The search was prompted by officers’ discovery of what appeared to be liquid cannabis in Okamoto’s possession when he was questioned on a street in Tokyo’s Shibuya Ward around 2 a.m. the same day.

Okamoto, who also goes by the name “Sean,” shot to popularity on social media after starring in the series “Terrace House: Opening New Doors,” which premiered on Netflix Japan in 2017. As of Monday, he had over 210,000 Instagram followers.

The most recent series of Fuji Television’s reality TV was terminated following the death of one of the cast members in a suspected suicide after receiving hateful messages online.
