What goes up must come down, but it isn’t always as painful as this.

A 150-student strong human pyramid has come crashing down during a school performance gone awry, injuring six students.

The ten-storey high formation was captured at a junior high school in Yao City in the Osaka prefecture of Japan, where the dangerous stunt is still viewed as a customary means of bonding.

A cringeworthy video has emerged showing the moment a 150-student strong human pyramid collapses down

The video shows the near-perfectly formed pyramid breaking up moments before the crowning student raises the Japanese flag.

The student hesitates several times as he prepares to stand up, with the horde of bodies below him visibly swaying under the pressure.

The boy had just found his footing at the peak of the pyramid when the throng of bodies comes crashing down, accompanied by a soundtrack of gasps from shocked classmates.

One student suffered a fractured arm and five others were injured in the dramatic collapse, reports 9 News.

Injuries from human pyramids are common in Japan, with 6,500 recorded injuries recorded in 2012, one of which was a student who suffered permanent spinal damage.

Despite the risk, the acrobatic feat remains on the curriculum in many schools and some of them proudly display photos of students performing the stunt.

The student at the top of the pyamid was moments away from raising the flag and finishing the job
