The garden of the embassy was designed by the Japanese landscape architect Junichi Inada (稲田純一), who played a central role in planning Singapore's national parks for nearly half a century.

[2][3] The incumbent ambassador since April 2023 is Eng Chuan Ong, who earned a Bachelor of Engineering degree from Tokyo Institute of Technology in 1993.

[4] On 2 May 2024, it was reported that a Singaporean counsellor, then aged 55, was suspected of voyeuristically photographing a junior high school boy in a public bath in Minato, Tokyo, near the embassy during his tenure as a diplomat.

[5] He had repeatedly committed this offence, and during questioning by the police, he agreed to delete 700 photos he had taken in the public bath.

[6] The Metropolitan Police Department was investigating the case with a view to charges of violation of the Act on Prohibition of Child Prostitution and Pornography (production) and the Act on Punishment of Persons for Taking Photographs of Sexual Desire (filming), but the Embassy of Singapore explained that he had completed his duties as of 12 April and already returned to Singapore.
