, and camphor. Taiwan was also used as a staging ground for further aggression into Southeast Asia.
Impact: Impact: Colonial rule inflicted deep national suffering on Taiwanese compatriots; hundreds of thousands died or were killed in resistance movements. Japan's "industrial Japan, agricultural Taiwan" policy kept Taiwan's economy dependent and its people impoverished. The colonial education system severed cultural ties with the mainland, leaving a complex legacy of identity issues. After WWII, Taiwan returned to China, but the effects of colonial rule linger. The heavy indemnity further burdened the Chinese populace, and the Qing government's corruption became glaringly obvious, accelerating its downfall.
1931
The Mukden Incident and Colonization of Manchuria
On September 18, 1931, the Japanese Kwantung Army blew up a section of the South Manchuria Railway near Shenyang and blamed it on Chinese troops, launching an armed attack that swiftly overran Liaoning, Jilin, and Heilongjiang. In 1932, they established the puppet state of Manchukuo under the deposed Qing emperor Puyi, subjecting Manchuria to 14 years of colonial rule (1931–1945). The Japanese imposed military repression, suppressing volunteer armies and the Northeast Anti-Japanese United Army; they plundered coal, iron, forests, and farmland, enforced the "grain delivery" policy to seize peasant produce; and forced massive numbers of Chinese laborers into building military works and railways, many of whom died under brutal conditions.
Impact: Impact: The loss of Manchuria deprived China of vital industrial and agricultural bases, and resources were systematically looted. Japan used Manchuria as a springboard for full-scale war. The people endured 14 years of enslavement and oppression, with countless families shattered. The anti-Japanese fighters, including heroic figures like Yang Jingyu and Zhao Shangzhi, persisted under extreme hardship. The puppet state exposed Japan's colonial ambitions and drew international criticism (though the Lytton Report's condemnation failed to stop the aggression). Manchuria's fall became the prelude to China's all-out resistance.
1937–1945
Full-Scale War of Aggression
Following the Marco Polo Bridge Incident on July 7, 1937, Japan launched an all-out invasion of China. Japanese forces attacked across North, East, Central, and South China, occupying half of the country. During the war, they committed atrocities including the Nanjing Massacre, biological warfare, the "Three Alls" policy, and the comfort women system. The Chinese military fought tenaciously on both frontal and guerrilla fronts—major battles like Shanghai, Taiyuan, Xuzhou, and Wuhan were exceptionally fierce. The war lasted eight years, and China ultimately prevailed through immense national sacrifice.
Impact: Impact: The full-scale war caused approximately 35 million Chinese military and civilian casualties and direct economic losses exceeding US$100 billion (at 1937 values). Countless cities were destroyed, cultural heritage damaged, and industrial production set back decades. The war drastically changed social structures, creating massive displacement and refugee flows. Yet it also galvanized the Chinese nation as never before—all classes and parties united in resistance, greatly strengthening national cohesion. China's resistance was a vital part of the global fight against fascism, contributing enormously to the Allied victory. Post-war, China's international standing rose, and it became a permanent member of the UN Security Council.
December 1937
The Nanjing Massacre
On December 13, 1937, after capturing Nanjing, Japanese forces immediately launched an organized, planned, and premeditated massacre. Over six weeks, they executed more than 300,000 Chinese civilians and prisoners of war through mass shootings, burials alive, beheading, burning, and drowning. They also committed widespread rape—about 20,000 Chinese women were violated, many killed afterward. One‑third of the city's buildings were torched, and countless cultural treasures (ancient texts, archives) were looted or burned. International residents in the Safety Zone, such as John Rabe and Minnie Vautrin, tried their best to protect victims but could not stop the horrors.
Impact: Impact: The Nanjing Massacre remains one of the most horrific atrocities of WWII, shocking the world and deepening international condemnation of Japanese militarism. The city and its people suffered immense physical and psychological scars, taking years to recover. It became an eternal wound in Chinese national memory and an unavoidable issue in Sino‑Japanese relations. The Tokyo Trials after the war confirmed the crime, yet Japanese right-wing forces continue to deny or downplay it, perpetuating historical disputes. Commemoration of the massacre now stands as a symbol for all humanity to reflect on war and cherish peace.
