Secret training ground

Secret training grounds are a recurring theme in Bleach. Characters frequently study to improve or master their powers in large hidden rooms, which are often decorated in such a way as to have the appearance of an outdoor wilderness on a sunny day.

Urahara Shop training ground
Before beginning his mission into Soul Society to rescue Rukia Kuchiki, Urahara Kisuke takes Ichigo Kurosaki to a huge secret training ground beneath the Urahara Shop. Here, over a period of several days, Urahara helps Ichigo regain his lost Shinigami powers and teaches him the basic techniques of Shinigami combat. Ichigo's partial transformation into a Hollow also takes place here, and Urahara opens the Senkaimon into Soul Society from this room.

The Urahara Shop training ground is a large room with a ceiling and walls resembling a cloudy sky over a floor of desolate, brown, craggy land.

The final, staged confrontation between the Ryoka and the Mod Souls Ririn, Kurodo and Noba also takes place in the training ground.

The training ground is used again by Yasutora Sado as he spars with Renji Abarai to master higher levels of his power; from there, Ichigo, Chad, and Uryū Ishida make their way through the garganta into Hueco Mundo.

Sōkyoku Hill training ground
Urahara styled his shop's secret training ground on one he built beneath Sōkyoku Hill while young. In this training ground, he and Yoruichi Shihōin would play and train. When Ichigo Kurosaki narrowly escapes defeat by Byakuya Kuchiki, Yoruichi takes him to this training ground in order that he might rapidly attain bankai through use of the Tenshintai. Renji also attains bankai in this space.

While very similar in apperance to the Urahara Shop's training ground, the Sōkyoku Hill training ground also sports a hot springs whose waters have the power of healing injuries.

Vizard warehouse training ground
Beneath the Vizard's warehouse hideout is another secret training ground, bearing a strong resemblance to those beneath the Urahara Shop and the Sōkyoku Hill. Ichigo's mastery of his inner hollow and his training with the Vizard takes place here; Orihime Inoue also meets and befriends Hachigen Ushōda here as he heals Tsubaki.

Karakura Hospital training ground
Ryūken Ishida has constructed a training area inside Karakura Hospital. In this stark, metallic chamber, Ryūken fights Uryū to exhaustion, finally shooting him with a Quincy arrow to restore his lost abilities.
