The Campaign Against a Surveillance Society has written to the local office of Google to request that the service be discontinued in Japan as it violates the public's privacy.
The innovative function provides a 360-degree, street-level view of hundreds of spots across Japan. It caused controversy shortly after its introduction in the country, however, when some images showed the faces of men and women entering short-stay "love hotels" in Tokyo's Shibuya nightlife district.
Yasuhiko Tajima, a professor of constitutional law at Tokyo University and head of the group opposed to Street View, told Reuters: "We strongly suspect that what Google has been doing deeply violates a basic right that humans have.
"It is necessary to warn society that an IT giant is openly violating privacy rights, which are important rights that the citizens have, through this service."
Google Japan failed to return calls to the company's offices on Monday, but a statement on the Google website said, "Street View only features photographs taken on public property and the imagery is no different from what a person can readily see or capture walking down a street.
"Imagery of this kind is available in a wide variety of formats for cities all around the world. We are committed to respecting local laws and norms in each country in which we launch Street View."
The company uses blurring technology and permits anyone featured in an image to have it removed from the service, a Google spokesman said.
Similar privacy concerns have been raised in Europe and Canada, while the service was the target of a private lawsuit earlier this year in the United States.
