Tsuyoshi Kusanagi, 34, of the popular music group SMAP, will not be charged with public indecency in connection with his April 23 arrest after being found naked and drunk in a central Tokyo park, prosecutors said Friday.

Kusanagi was arrested naked and drunk in the park at around 3 a.m. and sent to prosecutors and released on April 24.

On why he was not indicted, an investigative source said Kusanagi, who was arrested next to the landmark Tokyo Midtown complex in the Roppongi-Akasaka district, regrets his act and has no criminal record.

The incident has cost Kusanagi, who is also popular in South Korea and other parts of Asia, lucrative endorsement contracts and TV appearances. He has also refrained from entertainment activities.

Appearing in a packed press conference on April 24, hours after his release, Kusanagi apologized to his fans in Japan and other parts of Asia and said he does not know when he can resume his activities as a celebrity.
