 On 8 May 2014, De Boer-Buquicchio was appointed Special Rapporteur on the sale of children, child prostitution and child pornography. From 12 to 18 May the following year she visited Armenia to investigate violence against children.
 From 19 to 26 October 2015, De Boer-Buquicchio traveled around Japan (Tōkyō, Ōsaka, Kawanishi and Naha) for eight days to investigate child trade, sexual exploitation, production of child pornography etc. and she held a press conference at Japan National Press Club in Tokyo on 26 October to report the results.
 On 2 November 2015, the Japanese Ministry of Foreign Affairs (MOFA) issued a complaint to the Office of the High Commissioner for Human Rights (OHCHR) over De Boer-Buquicchio's comment of 26 October, which they quoted as saying that 13% of schoolgirls were involved in enjo kōsai ("compensated dating"), and asked her to disclose the source for the claim of 13%.
 In response, the OHCHR released a clarification from the Special Rapporteur acknowledging that she had not received an official statistic concerning this matter while in Japan and explaining that the 13% figure was an estimate found in open sources that was mentioned – thanks to a mistranslation, as 30% – to highlight a phenomenon that must be urgently tackled.[non-primary source needed]
 Following the issuing of a press release[non-primary source needed] by the Ministry of Foreign Affairs on 9 November in which it requested the withdrawal of the remark and that the report be based on objective data, she addressed on 10 November a letter to the Permanent Representative at the Permanent Mission of Japan to the United Nations in which she stated that she would not refer to this estimate in her Report to the UN Human Rights Council.
 The final report was presented to the UN Human Rights Council in New York on 3 March 2016.
