Karakura Town

Karakura Town is a fictional town or city in Western Tokyo in the Human World, where the story of Bleach begins. It is also the home town of the main character, Ichigo Kurosaki. It seems to be a small city with an average population. It resembles the real world on the surface, and the everyday humans in Bleach are unaware of the ghosts and spiritual forces with which the plot concerns itself. Sōsuke Aizen seeks to destroy Karakura Town to make a copy of the King's Key. Karakura Town is referred to as District 3600 by the Shinigami and is situated on the current "juureichi" - the point in the Human World that possess the greatest concentration of spiritual beings.

Fake Karakura Town arc
Knowing that Aizen and the Espada were planning to destroy Karakura Town to create the king's key, Mayuri Kurotsuchi and the 12th Division constructed a perfect replica of Karakura Town in a remote corner of Soul Society and switched it with the real one after putting all the people of the town into a deep sleep.

To hold the fake Karakura inside of the real world, four towers were put in place, but these towers are soon targeted by Barragan Luisenbarn and four of his Fracción. Yumichika Ayasegawa, Izuru Kira, Shuhei Hisagi and Ikkaku Madarame are sent to defend those towers. While the first three towers are successfully defended, Ikkaku is defeated by the Arrancar Choe Neng Poww because he refused to release his Bankai and fight at his full strength, and one of the towers falls as a result. Before Karakura begins to partially reappear in the real world, Sajin Komamura and Tetsuzaemon Iba arrive and Komamura kills Poww while Tetsuzaemon uses some type of rods to keep the Fake Karakura Town from disappearing.

The battle against Aizen and the top three Espada is still being waged over the Fake Karakura. The only battle actively continuing at the moment is Shunsui Kyōraku and Jūshirō Ukitake facing Starrk, the Primera Espada, while Barragan and Tia Harribel have apparently been defeated by Soifon and Hitsugaya, respectively.
