According to "Histoire Ecclesiastique Des Isles Et Royaumes Du Japon", written by Pere François Solier of the Society of Jesus in 1627, Yasuke came from ”Moçambique”. "Moçambique" indicates Island of Mozambique in those days.
Yasuke is mentioned in some of the 1581 letters of the Jesuits Luis Frois and Lorenço Mexia and in the 1582 Annual Report of the Jesuit Mission in Japan. These were published in Cartas in 1598. They are translated in full in Vols. 3-5 and 3-6 of Juuroku... and there is no reference to him in Frois's History.
Yasuke arrived in Japan in 1579 as the servant of the Italian Jesuit Alessandro Valignano, who had been appointed the Visitor (inspector) of the Jesuit missions in the Indies, i.e. S. and E. Asia, an extremely high position, so Yasuke must have been quite trustworthy. He accompanied Valignano when the latter came to the capital area in March 1581 and caused something of a sensation. In one event, several people were crushed to death while clamouring to get a look at him. Nobunaga heard about him and expressed a desire to see him. Suspecting the black color of his skin to be paint, Nobunaga had him strip from the waist up and made him scrub his skin.
Nobunaga's nephew gave him money. In May, Yasuke accompanied a group of Jesuits on a short trip to the province of Echizen. Yasuke could speak some Japanese, so Nobunaga enjoyed talking with him and was also impressed by his strength. At Nobunaga's request, Valignano left Yasuke with Nobunaga before Valignano left central Japan later that year. Nobunaga treated Yasuke with such great favor that people in Azuchi even said he would probably be made a 'tono' (lord). This did not happen, but he was given the position of samurai (shikan).
In June 1582, Nobunaga was attacked and killed in Honnō-ji in Kyoto by the army of Akechi Mitsuhide. Yasuke was also there at the time. Immediately after Nobunaga's death, Yasuke went to the lodging of Nobunaga's heir Oda Nobutada and withdrew with him to Nijō Castle. When that too was attacked by Akechi, Yasuke fought alongside the Nobutada forces for a long time. Finally he surrendered his sword to Akechi's men. They asked Akechi himself what to do with him. Akechi said that the black man was a beast and did not know anything, and furthermore, he was not Japanese, so they should not kill him but take him to the church [in Kyoto] of the Visitor from India, so they did, much to the relief of the Jesuits there who had worried about him. There is no information about him after that.
The "Lord Nobunaga Chronicle" (信長公記 Shinchōkōki) has a description of Yasuke's first meeting with Nobunaga. "On the 23rd of the 2nd month [March 23, 1581], a black page (黒坊主 "kuro-bōzu") came from the Christian countries. He looked about 26 [24 or 25 by Western count] or 27 years old; his entire body was black like that of an ox. The man was healthy and good-looking. Moreover, his strength was greater than that of 10 men."
After Matsudaira Ietada had met Yasuke in May 1582, Ietada journalized his looks. " His name was Yasuke. His height was 6 shaku 2 sun (6 ft. 2 in., or 188 cm.). He was black, and his skin was like charcoal." If so, his tall stature would have been very imposing to the Japanese of the day.
Yasuke was also mentioned in the prototype of Shinchōkōki owned by Sonkeikaku Bunko (尊経閣文庫). According to this, Yasuke was given his own house and a short katana by Nobunaga. Nobunaga also assigned him the duty of "Dōgumochi" (道具持ち), the porter of his Yari
- Yasuke was featured in the children's historical fiction novel, Kuro-suke (くろ助) by Yoshio Kurusu with illustrations by Genjirou Minoda, published in 1943. It features a highly fictionalized and sympathetic account of Yasuke's life in Japan under Nobunaga. It received the Children's Prize of the Japanese Association of Writers in 1969.
- Yasuke is the protagonist of Shūsaku Endō's novel Kuronbō in 1971.
- Yasuke also appears as a character in 30th Taiga Drama, Nobunaga, and 35th Taiga Dorama Hideyoshi.
- In the manga Hyouge Mono, Yasuke saw the true culprit of the Incident at Honnōji, then he was confined by Hashiba Hideyoshi. Later he was saved by Furuta Oribe. In the Anime, Yasuke is voiced by Takaya Kuroda.
- The character of the manga and anime Afro Samurai was partially based in Yasuke.
- The character of the samurai Genbei "Jaguar" Yagyu from the Neo Contra PlayStation 2 video game was also based in Yasuke.
Misleading or unsubstantiated information
Since there is little that can be known about him, many have written without knowing much about him.
Some accounts say he was killed in Honnō-ji, but this is clearly incorrect, since it contradicts the only source associating him with the Honnō-ji incident at all. Statements that he was sent to a monastery are likely based on Akechi's sending him to the Jesuit church.
