Prosecutors have indicted former actress Saya Takagi, who advocated legalization of medical marijuana while running in July's Upper House election, on charges of violating the Cannabis Control Law.

Takagi, 53, was indicted Tuesday along with two housemates — Shigenari Moriyama, 58, and Yuki Omi, 26 — after the Health, Labor and Welfare Ministry's narcotics control department arrested them Oct. 25.

Around 55 grams of marijuana was discovered at their home on Ishigaki Island in Okinawa Prefecture, according to the indictment.

The department raided their home and confiscated a pipe and rolling papers believed to have been used to smoke the drug.

Takagi, whose real name is Ikue Masudo, ran unsuccessfully for an Upper House seat from a Tokyo district on the Shinto Kaikaku (New Renaissance Party) ticket. She made her acting debut in 1983.
