It is located in Okinawa Prefecture and encompasses the city of Naha and parts of Shimajiri District (Kumejima, Tokashiki, Zamami, Aguni, Tonaki, Minamidaitō, Kitadaitō).

The Japanese Communist Party (JCP) has also maintained a relatively large share of vote in the district, banking on the urban voter support and local opposition to the US military bases in Okinawa.

The anti-base camp aligned to Okinawa Governor Takeshi Onaga created an alliance behind Akamine to oppose the LDP incumbent at that time, Kōnosuke Kokuba.

Kokuba supports the relocation of the US air base in Futenma to Henoko, following the policy of the LDP and Prime Minister Shinzo Abe.

A strong anti-base vote and the split in the centre-right camp delivered the district to Akamine, completing JCP's surge in the election.
