Kusanagi is one of the most popular celebrities in Japan
A Japanese pop star has been arrested for public indecency after being found drunk and naked at a park in Tokyo, police have said.
Tsuyoshi Kusanagi, of the boyband SMAP, was found alone and "shrieking at the top of his voice" in the early hours of Thursday, according to media reports.
The Kyodo news agency reported that the 34-year-old asked a police officer: "What's wrong with being naked?"
Kusanagi's agents apologised "for the trouble and worry caused to everyone".
Kusanagi shot to fame almost 20 years ago as a member of the popular boy band whose five members have gone on star in a number of films and television programmes.
Toyota Motor Corp have pulled commercials starring Kusanagi.
And Japan's communications minister Kunio Hatoyama has expressed anger because the actor was the face of a government campaign to get the public to switch to digital television.
The agency representing Kusanagi said it would make a further announcement on his future career.
In Japan, public indecency carries a penalty of up to six months in prison or a fine of up to 300,000 yen (£2,100).
