is a Japanese politician, a Liberal Democrat member of the House of Councillors in the Diet (national legislature)[1] who was elected for the first time in 2007 and re-elected in 2010 in Okinawa Prefecture constituency.[2] Shimajiri was appointed the Minister of State for Okinawa and Northern Territories Affairs in the cabinet reshuffle on October 7, 2015, and is one of 3 women serving in Shinzo Abe's cabinet.[3]
In an interview following her appointment as the minister of state, Shimajiri stated that she will not deal with issues regarding the construction of new U.S. military facilities in Okinawa.[4]
Shimajiri lost her Diet seat to former Ginowan, Okinawa mayor Yoichi Iha, a critic of the US military presence in Okinawa supported by a coalition of opposition parties, in the 2016 Japanese House of Councillors election. This was viewed by some analysts as a setback for the proposed relocation of Futenma.[5]
