On this day 46 years ago, on June 11, 1979 (May 17, 1979 lunar calendar), Kenzo Nakajima, a Japanese social activist, passed away. On June 11, 1979, Kenzo Nakajima, a famous Japanese social activist, passed away due to lung cancer. Kenzo Nakajima was a sincere friend of the Chinese people. He dedicated the rest of his life to the cause of friendship and cultural exchanges between the people of China and Japan. His contributions to Sino-Japanese friendship and cultural exchanges will be recorded in the annals of history and passed down to future generations. Kenzo Nakajima was born on February 21, 1903. A month before his death, he was elected as the president of the Japan-China Cultural Exchange Association. He was one of the pioneers of cultural exchanges between China and Japan after the founding of New China. From the mid-1950s, he resolutely devoted his whole body and mind to the cultural exchanges between Japan and China. The Japan-China Cultural Exchange Association, which he founded and led, became one of the most influential and contributing groups to the cause of Sino-Japanese friendship after the war. At that time, right-wing forces opposed to Japan-China friendship and New China were still rampant in Japan. Kenzo Nakajima received many threatening letters and phone calls, some of which contained several bullets. But Mr. Nakajima was calm every time and smiled it off. Once he jokingly told a Chinese friend that "if there is a situation where anonymous letters and anonymous phone calls threaten me, I have nothing to fear. At that time, I can only ask Chinese friends to take care of my wife." At that time, Mr. Asaki Inagiro of the Japanese Socialist Party was assassinated to promote friendship between Japan and China. After that, there were also right-wing violent groups that threatened and intimidated Mr. Nakajima, but Mr. Nakajima did not flinch at all. There was a period when the Hong Kong authorities did not allow Mr. Nakajima to cross the border, and he had to go all the way around Phnom Penh to come to China. In 1942, Kenzo Nakajima was once conscripted to serve as a military reporter. He saw that the Japanese army used the excuse of issuing "good citizen certificates" to arrest a large number of so-called anti-Japanese overseas Chinese without basis, and took them to the coast and sea to kill them all with machine guns. Later, the mother of the overseas Chinese took the photo of his son and asked him about the whereabouts of his son. He was deeply distressed, which was impossible to express at the time in the battlefield. It was in this heart of long-buried distress that he was convinced that Sino-Japanese relations would determine the future fate of Japan. On this issue, Kenzo Nakajima's later book "The Thought of the Defender - French Literators and China" opens a chapter with clear meaning and is very detailed. In the book "Showa Times", there is also a chapter "Mother of Overseas Chinese - Tragedy in Singapore" that also expresses this mood. Kenzo Nakajima is not only an ambassador of Sino-Japanese friendship, but also an outstanding writer and critic of contemporary Japan. He has translated Balzac's "Preface to Human Comedy", Baudelaire's art treatises, and written "The Life and Works of Gide" and so on.
