Rukongai

, also known as the Rukon District in the English Dub, is the largest portion of Soul Society and the most populated.

Overview
Rukongai is divided into 320 districts (80 in North Rukongai, 80 in West Rukongai, etc.), each numbered in descending order on how far they are from the center; this results in the higher-numbered (and farther) districts decaying into slums. Thus, while District 1 is peaceful and lawful, much like the antiseptic lifestyle of early-Edo Era Kyoto, District 80 is a hardscrabble, violent, crime-infested area that more depicts Heian era Kyoto. The duties of the Gotei 13 Divisions include defending allocated districts of Rukongai. However, which division is responsible for which district has not been stated.

101 years ago, many souls in Rukongai mysteriously vanished due to the experiments of Sōsuke Aizen. These occurrences continued for about a month before the Shinigami sent Kensei Muguruma and a team from the 9th Division to investigate. The Visored were Hollowfied in a forest in the west of the 6th ward of the Fugai District on the same that the 9th Division team arrived to begin their investigation. Tessai Tsukabishi used forbidden Kidō to teleport the Visored back to the lab of Kisuke Urahara in Seireitei in a bid to save them.

Once again, now in the present, many souls have been disappearing in the 64th district.
