A Liberal Democratic Party lawmaker apologized on Monday for shouting a sexist remark last week at a female colleague from Your Party during a plenary session of the Tokyo Metropolitan Assembly.

Akihiro Suzuki, 51, apologized at a news conference at City Hall five days after the sexist taunting incident, which allegedly involved at least one other male lawmaker.

"I apologize from the bottom of my heart for inflicting heavy heartache and causing trouble to assembly member fellow lawmaker Ayaka Shiomura, the assembly and the public, caused by my remark, 'Why don't you get married soon?' " the nationalist lawmaker said.