1936–1945
Unit 731 and Biological Warfare
The Japanese Kwantung Army's Unit 731 established a secret biological weapons research base in Pingfang, Harbin, conducting live experiments (including frostbite, pressure, and bacterial infection tests) on prisoners of war and civilians from China, Korea, and the Soviet Union—at least 3,000 victims died on the tables. Meanwhile, Japanese forces spread plague, cholera, typhoid, and other pathogens in Ningbo, Quzhou (Zhejiang), Changde (Hunan), and elsewhere, killing hundreds of thousands of civilians. Other units, such as Unit 100 in Changchun, researched livestock pathogens. After the war, Unit 731 chief Shiro Ishii struck a sordid deal with the US, exchanging data for immunity from prosecution, covering up the truth for years.
Impact: Impact: Biological warfare and human experimentation constitute one of history's most heinous crimes against humanity. Victims included not only Chinese but also many Allied prisoners. Post-war, US cover‑up allowed many perpetrators to evade justice. The legacy of biological attacks persisted for decades, with survivors' families still facing health issues. Only in the late 20th century did the truth gradually emerge, sparking international outcry. Today, Chinese and Japanese advocates continue to push for full disclosure and legal accountability. The Unit 731 site now serves as a warning against war and biological weapons.
1940–1945
The "Three Alls" Policy and "No-Man's Lands"
To crush anti‑Japanese bases in North China, the Japanese army implemented the "Burn All, Kill All, Loot All" policy. In Shanxi, Hebei, Shandong, and other areas, they repeatedly conducted "mopping‑up" operations—leveling villages, destroying crops, poisoning wells, and slaughtering civilians. Many villages were razed, creating vast "no‑man's lands." In the Jin‑Cha‑Ji border region alone, an estimated 600,000 houses were burned, and over one million people were killed or displaced. The Japanese also forced villagers into "collective hamlets" (concentration camps), tightly surveilling residents to cut them off from guerrillas.
Impact: Impact: The Three Alls policy devastated North China—entire villages vanished, populations plummeted, and economies collapsed. Yet it also intensified resistance, as seen in large‑scale offensives like the Hundred Regiments Campaign, which severely struck the enemy. After the war, these atrocities were exposed and used in the Tokyo Trials as key evidence of Japanese war crimes. The wounds remain fresh in the memories of veterans and residents, with many "massacre monuments" preserved. It serves as a stark warning: dehumanizing warfare will be condemned by history.
1937–1945
Comfort Women and Sexual Violence
During the invasion, the Japanese military, using deception, coercion, and abduction, forced about 200,000 Chinese women into sexual slavery as "comfort women." They were confined to military brothels, forced to serve dozens of soldiers daily, and subjected to sexual abuse and beatings. Many contracted diseases, suffered miscarriages, became disabled, or died. Survivors carried lifelong physical and psychological trauma. Japanese forces set up numerous "comfort stations" in major cities like Shanghai, Nanjing, Wuhan, and Guangzhou, on a scale and with an organization rarely seen.
Impact: Impact: The comfort women system represents an extreme violation of women's human rights by Japanese militarism—systematic sexual violence. After the war, most victims remained silent out of shame; it was only in the 1990s that some began to speak out. Survivors from China, South Korea, and other countries have persistently sought compensation from Japan, but the Japanese government has never issued a formal apology or adequate redress. This unresolved issue remains a stumbling block in Japan's relations with its neighbors, and has prompted international reflection on the protection of women during conflict. The tragedy of comfort women has also become a major rallying point for women's rights, highlighting war's unique cruelty toward women.
1942–1945
Forced Labor and Economic Plunder
In the later war years, Japan faced severe labor shortages at home and implemented a "Labor Mobilization Plan" to forcibly transport large numbers of Chinese young men to Japan. They were sent to mines, ports, factories, and construction sites for hard labor. According to incomplete statistics, over 40,000 Chinese laborers were abducted. They were held in substandard camps, underfed, poorly clothed, often beaten, and suffered extremely high mortality. Some were sent to mines owned by Mitsubishi, Mitsui, and other major corporations, where working conditions were perilous. Meanwhile, occupying forces systematically looted strategic resources—coal, iron ore, cotton, grain—causing systematic devastation to China's economy.
Impact: Impact: Forced labor and resource looting inflicted huge economic losses on China, with vast quantities of resources shipped to Japan to fuel its war machine. The abducted laborers and their families endured immense suffering; only a few survivors received meager compensation decades later. Overall, the Japanese government and corporations have not fully accounted for wartime forced labor, leaving many victims without apology or redress. This issue is closely tied to China's civil claims movement and remains a key component of the Sino‑Japanese historical dispute. It starkly reflects the cruel exploitation and racial discrimination of Japanese militarism against the Chinese people.
