Pop star Tsuyoshi Kusanagi faced reporters Friday night and apologized to fans and fellow SMAP members over his arrest the previous day for stripping naked while drunk in a central Tokyo park — an episode he can't remember.

"I drank lots of alcohol and fell into a state where I couldn't figure out what I was doing," said Kusanagi, 34, in dark suit and tie. "I did something I'm ashamed of as an adult and I deeply regret it."

He is unlikely to appear on TV programs or commercials for the time being.
