The shinbashira was put to the test before Tokyo Skytree was even finished. When the Great East Japan Earthquake struck on March 11, 2011, the tower was still under construction, but the shake-reduction technology worked as planned, and all construction staff members on site were safe that day. The structure was also unscathed, and just a week later, on March 18, workers affixed the lightning rod to the top of the tower, bringing it to its full height of 634 meters.

It is necessary to make sure that the earthquake-proof construction is perfect. Usually hundreds of workers sway the large building just after the earthquake-proof system is introduced. In this sense, the earthquake occurred on the very timely moment.

The Tohoku earthquake is not the only case. In Japan, earthquakes often occur very timely. In 1923, the Great Kanto earthquake occurs on the opening day of the Imperial Hotel. In 1995, the Great Hanshin earthquake occurs almost on the timing of the introduction of the earthquake-proof pendulum system.
